Answer:
10
Step-by-step explanation:
10 is the greatest common factor of 20 and 30
X = -33 + 42
x = 42 - 33
x = 9
First we need to find the square footage of her ceiling, since it's a square just multiply the side by the side: 44•44=1936. Now divide the square feet by how many feet each can can paint: 1936/242=8. Jenny would need exactly 8 cans of paint to paint her ceiling :)
Answer:D?
Step-by-step explanation:
Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation
Solution:
4 (x-3)=16
4x - 12 = 16
4x = 16 + 12
4x = 28
x = 7
4x - 3 = 16
4x = 16 + 3
4x = 19
x = 19/4
x = 4.75
