1. the yeoman family spent a total of $26.75 on lunch. they bought 5 drinks and 3 sandwiches. each drink costs $2.50 less than a sandwich. which of the following equations could be used to find the cost of each sandwich?

a. 26.75 = 5(2.50) + 3s

b. 26.75 = 3(2.50) + 5s

c. 26.75 = 5s+ 3(s + 2.50)

d. 26.75 = 3s + 5(s - 2.50)

2. solve the equation for a rounded to the nearest tenth:
3a - 0.3 ( a + 50) = 75

a. 5.6

b. 22.2

c. 27.3

d. 33.3

$12. that is my answer.

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
