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:D
Step-by-step explanation:
You know that the card picked is an 8, so forget the rest of the deck (they are trying to trick you into thinking it is 2 cards out of 52 cards). So there are 4 8's in a deck. 2 are red, 2 are black. You have a 2/4 chance of pulling a red. 2/4 = 1/2

second multiply 5.50 by 9
she would only earn 49.50 so she won’t be able to buy the bike and helmet
Answer:
4
Step-by-step explanation:
Plug in each given value into the expression to see if it is true.
Set given: {2 , 3 , 4}
Equation given: x + 2 = 6
First, plug in 2 for x. When x = 2:
x + 2 = 6
(2) + 2 = 6
4 ≠ 6.
Next, plug in 3 for x. When x = 3:
x + 2 = 6
(3) + 2 =6
5 ≠ 6.
Finally, plug in 4 for x. When x = 4:
x + 2 = 6
(4) + 2 = 6
6 = 6 (True).
In the given set, only 4 complete the equation.

Answer:
1 m³
Step-by-step explanation:
first find volume of smaller cubes
V = lwh
S = 1/3*1/3*1/3
S = 1/27
find volume of large cube. there are 27 smaller cubes.
V = 27S
V = 27(1/27)
V = 1
S: volume of small cube
V: volume of large cube
