Write an algebraic expression that models the word phrase.
the sum of the product of a number x and 12, and 8
choose the correct answer below.
a. 8x + 12
b. 12x + 8
c.(12+8)x
d. 96+x

B

Step-by-step explanation:

The product of a number x and 12 means

multiply x and 12

that is:

12*x

=12x

The sum of THIS and 8 would thus be:

12x + 8

So we can see answer choice B is right.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
