determine if each of the following expressions is equ
each of the following expressions is equivalent to 24 - 6x. explain your
reasoning for each.

a. Yes

b. Yes

c. Yes

d. No

Step-by-step explanation:

a. Because -10x+4x=6x

b. 2(12-3x)=2*12-2*3x=24-6x

c. 24 and -6x just switched places.

d. 24x-6x=18x not 24-6x

The answer is 53.

Step-by-step explanation:

If you know what x equals, just plug it in. Since we know x = 9, plug it in to the expression.

The new expression would be 5 x 9 + 8.

Then solve. Multiply the 5 and 9 first:

5 x 9 = 45

Finally, add the 8:

45 + 8 = 53.
