After 4 hours, Randy had traveled 228 miles. If he travels at a constant speed, how far will he have traveled after 9 hours?

513 miles

Step-by-step explanation:

228/4 = 57

57 * 9 = 513

513

Step-by-step explanation:

he travels 57 miles every hour, we can find this out by doing 228/4

then doing 57*9 and we get 513

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
