Answer:

Step-by-step explanation:

It says he walked 2(3/4) miles in 2 hours, and it wants to know how far he walked in 1 mile, which would be that number divided by 2.

2(3/4) is the same as 2.75

2.75/2=11/8

which is equivalent to 1(3/8) miles

Answer:

1 3/8

Step-by-step explanation:

Double the denominator and numerator to make the numerator even, then divide the numerator by 2 while not changing the denominator any further. This gives you 1 and 3 eighths. Half of 2 is one, so you combine these to get 1 & 3/8

Keith earns $43.00 in 4 hours. how much will he earn in 11 hours

PolarNik [594]

You have to divide $43 by 4 to get the hourly rate. After the math is done, we know that Keith earns $10.25 per hour. Now you have to mulitiply $10.25 by 11 (since you want to know how much Keith get in 11 hours) which would give you $118.25 in 11 hours. YOU'RE WELCOME :D

Answer:

y = 5

Step-by-step explanation:

Expand the logarithm:

$\log_y{(5)}+\log_y{(y)}=2\\\\\dfrac{\log{(5)}}{\log{(y)}}+1=2 \quad\text{change of base formula}\\\\\dfrac{\log{(5)}}{\log{(y)}}=1 \quad\text{subtract 1}\\\\\log{(5)}=\log{(y)} \quad\text{multiply by log(y)}\\\\5=y \quad\text{take the anti-log}$
