Maggie used the commutative property to write StartFraction 4 Over 5 EndFraction 6. 9 y minus 8 as the equivalent expression 6.
1 answer:
No, some of the terms changed signs, the correct option is C.
Given
Maggie used the commutative property to write;
The commutative property of addition states that the sum of any two numbers remains the same even when the position of the numbers is interchanged.
Then,
She did not apply the commutative property correctly because she changed the signs of 4/5 and 8 and in consequence, the result will not be the same.
A, B and C, for a commutative property
(A+B)+C = C+(A+B)
4/5 + 6.9y - 8 as the equivalent expression of:
6.9y + 8 - 4/5
Hence, No, some of the terms changed signs.

Answer:
The new amount paid to mechanics per after by new owner is $ 19 Answer
Step-by-step explanation:
Given as :
The amount paid to mechanics initially = $ 20 per hour
Now, The new owner paid less at the rate = 5%
Let the amount paid to the mechanics after 5 % less = x per hour
So, According to question
The new amount paid to mechanics per hour = initial amount paid per hour × ( 1 - )
or, The new amount paid to mechanics per hour = $ 20 × ( 1 - )
I.e The new amount paid to mechanics per hour = $ 20 × 0.95
∴ The new amount paid to mechanics per hour = $ 19
Hence The new amount paid to mechanics per after by new owner is $ 19 Answer
