Answer:
3 a²b
Step-by-step explanation:
This is what I did:
3 a²b ( 5b² - 7a²)
when you try to expand this, it will give you back the original expansion so 3a²b is the greatest common factor
Answer:
1/9
Step-by-step explanation:
when you have a negative exponent, you move the term to the denominator: 1/3^2

Answer:
200 minutes
Step-by-step explanation:
Given that:
Cellular - Tastic (f) :
Monthly fee = $35
Per minute fee = $0.11
Dirt cheap call (g) :
Monthly fee = $55
Per minute fee = $0.01
How many minutes would you need to use for the cell phones to cost the same
amount?
Let number of minutes for cost to be equal = x
35 + 0.11x = 55 + 0.01x
Collect like terms
0.11x - 0.01x = 55 - 35
0.1x = 20
x = 20/0.1
x = 200
Hence, for cost to be the Same, 200 minutes must be used
Hello from MrBillDoesMath!
Answer:
x = V/(y*z)
Discussion:
V = x * y* z => (divide both sides by y*z)
V/(y*z) = (x*y*z) / (y*z) =>
V/(y*z) = (y*z) * x / (y*z) => ( as (y*z)/(y*z) = 1)
V/(y*z) = 1 * x =>
V/(y*z) = x
Thank you,
MrB
