A. The expression for the problem is 10+ 2x (10 dollars a week plus 2 per chore.)
B.10 +2(5) =$20
C. 10(4)+2x=144 // 40+2x=144 //2x=104 // x=52 (she will need to do 52 chores :)
The answer is 122. If this is correct, please mark me brainliest.
Question 3 is 10. question 4 is also 10.
Answer:
x = 30
Step-by-step explanation:
We have to find x
Given that:
20% of x = 12 % of (x +20)
This can be written as:
0.2(x) = 0.12 (x + 20)
0.2x = 0.12x + 2.4
Subtracting 0.12x from both sides we get:
0.2x - 0.12x = 0.12x - 0.12x + 2.4
0.08x = 2.4
Dividing both sides by x we get:
0.08/0.08x = 2.4/0.08
x = 30
I hope it will help you!
