Answer:
check your math
Step-by-step explanation:
The first subtraction was correct:
36 -7 3/4 = 28 1/4
The second subtraction needs to be revisited.
28 1/4 -6 2/4 = 27 5/4 -6 2/4 = 21 3/4
__
You can do what you did, but you need to pay attention to the signs.
28 1/4 -6 2/4 = (28 -6) +(1/4 -2/4) = 22 - 1/4 = 21 3/4
The result of subtracting 2/4 from 1/4 is -1/4, not +1/4.
_____
The length of the first cut piece was 21 3/4 inches.
Answer:
-2 1/6
Step-by-step explanation:
4(-2 1/3) + 7 1/6
-9 1/3 + 7 1/6
-2 1/6
#1: 4(x + 3)
We just have to distribute the 4 throughout the rest of the problem. So, (4 times x) + (4 times 3) = 4x + 12
#2: -7(4 - y)
This is the same concept, but with a negative sign at the front. So, (-7 times 4) - (-7 times y) = -28 + 7y
It might be k, since 4-4 is 0 and 0 has no absolute value.
