Ineed with d, pls list out the steps

to find d, you want to get all the numbers with the same denominator. since 210 is the largest number, and it can't be reduced, we want to set all the other denominators to 210.

our first number, 1/2, needs to be multiplied by 105 to get the denominator to be 210. the fraction will then be multiplied by 105/105 to get 105/210.

next, we want to get 1/6 to have a denominator of 210. 210/6 is 35, so we want to multiply 1/6 by 35/35 to get 35/210.

after that, we want to get 1/12 to have a denominator of 210. 12 goes into 210 17.5 times. we multiply 1/12 by 17.5/17.5 to get 17.5/210.

lastly, we 1/20 to have a denominator of 210 by mutiplying it by 10.5. 10.5/10.5 times 1/20 equals 10.5/210.

lastly we need to add all our converted numbers.

105/210 + 35/210 + 17.5/210 + 10.5/210 + 1/210 = 169/210

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
