Roberto has already run 16 of 26.2 miles of a marathon. rounded to the nearest whole number, what percent of the marathon has he completed? i know

62%.

Step-by-step explanation:

We are given that marathon is 26.2 miles long and Roberto completed 16 of this marathon.

Now let us find 16 is what percent of 26.2.

Now let us round our answer to nearest whole number. rounded to nearest whole number will be .

Therefore, Roberto ran 61% of the marathon.

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
