Write and evaluate the expression. Then, select the correct answer. Ten times the sum of seven and a number; evaluate when j= 1

10(7 + j); when j = 1, the value is 80

Step-by-step explanation:

i did the assignment

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.
