Answer:
M= -7
Step-by-step explanation:
M+9=2
M =2-9
M=-7
Answer:
To express the sum of two numbers using distributive property, we factor out the highest common factor (HCF) of the two numbers (i.e. the greatest number that can divide the two numbers without remainder)
28 = 2 x 2 x 7
42 = 2 x 3 x 7
The HCF of 28 and 42 is given by 2 x 7 = 14
Therefore, we express 28 + 42 using distributive property thus: 14(2 + 3)
24, since 54-30 is 24, and 30+24 is 54.
The inequality can be:

Now you divide both sides by 150 to get the #of boxes.

Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20
5(4+y) is the correct answer, you would be adding 4 and y then multiplying the sum by 5
