Which statement about this equation is true?

Mathematics
1 answer:
Viktor [21]3 years ago
4 0
The equation has no solution because:

5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.

For what value of y does 125=(1/25)^y-1
Alex777 [14]

Answer:y=-1/2

Step-by-step explanation:

125=(1/25)^(y-1)

5^3=(5^(-2))^(y-1)

5^3=5^(-2(y-1))

The same base eliminate each other we then have

3=-2(y-1)

3=-2y+2

Collect like terms

2y=2-3

2y=-1

Divide both sides by 2

2y/2=-1/2

y=-1/2

Marci bought 4 yards of ribbon for $6 how much should marci expect to pay for 10 yards of the ribbon?
Vinvika [58]
Ok, let's find how much does 1 yard of ribbon cost. Let's divide!

6 / 4 = 1.5

Each yard costs $1.50, so let's multiply that by 101.5 * 10 = 15

Marci will pay $15 for 10 yards of the ribbon.
