P=2*(l+w)
p=2l+2w
2w=p - 2l
w= (p-2l)/2
Answer: d=12
Step-by-step explanation:
Multiply both parts of the equation by 8:
Divide both parts of the equation by 11:
Answer: H
Step-by-step explanation:
In this question, the first information that we get is that Kayla spent half of her weekly allowance in clothes. On cleaning the oven Kayla gets $4. Finally Kayla is left with $12.
Let us assume that the weekly allowance of Kayla = x
Amount of allowance saved after buying clothes = x/2
Then we can go for the equation
x/2 + 4 = 12
x + (4 * 2) = 12 * 2
x + 8 = 24
x = 24 -8
= 16
So we can now see that the weekly allowance of Kayla is $16
7/8*8/9 = (7*8)/(8*9)
Since we have an 8 both above and below, we can erase it, and so the answer is 7/9
