alright so you need to find the unit rate for both of these bought items.
5.25(5 1/4) pounds is equal to $2.10 if you set it into an equation
5.25x = $2.10
x represents how much is the price for one pound of banana
to find x you divide $2.10 by 5.25
you can either plug that into a calculator (.4 is the answer)
to divide a fraction
2.10 / 1 ÷ 21/4
switch the 21/4
2.10/1 ÷ 4/21
instead of using division to solve this you actually multiply!(don't ask me why)
2.10 × 4 = 8.4
21 × 1 = 21
now divide 8.4 by 21 = $0.4 for each pound of bananas
do the same on the other persons payment
3.25x = 6.5
x = 0.5
now you answer it. which one is cheaper?
I believe that the correct answer is 12
The formula is V= l × w × h or length times width times height.
V= 45×25×60 so the answer is 67,500 but make sure you put units in your answer!
Hope this helps!
Answer:
(x - 5i)(x + 5i)
Step-by-step explanation:
Find the roots by solving x² + 25 = 0
hence x² = - 25 ( take the square root of both sides )
x = ± 5i
x² + 25 = (x - 5i)(x + 5i)
