28: 42=x: 54 what is the value of x.

We need to think, 28 / 42 = x / 54.

We need to do a proportion for this problem!

First, line up both fractions, then put a equal sign between both fractions.

28 / 42 = x / 54.

We multiply in a diagonal and then we divide by the one without a diagonal.

28 and 54 are a diagonal.

We multiply both numbers!

54 x 28 = 1,512.

Then, we divide by 42.

1,512 / 42 = 36.

Therefore, x = 36.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
