You are correct the answer is a:18
Answer:
Step by Step
first, I'll divide the big shape into 3 smaller ones. it will be the rectangle on the top (10x8), the square below that (10x10), and the triangle on the right (7x10/2)
if I calculate all, I get 80cm squared, 100cm squared, and 35cm squared.
if I add them all up, I get
80+100+35=215cm squared

Answer: cost of T-shirts = $18
cost of sweatshirt = $42
Step-by-step explanation:
Let the cost of T-shirts be x
Let the cost of sweatshirt be y
The information given in the question can be used to form an equation that'll be:
9x + 3y = 288 ...... i
1x + 6y = 270 ........ ii
Multiply equation i by 1
Multiply equation ii by 9
9x + 3y = 288 ....... iii
9x + 54y = 2430 ..... iv
Subtract iii from iv
51y = 2142
y = 2142 / 51
y = 42
The cost of a sweatshirt is $42
Since Carson sells 1 T-Shirt and 6 sweatshirts for 270$. The cost of a t-shirt will be:
= 270 - 6(42)
= 270 - 252
= $18
The answer would be $13.875
Answer:
19 cm
Step-by-step explanation:
Let x be the length
The width would be x+11 since it's 11 cm longer
Perimeter = 2(length+width)
54 = 2(x+x+11)
54 = 2(2x+11)
54 = 4x+22
4x = 32
x = 8
Width = x+11
Width = 8+11
Width = 19
