To answer the question, let x be the cost of a bedsheet and y that of a towel. The first purchase can be expressed as,
38x + 61y = $791.50
and the second as,
54x + 50y = $923
Solving for x and y simultaneously will give, x = $12 and y = $5.5. Thus, each bedsheet costs $12 and each towel cost $5.5.
Answer:
x = 21 / 228
Step-by-step explanation:
4x - 10y = - 3 -----> equation 1
112x + 5y = 12 -----> equation 2
Multiply 2 on both sides in the equation 2,
2 ( 112x + 5y = 12 )
224x + 10y = 24 -----> equation 3
Add equations 1 & 3,
4x - 10y = - 3
224x + 10y = 24
_____________
228x + 0 = 21
228x = 21
x = 21 / 228
Answer:
A = 7.5in^2
Step-by-step explanation:
Your a (base) is 4, which is A-P.
Your b (base) is 1, which is T-R.
Your h (height) is 3, which is the distance from the bottom of the trapezoid to the top.
Then you plug it into your formula, A = (a + b) x h/2 (A = (4 + 1) x 3/2)
That equals 7.5.
