Answer:
16 cups of cashews
12 cups of almonds
Step-by-step explanation:
Let's say x is the cups of cashews and y is the cups of almonds.
We can write two equations:
x / y = (1/3) / (1/4) = 4/3
x + y = 28
Solve the system of equations using substitution.
x = 4/3 y
4/3 y + y = 28
7/3 y = 28
y = 12
x = 16
Answer:
Your answer should be $29.40
Step-by-step explanation:
If you divide 21 by 5 you get 4.2, so each book costs $4.20.
4.2 x 7 = 29.4
Therefore, your total cost for 7 books will be $29.40

Answer:
The answer
Step-by-step explanation:
the width of a rectangular prism which has a height of 10 feet and a length of 14 feet should be 140 square feet
To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)
So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20
Hope this helps
