Yhe cost for 7 dance lessons is 82. the cost for 11 dance lessons is 122. write and solve an equation to find the cost of 4 dance lessons

$52

Step-by-step explanation:

(7, 82)

(11, 122)

m= 122-82     40

      = = 10

       11-7           4

y - 82= 10(x-7)

y - 82= 10x - 70

y= 10x + 12

y= 10(4) + 12

y= $52

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
