James bought two T-shirts and one pair of jeans at an online store and paid $40, not including taxes, for his purchase. A month
SVETLANKA909090 [29]

Answer:

The T-shirts cost $10 and the jeans cost $20.

Step-by-step explanation:

I guess you want to find the cost of the T-shirts and jeans at his first buy,

Let the cost be  $t and $j for T-shirts and jeans respectively.

Then we have the system:

2t + j = 40...................(1)

and a month later:

0.5*2t  + 0.5*5j = 60

t + 2.5j = 60................(2)

Multiply by - 2:

-2t - 5j = -120.............(3)

Adding equations (1) and (3):

-4j = -80

j = -80 /  -4

j =  $20.

Substituting j = 20 into equation (2):

t + 2.5(20) = 60

t = 60 - 50

t = $10.

t = $55

George wants to put carpeting in a rectangular living room and a square bedroom.The length and width of the living room is 12 fe
erastova [34]

Answer:

Expression:  3.5((12x18) + 13²)

Step-by-step explanation:

Since George is going to put carpeting in two different rooms, one rectangular and one square, you need to find the area of each room, add the sum and then multiply the total area needed by the cost per square foot of carpet.  The area of a rectangle is: a = lw, where l=length and w = width.  The area of a square is: a = s², where s = side of the square.  Take the sum of these two areas would be (12 x 18) + 13² or 213 + 169 = 382.  Since the cost of the carpet is the same per square foot, you can multiply the entire sum by the cost of $3.50 or:  3.5((12 x 18) + 13²) or 3.5(382) = $1,337.
