Hello,

I suppose equations are:

x+y=3 (1)
x+2y=9 (2)

(2)-(1)==>y=6
(1)==>x=3-6

x=-3, y=6
Sol={(-3,6)}

Oscar is buying 4 new tires for his car. He has $240 budgeted for the tires, but can afford to pay $35 more or less than that am
Pachacha [2.7K]

Given that the dealer sells a dozen tires for $240, every 3-tire set costs $60. There are six 2-tire sets in a dozen. Thus, his total revenue should be $360. The total profit is the difference between the total revenue and the total cost. The answer is therefore, the first choice, $120.

6. The total cost of materials to build the foam
Sophie [7]

Answer:

Cost of Material per square foot = $1.7

Step-by-step explanation:

Given:

Length = 24

Width = 12

Height = 6.5

Find:

Cost of Material per square foot

Computation:

TSA of pit = 2[bh + hl] + lb

TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)

TSA of pit = 2[78+156] + 288

TSA of pit = 756 square foot

Cost of Material per square foot = 1,285.20 / 756

Cost of Material per square foot = $1.7
