Since both equal to 0
Do 8
thats because if you simplify you get 8
Answer:
8
Step-by-step explanation:
Let's start off by making both equal to each other, since they are both equal to 0
x²+5x+3=x²+bx+c
let's subtract x² from both sides
5x+3=bx+c
therefore
b=5 and c=3
5+3=8
How did you figure out the number of windows on 10 floors?
Answer:
There are 40 windows on the 10th floor
Step-by-step explanation:
Since we know one cube has 4 "windows" (each hole on its side not counting top and bottom) we can calculate that for each "floor" 4 more windows are added. So in other words, if "x" equals the amount of "floors" the equation for solving this would be 4x = # of windows.

The math club needs to raise more than $552.50 for a trip to the state competition. The club
has raised 12% of the funds. Which inequality shows how much money each of the 7 club
members needs to raise if each raises the same amount?
A
m< $69.45
В
m> $69.45
C
m<$72.35
D
m> $72.35
Answer:
A or B
Step-by-step explanation:
Leaning more towards B- u want the club to earn more not less
The correct inequality is m> $69.45
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
The math club needs to raise more than $552.50 for a trip to the state competition.
The club has raised 12% of the funds.
To represent the inequality we have to perform the following function
=552.50 x 0.12
=66.3
The amount remained= 552.50 - 66.3 = $486.2
So, for the 7 members = 486.2/7
= $69.45
Hence, the inequality is m>$69.45

1. Stephen works for an environmental protection agency
responsible for toxic waste cleanup. Stephen has to
remove the top 24" of contaminated soil in order to make
sure the soil is not a health hazard. The soil covers a
1200' x 1500'lot. How much soil must be removed?
Answer:
Area to be removed = 3600000 feet³
Step-by-step explanation:
We need to calculate the volume of soil to be removed. We have been already provided with area of the lot in feet.
Total Area of soil = 1200' x 1500'
Where soil to be removed is given in inches, convert it into feet
Soil to be removed = 24''=2'
Multiply both the the value to get the volume of soil to be removed so the soil is not a health hazard
Area to be removed = 1200' x 1500' x 2'
Area to be removed = 3600000 feet³
Find m∠YOZ in the figure if m∠XOZ = 86°.
Question 1 options:
A)
65°
B)
7°
C)
42°
D)
43°
One part of the angle is 3x, and the other part is 6x+23, so putting them together gets 9x+23=86. Subtract the 23 and we get 9x=63. We know that 9•7=63, so x=7, and now we can solve the angle. 6x=42, and 42+23=65, so the answer is:
A) 65°Answer:
A. 65
Step-by-step explanation:
First, you would need to find x.
You would combine both equations it would become, 6x+23+3x=86.
Then, combine like terms, 9x+23=86.
And subtract 23 from both sides, 9x = 63.
Lastly, divide both sides by 9.
x = 7
Now with the equation 6x+23, you replace x with 7, 6(7)+23.
Then multiply 42+23, and add 42+23= 65.

Which situation below would represent a negative rate of change:
John's parents put $40 on his school account for lunch. Each day he pays $3 for
lunch. Let y represent the amount of money John has after x days in his school
account.
Judy is babysitting after school and charges $20 a day. Each day she gets paid, she
puts half of what she earns in a savings account. Let y represent the amount of
money Judy has in her bank account after x days.
Answer: John's situation
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each situation.
John’s situation:
The amount of money that John has (y) is equal to his school account (40) minus the product of the number of days (x) and the amount he spends per day( 3)
y =40-3x
As days pass by, John has less money (negative rate of change)
Judy's situation
The amount of money that Judy has in her savings account (y) is equal to the product of the number of days (x) and the amount he saves per day (20/2)
y = x (20/2)

3 Euros can be exchanged for 22.41 Kroners. How many Euros can be exchanged for 100 Kroners?
Answer:
13.39 Euros
Step-by-step explanation:
The ratio between Euros and Kroners is 3:22.41. This means for every 3 Euros we get 22.41 Kroners. This also means for every Euro we get 22.41/3 = 7.47 Kroners. To calculate the number of Euros that can be exchanged for 100 Kroners, we simply divide 100 Kroners by our conversion factor. 100/7.47 = 13.3868809

