Marco is selling floral arrangements. each arrangement uses 1 vase and 11 orchids. each vase costs marco $4.00.let c be the total cost of the arrangements and r be the cost of 1 orchid .which equation should marco use to find the total cost of each arrangements? answer the question correctly i'm giving 15 points

The total cost of each arrangement is c = $4.00 + (11*r)

Step-by-step explanation:

each arrangement has 1 vase and 11 orchids.

1 vase = $4.00

c = the total cost of the arrangements

r = the cost of 1 orchid

The formula to determine the total cost of each arrangements, as below

the total cost of each arrangement = 1 vase + ( 11 * the cost of 1 orchid)

                                                    c = $4.00 + (11*r)

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
