Amy can wash 75 cars in 12 hours, Roger can wash 64 cars in 12 hours.
so therefore 75+64 =139
together they can wash 139 cars in 12 hours
32/8= 4
so Donald uses the pack of 48 screws a total of 4 times to build 32 desk
48 x 4 = 192
so he used 192 screws total
Answer:
Combine the terms with the same variable
Step-by-step explanation: so 9x-4x+9x-4x
3 x 4 = 12
12/12 - 1/3 ( so 4/12) = 8/12
8/12 - 1/4 ( so 2/12 as you only have 8/12 left) = 6/12
Answer = 6/12 = 1/2 or 50%
Answer:
The answer would be -4.36.
