35? If they charge $5 a movie and if you rent 7 of them, 7x5=35 ..
Answer:
l = 14 inches , b = 6 inches
Step-by-step explanation:
multiply length l and breadth b by the scale factor , then
new length =
× 35 = 2 × 7 = 14 inches
new breadth =
× 15 = 2 × 3 = 6 imches
Change to y = mx + b format
X - y = 16
-y = -x + 16
So slope = - 1 / 1
You would have to insert the number into the variable. For example,
![3x - 27 = 18](https://tex.z-dn.net/?f=3x%20-%2027%20%3D%2018)
Then, you would isolate the x value (3x).
![3x = 18 + 27](https://tex.z-dn.net/?f=%203x%20%3D%2018%20%2B%2027)
Simplify.
![3x = 45](https://tex.z-dn.net/?f=%203x%20%3D%2045)
Finally, divide both sides by the coefficient.
![\frac{ 45}{3} = \frac{3x}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%2045%7D%7B3%7D%20%3D%20%5Cfrac%7B3x%7D%7B3%7D%20)
You end up with
Answer:
x=20
Step-by-step explanation:
This is a right triangle, so we can use the pythagorean theorem to help us find x.
The the theorem states that the sum of the legs squared is equal to the length of the hypotenuse squared.
Thus, our equation is:
x^2+48^2=52^2
Simplify.
x^2+2304=2704
Subtract 2304 from both sides.
x^2=400
Find the square root of both sides.
x=20
