Answer:17.7%
Step-by-step explanation:
132 x
____=_____
153 100
132(100)=153(x)
13200=153x
__________
153 153
x=82.3
100-82.3=17.7
Answer:
if she baked thirty cookies she has 30 cookies
Step-by-step explanation:
Answer:
6x = 42
Step-by-step explanation:
The formula to find the area of a rectangle is
. Since we have a value for the width, we simply need to find what to multiply to 6 to get 42.
Let x = length
6x = 42
We then divide both sides by 6 to find the value of x.
![\dfrac{6x}{6}=\dfrac{42}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B6x%7D%7B6%7D%3D%5Cdfrac%7B42%7D%7B6%7D)
![x=7](https://tex.z-dn.net/?f=x%3D7)
So we know the length is 7.
To check the answer we substitute x with 7.
![6(7)=42](https://tex.z-dn.net/?f=6%287%29%3D42)
![42=42](https://tex.z-dn.net/?f=42%3D42)
Both sides should be the same length..
Since we know that BC = 23 you need to find the value of x and put it in the formula.
23 = 2x+7
16 = 2x
x = 8
4x + 1 + 4(8) + 1 = 33 units
