Answer:
<h2>
030 cal</h2>
Step-by-step explanation:
I think you can do this way:
Volume = B*h where B is the area of the base.
B= 4 * 10 = 40
V= 40 * 15
V= 600 cm^3
First, you have to set up two equations.
X + y = 45
18x + 24y = 1,050
To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18.
-18x -18y = -810
This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought.
Then, you have to substitute 40 for y in the first equation and solve for x.
Answer:
B) 6/7x2 = 1 5/7
Step-by-step explanation:
6/7 (2)
= ( 6/7) (2/1)
= (6)(2)/(7)(1)
12/7 or 1 5/7
