1. Which value of x satisfies the equation below? - 2x - 7 = 12
A. x = -9.5
B. x = -9
C. x = 9
D. x = 9.5

A.x=-9.5

Step-by-step explanation:

-2x-7=12

move the constant to the right

2x-12+7

calculate

2x=19

divide both sides

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

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.