Two lines are intersecting. What is the value of x?
(x + 40)°
(4x - 5)”
====================================================
Work Shown:
The two angles shown are a linear pair. They are adjacent and supplementary. Supplementary angles add to 180 degrees.
(4x-5)+(x+40) = 180
5x+35 = 180
5x = 180-35
5x = 145
x = 145/5
x = 29
--------
As a check, if x = 29, then
4x-5 = 4*29-5 = 116-5 = 111
x+40 = 29+40 = 69
The two angles are 69 and 111 degrees which add to 69+111 = 180, which helps confirm the answer.
Answer:
x = 29
Step-by-step explanation:
The two angles with measures are a linear pair.
Angles in a linear pair are supplementary, so their measures add to 180 deg.
4x - 5 + x + 40 = 180
Combine like terms on left side.
5x + 35 = 180
Subtract 35 from both sides.
5x = 145
Divide both sides by 5.
x = 29

help! plz and thx! what is 4:08 - 1:15 = ?:? plz, help WITH AND WITHOUT REGROUPING thx!!!!!!! I will give u the brainiest! plz and thx!
REMEMBER... I WILL GIVE U THE BRAINLIEST!!!!!!!
Answer:
2:53
Step-by-step explanation:
I believe that you are subtracting times here, so have in mind that if the first number indicates hours, and the second number minutes, and you are asked to subtract more of one quantity (minutes for example) than what you have, you will need to convert some of the hours into minutes.
Recall that 1 hour equals 60 minutes.
in the difference 4:08 minus 1:15, you sre expected to subtract minutes from minutes and hours from hours. Now the number of minutes you need to subtract from 08 is 15 (larger than 08) so we need to convert 1 hour into minutes in the first expression, and then (with enough minutes to deal with), we can subtract:
4:08 is the same as 3:68 where we converted 1 hour to 60 minutes and added those 60 minutes to the existing 8 .
Now the difference can be performed:
3:68 - 1:15 = (3-1):(68-15) = 2:53
Five times the smallest of three consecutive odd integers is seven more than twice
the largest. Find all three consecutive odd integers.
Answer:
5, 7, 9
Step-by-step explanation:
Using the information given we get:
[tex]5x-7=2z[/tex]
[tex]x+2=y\\y+2=z\\x+4=z[/tex]
[tex]5x-7=2(x+4)\\5x-7=2x+8\\[/tex]
Add 7 to both sides
[tex]5x=2x+15[/tex]
Subtract 2x from both sides
[tex]3x=15[/tex]
Divide both sides by 3
[tex]x=5[/tex]
Using these equations:
[tex]x+2=y\\y+2=z\\x+4=z[/tex]
and
[tex]x=5[/tex]
We get:
[tex]x=5\\y=7\\z=9[/tex]

6. Mr Chua's car consumes petrol at an average rate
of 8 litres daily. Before Mr Chua begins his journey,
he tops up the petrol in his car to 100 litres. Given
that he will next top up the petrol in his car when
there are 20 litres left, form an inequality and solve
it to find the maximum number of days he can travel
before he has to top up the petrol in his car. 10
Answer: He can travel up to 9 days before he has to top up the petrol in his car.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
The petrol available (100) minus the amount that his car consumes per day (8x) must be higher to 20 (liters left)
Mathematically speaking:
100- 8x > 20
Where x is the number of days.
Solving for x:
100-20>8x
80 > 8x
80/8> x
10>x
x <10
x must be less than 10 days .
He can travel up to 9 days before he has to top up the petrol in his car.

Answer:
x=19
Step-by-step explanation:
The 2 angles are inside of a right angle. We know this because of the little square in the corner. Therefore, they are complementary angles. When they are added together, they must equal 90 degrees.
3x+11+22=90
Combine like terms by adding 11 and 22
3x+33=90
We want to find out what n is. In order to do this, we have to get n by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
33 is being added to 3x. The opposite of addition is subtraction. Subtract 33 from both sides.
3x+33-33=90-33
3x=90-33
3x=57
x is being multiplied by 3. The opposite of multiplication is division. Divide both sides by 3.
3x/3=57/3
x=57/3
