Answer:
Step-by-step explanation:
P = 8x + 20
4*side = 8x + 20
side = (8x + 20)/4
= 8x/4 + 20/4
side = 2x + 5
A. 48 / 12 = 4 24 / 6=4 Factory A should work 4 hours.
B. 48 / 8 = 6 24 / 4 = 6 Factory B should work 6 hours.
Hope this helps!
Answer:
A) R = P/I²
Step-by-step explanation:
I = √P/R
Square each side
I^2 = (√P/R)^2
I^2 = P/R
Multiply each side by R
I^2R =P/R * R
I^2R = P
Divide by I^2
I^2R / I^2 = P/ I^2
R = P/ I^2
Answer: Todd earned $40 mowing the neighbor's lawn.
Step-by-step explanation:
Let x represent the amount of money that Todd earned, mowing his neighbor's lawn.
He spent one-fourth of his money see a movie. It means that the amount spent in seeing a movie is x/4
Then he spent $6.00 on popcorn and drinks. It means that the total amount spent is
x/4 + 6
The amount left would be
x - (x/4 + 6) = x - x/4 - 6
When he went home, he had $24.00 left. It means that
x - x/4 - 6 = 24
x - x/4 = 24 + 6
x - x/4 = 30
Cross multiplying by 4, it becomes
4x - x = 120
3x = 120
x = 120/3
x = $40
To make calculation easier, we first multiply
1.35 × 100 = 135
then we need to find how many groups of 5 are there in 135.
to do so, we simply take
135 ÷ 5 = 27
therefore, the answer is <u>27.</u>
