Question 3
Use distributive property to simplify:
3(x + 2)

Question 4 options:

3x + 6

3x + 2

6x

3/2

answers

question 1 = -0.5

question 2 = 6 - 3y

question 3 = 3x + 6

question 1

to evaluate (x + 1)/3 when x = -2.5, plug the value of x into the equation

(x + 1)/3

= (-2.5 + 1)/3

= (-1.5)/3

= -0.5

question 2

to solve this, distribute the 1/2 through the parentheses

(1/2) * (4 − 6y + 8)

= (1/2 * 4) + (1/2 * -6y) + (1/2 * 8)

= 2 + (-3y) + 4

= 6 - 3y

question 3

to solve this, distribute the 3 through the parentheses

3(x + 2)

= (3 * x) + (3 * 2)

= 3x + 6

note - i tried to plug -2.5 into x + (1/3) for question 1, but the answer wasn't among the solutions, so i assumed the equation was (x+1)/3 instead since its answer was among the solutions

Answer for the first question is not there. so,answer is 2.167

=6-3y

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
