Answer:
D. -6m²n² + 10m²n + 8mn² - 10mn
Step-by-step explanation:
(-7mn + 8mn² - 8m²n²) + (10m²n + 2m²n² - 3mn)
Apply the distributive property to remove the parentheses
-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn
Combine like terms together and arrange in standard form
-7mn + 8mn² - 8m²n² + 10m²n + 2m²n² - 3mn
-8m²n² + 2m²n² + 10m²n + 8mn² - 7mn - 3mn
-6m²n² + 10m²n + 8mn² - 10mn
8. Simon is saving his money to buy an Xbox. He earn money by mowing lowns for his
neighbors. The situation can be represented using the equation 35x - 2y = -42 where x
represents the number of lawns mowed and y represents the amount of money Simon has in his
bank account.
( explainations are muc appreciated:) )
a. How much money does Simon earn for mowing each lawn?
b. How much money was in Simon's bank account before mowing any lawns?
Answer:
a. $35
b.$21
Step-by-step explanation:
a. It is what your are multiplying the number of lawns mowed by
b. -2y = -42
divide by -2 on each side
y=21
(you don't need the 35x because we are trying to find how much before he started mowing)

A
Step-by-step explanation:
A because a markup means the price times the number given which was 32% and 32% is the same as 0.32.
p=7q-3 make q the subject
Answer:
q = (P + 3) / 7
Step-by-step explanation:
Give the expression :
P=7q-3
To make q the subject
Isolate 7q by adding 3 to both sides
P + 3 = 7q + 3
P + 3 = 7q
To. Isolate q alone, multiply both sides by 1/7
(P + 3) * 1/7 = 7q * 1/7
(P + 3) / 7 = q
q = (P + 3) / 7
Rebecca carries a balance on her credit card each month. Today is the first day of the new, 28-day billing cycle. The current balance is x and the APR is 24%. Rebecca is buying a friend an expensive gift that costs $1,400 that she plans to put on her credit card. This will be her only purchase this month, and she will be making this purchase on the last day of the month. If her finance charge will be $51, write and solve an equation to determine her current balance on her credit card.
Answer:
Average date*Interest=Finance charge
Previous debt*2%´+1400*2%=51
Previous debt=1150
Step-by-step explanation:

Is -351 in the sequence below 27,25,23,21,19
Answer:
Yes
Step-by-step explanation:
To find the next number in the sequence, you have to subtract 2 from the last number.Because it started on 27 (which is an odd number) and we're subtracting 2 each time, every number in the sequence will be odd. And because -351 is an odd number, it will be in the sequence.I hope this helps!

find the slope of the line
Answer:
y= 3 + 3/4x sooooooo 3/4 is the slope... I think
Answer:
3/4
Step-by-step explanation:
You can use the x- and y--intercepts since they are easy-to-read points.
x-intercept: (-4, 0)
y-intercept: (0, 3)
To go from (-4, 0) to (0, 3), go up 3 and right 4. That is a rise of 3 and a run of 4.
slope = rise/run = 3/4
Answer: slope = 3/4
Write an equation to represent the number of pages Jesse has read. Using x, the number of days Amir has been reading, write an expression to represent the number of days Jesse has been reading. Remember that Jesse started reading one day before Amir. Use this expression to write an equation for the number of pages Jesse has read. Let y represent the number of pages read.
Question:
Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.
How many days will it take Amir to catch up to Jesse, and how many pages will they each have read?
Write an equation to represent the number of pages Amir has read. Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.
Answer:
It will take 6 days
Step-by-step explanation:
For Jesse:
[tex]Rate = 30\ pages/day[/tex]
This implies that Jesse will cover 30y in y days
For Amir:
[tex]Rate = 35\ pages/day[/tex]
This implies that Amir will cover 35x in x days
Because Amir starts a day later,
[tex]y = x + 1[/tex]
So, we have the following equations:
[tex]Jesse = 30y[/tex]
[tex]Amir= 35x[/tex]
[tex]y = x + 1[/tex]
To get the number of days when they read the same number of pages, we have:
[tex]Jesse = Amir[/tex]
Substitute values for Jesse and Amir
[tex]30y = 35x[/tex]
Substitute x + 1 for y
[tex]30(x+1) = 35x[/tex]
Open bracket
[tex]30x+30 = 35x[/tex]
Collect Like Terms
[tex]30 = 35x-30x[/tex]
[tex]30 = 5x[/tex]
Solve for x
[tex]\frac{30}{5} = \frac{5x}{5}[/tex]
[tex]\frac{30}{5} = x[/tex]
[tex]6 = x[/tex]
[tex]x = 6[/tex]

