Answer:
2
Step-by-step explanation:
To find the answer we just need to reverse the operation. So to find the cubic root of 8.
![\sqrt[3]{8\\}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%5C%5C%7D)
That equals 2 since 2*2*2=8
20^2 = 16^2 +x^2
400= 256+ x^2
x^2 = 400 -256
x = 144^1/2
=12
b. yes
X - 9/3 = 2
Simplify 9/3, 9/3 = 3
x - 3 = 2
Add 3 on both sides
x = 5
I would say the original price was $512 because its now 1/4
so... 128 * 4= 512
Answer:
177 pounds
Step-by-step explanation:
Create an equation to represent the system.
Since it's 18% more than what was used last month an equation can be written such as the one below:
(118%)( last month's cheese ) = this month's cheese
Convert the percentages into decimals by moving the decimal place at the end of 118.00 two places to the left
118% = 1.18
( 1.18 )( last month's cheese ) = this month's cheese
Next, plug in the number for last month's cheese
( 1.18 )( 150 pounds) =
177 pounds
