For questions 4a–4d, choose Yes or No to tell if the number 7.15 will make each equation true. 4a) 4.95 +7.15= 12.1 ○ Yes○ No
4b) 10.82 - □=3.77 ○ Yes○ No
4c) 8.47 + □ =15.52 ○ Yes○ No
4d) 9.14 - □= 1.99 ○ Yes○ No

1/3 + 1/5 = 8/15.

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