A TV has an original price of $599. Enter the new price after the given percent of change.
20% increase
The percent decrease is ? %
Answer:
The new price = $718. 8
Step-by-step explanation:
Original Price = $599
Given that the increase is 20%.
i.e.
Thus,
The amount of 20% Percentage increase = 20/100 × 599
= 0.2 × 599
= $119.8
Therefore,
New price = Original price + 20% increase amount
= 599 + 119.8
= $718. 8
Therefore, the new price = $718. 8
find x !!?????!!!????????????
Answer:
x = 15
Step-by-step explanation:
Given
See attachment
Required
Find x
The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.
So, we have:
90 + 6x + 5+ 10x - 40 + 4x + 5 = 360
Collect like terms
6x + 10x + 4x = 360 - 90 - 5 + 40 - 5
20x = 300
Divide both sides by 20
x = 15
Hence, the value of x is 15
What is the perimeter of ABC with vertices A (-2,9) , B (7,-3) , C (-2,-3) in the coordinate plane?
A. 21 units
B. 15 units
C. 34 units
D. 36 units
9514 1404 393
Answer:
D. 36 units
Step-by-step explanation:
Using the distance formula, we find the length of AB to be ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15
The line BC is horizontal, so its length is the difference of the x-coordinates:
BC = 7 -(-2) = 9
The line AC is vertical, so its length is the difference of the y-coordinates:
AC = 9 -(-3) = 12
The sum of the lengths of the sides of the triangle is ...
P = 15 + 9 + 12 = 36
The perimeter is 36 units.

What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ABC
Let the second triangle be represented as CDE
The measure of side AB = 2.5
The measure of side AC = x
The measure of side CE = 7
The measure of side ED = 3.5
Now , the two triangles are similar
So , corresponding sides of similar triangles are in the same ratio
Substituting the values in the equation , we get
AC / AB = CE / ED
On simplifying the equation , we get
x / 2.5 = 7 / 3.5
Multiply by 2.5 on both sides of the equation , we get
x = ( 2.5 x 7 ) / 3.5
x = 2.5 x 2
x = 5
Therefore , the value of x is 5
Hence , the measure of side x = 5

The ratio of boys to girls at a movie is 4:5. If there are 15 girls, how many boys are at the movie?
Answer:
There are 12 boys at the movie.
Step-by-step explanation:
Key skills needed in order to solve: Proportions, Ratios, and Multiplication
1) The ratio is 4 boys : 5 girls --> It can be written as a fraction --> 4/5
2) If there are 15 girls, we need to find the number of boys. let's say x is the number of boys when there are 15 girls. The ratio would then be x/15
3) Make a proportion --> [tex]\frac{4}{5}[/tex] = [tex]\frac{x}{15}[/tex]
You have to cross multiply here. You do the first fraction's numerator times the second fraction's denominator, and the first fraction's denominator times the second fraction's numerator.
4) This means you have to do: 4(15) = 5(x)
5) Multiply it out --> 60=5x
6) Divide by 5 and you will get x=12
Therefore there are 12 boys at the movie.

Answer:
-4 is an integer however NOT a whole number.
Step-by-step explanation:
Integer include numbers that can be written as a fraction(whole number) and their negative selfs. So: 1,2,3,4... and -1,-2,-3,-4...
Whole numbers are numbers that can be written as a fraction but do not include negative, so any number like: 1,2,3,4... but it can't be negative.

Haley worked 287 hours during the summer and earned $16 for each hour she worked.
Which is the closest estimate for the total amount she earned?
$4,500
$5,000
$5,500
$6,000
Answer: The closest estimate for the total amount she earned = $4,500
Step-by-step explanation:
Given: Total hours worked = 287 hours
Earning for each hour = $16
Total earning = (Total hours worked ) x (Earning for each hour)
= $ (287 x 16)
= $ 4592 ≈ $4500
The closest estimate for the total amount she earned = $4500
