Answer:
5 hours
Step-by-step explanation:
39 - 14 = 25
5 x 5 = 25
14 + 25 = 39
Answer:
5 hours
Step-by-step explanation:
John needs $39.00, he has $14 now, and He earns $5 a week working. x= how many hours.
Start by setting the equation,
$39.00= $5x + $14.00
Then solve by
1) subtracting 14 from both sides;
39(-14)= 5x+14(-14), by subtracting 14 on both sides you cancelled out the 14;
39 -14 = 5x becomes $25= 5x (39 -14 =25)
2) divide both sides by 5 to get x alone
25 (/5)=5x (/5) which becomes 25/5=x
3) 25/5 is 5

the area of rectangle is x^2-3x+2. Find a possible length and width of the rectangle.
Answer:
x - 2 and x - 1 can be possible length and width of the rectangle.
Step-by-step explanation:
Area = x² - 3x + 2
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
To find possible length and width we can factorize the above expression.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
x² - 3x + 2 ( 2 = -1 × -2 )
x² - x - 2x + 2 ( 3 = -1 + -2 )
x(x - 1) + -2(x - 1)
(x - 2) (x - 1)
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
x - 2 and x - 1 can be possible length and width of the rectangle.

A new cookbook is becoming popular. The local bookstore ordered 4 copies in October, 6
copies in November, 9 copies in December, and 13 copies in January. If this pattern
continues, how many copies will the bookstore order in February?
Answer:
18 book copies
Step-by-step explanation:
As you can see, there is a pattern where you add the next number after x. To find where to start, let's subtract the numbers we were given:
6 - 4 = 2
9 - 6 = 3
13 -9 = 4
So our next number is to add 5 to 13: 5 + 13 = 18, so in February the bookstore will order 18 books.

It rained all day on Mother's Day and the temperature dropped fourteen and seven tenth degrees. The next day the rain stopped and the temperature rose ten and nine tenths degrees. If the temperature at the beginning of Mother's Day was sixty five and eight tenths degrees, what was the temperature at the end of the day after Mother's Day?
Answer: The temperature was 1 8/10º at the end of the day after Mother's Day
Step-by-step explanation:
5 8/10º-14 7/10º=-9 1/10º at the end of Mother’s Day
-9 1/10º+10 9/10º=1 8/10º at the end of the next day after Mother’s Day
The function rule of a certain function is y = -3x + 1. If the input is 7, what is the output?
Answer:
-20
Step-by-step explanation:
y = -3x+1
if the input is 7, it means x=7 so substitute in the equation
y= -3*7+1 = -21+1= -20 which is the output

65.6g of sugar is needed to make 8 cakes how much is needed to make 5
Answer:
41g
Step-by-step explanation:
65.6/8= 8.2g per cake
8.2*5 cakes= 41g
Answer:
41g of sugar.Step-by-step explanation:
65.6g = 8 cakes
We need to find the sugar for 1 cake:
65.6 ÷ 8= 8.2 (gram for 1 cake)
The sugar for 5 cakes:
8.2 × 5= 41 (gram for 5 cakes)

4x-7y=3
x-7y=-15
Answer:
x = 6, y =3
Step-by-step explanation:
4x-7y=3
x-7y=-15
Multiply the first equation by -1
-4x+7y=-3
Then add this to the second equation to eliminate y
-4x+7y=-3
x-7y=-15
------------------
-3x +0y = -18
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
Now find y
x -7y = -15
6 -7y = -15
Subtract 6 from each side
6-7y-6 = -15-6
-7y = -21
Divide by -7
-7y/-7 = -21/-7
y =3

9514 1404 393
Answer:
-1
Step-by-step explanation:
Solving the given equation for y, we have ...
x -y = 18
y = x - 18 . . . . . add y-18
The coefficient of x is 1. That is the slope of the given line. The desired perpendicular line will have a slope that is the negative reciprocal of this:
m = -1/1 = -1
The slope of the perpendicular line is -1.

The graph shows you that a line with slope -1 is perpendicular to the given line.
if triangle ABC=triangle DEC, and angle b=3x and angle e=6x-39, what is x
The value of x in the expression is 13.
What is a Triangle?A polygon which has three sides and three vertices is called as triangle.
The sum of all the angles of the triangle is 180°.
Given:
The triangle ABC = triangle DEC,
and angle b=3x and angle e=6x-39.
To find the value of x:
We know,
b = e
So, substituting the values,
3x = 6x - 39
3x = 39
x = 13.
Therefore, the value of x is 13.

A ski club rents cross-country skis. The table below shows the cost of rentals for two and four days. Number 1 2 3 of Days Rented Rental Cost ($) 12 17 22 27 Which explicit formula models the cost of renting skis from the club? o an . = 12 + 5n O an . 10n An = 5 + 5n O an an = 7+5n
Answer:
an = 7 + 5n
Step-by-step explanation:
First we know that for each number of days rented the cost increase by 5 so we get an - (?) + 5n.
We also know the first number is 12 for 1 day, so for 0 days, or the starter cost, is 7. We get this by subtracting 5 from 12.
Hence the answer an = 7 + 5n

Answer:
10.92 cm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b= 2.8 and h = 7.8 , then
A = [tex]\frac{1}{2}[/tex] × 2.8 × 7.8 = 1.4 × 7.8 = 10.92 cm²
