The volume of a rectangular prism is computed by a formula volume = length times width times height. So base on your given the volume is represented by x^3+11x^2+20-32 and the width is x-1 and height is x+8 the length is x+4 i hope i answered your question
We can solve x through simple algebra.
x + 5 = 2
x = 2 - 5
x = -3
x - 10 = 22
x = 22 + 10
x = 12
x - 27 = 8 + 10
x - 27 = 18
x = 18 + 27
x = 45
-11 + x + (-48) = 25
-11 + (-48) + x = 25
-59 + x = 25
x = 25 + 59
x = 84
x - (-16) = 12 + 13
x + 16 = 25
x = 25 - 16
x = 9
Tip: As you can see, the number sign changes as they shift from left to right (ex. -59 to +59).
Answer:
Answer:
18 cups.
Step-by-step explanation:
We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: .
To find number of cups x to make a profit of at least $20 we will use our given inequality.
Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.
Answer:
2.99x + 12.99y = 43.92
Step-by-step explanation:
socks cost 2.99 and she bought x
2.99x
blouses cost 12.99 and she bought y
12.99y
The total is
2.99x + 12.99y
The total cost was 43.92
2.99x + 12.99y = 43.92
