10 time the value of the digits to the right.
Answer:
e = 7.5
Step-by-step explanation:
Hi,
15 = e/0.5
You need to find what e equals. To do that, you need e all by itself. So to get e by itself in this equation, you need to multiply by 1/2 (same thing as 0.5). 15 x 0.5 is equal to 7.5.
To check your work, 7.5/0.5 is equal to 15.
So you know it's correct.
I hope this helps you :)
Answer:
Add 1 to each side
Multiply each side by 4
Take the square root of each side
Subtract 5 from each side
Combine terms
Step-by-step explanation:
1/4(x+5)^2-1=3
Add 1 to each side
1/4(x+5)^2-1+1=3+1
1/4(x+5)^2=4
Multiply each side by 4
4*1/4(x+5)^2=4*4
(x+5)^2=16
Take the square root of each side
sqrt((x+5)^2)=±sqrt(16)
x+5 = ±4
Subtract 5 from each side
x+5-5 = -5 ±4
x = -5 ±4
Combine terms
x = -5+4 x = -5-4
x = -1 x = -9
For the rate of 25 pieces and hour it will take 7 hours.
500 - 325 = 175
175 ÷ 25 = 7
7 hours
