Answer:

3) r = 1.5

7) y = 18

11) x = -10

Step-by-step explanation:

3) Isolate the variable by dividing each side by factors that don't contain the variable.

7) Solve for y by simplifying both sides of the equation, then isolating the variable.

11) Move all terms that don't contain x to the right side and solve.

Which expression represents the phrase "twice the difference of a number and 5"?
KatRina [158]

The expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).

<h3>What is the expression that represents the phrase?</h3>

The difference of a number and 5 is given by:

x - 5.

As we don't know the number, hence we call it x.

Twice that is:

2(x - 5).

Hence the expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).

A similar problem, in which the expression that represents a phrase is found, is given at brainly.com/question/2164351
