The mean quiz score for 8 students is 50 . The scores for 7 of the 8 students are shown below. What is the score for the remaining student?

70

Step-by-step explanation:

Add all the scores we have so 20×3=60,+30,80×3=240

60+30+240=330

Then we see the mean that is for the 8 students score which is 50.

If you times 8 by 50 you will see all the scores added together so 50×8=400

400-330=70

70 is the score of the remaining student.

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
