A) 2L + 2W = 48
B) L * W = 140
B) W = 140 / L
Inputting this to equation A)
A) 2L + 2*(140 /L) = 48
L + 140/L = 24
Multiplying both sides by "L"
L² + 140 = 24L
L² -24L +140 = 0
(L -10) * (L-14) = 0
L= 10
L = 14
If length = 10 then width =14
If length = 14 then width = 10
Okay so 123-45-67+89=100
That should be the answer
Answer:
Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16
Step-by-step explanation:
Let the number he gave to Alaina be x. Now, we know he gave twice as many to Miguel. Amount received by Miguel is 2x.
He gave Kira 2 times what he gave Miguel, that is 2x * 2 = 4x
Addition of all these equals 28. We now get x
4x + 2x + x = 28
7x = 28
X = 28/7
x = 4
Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16
4 goes in the blank.
In math, if any number like that is 5 or higher, it rounds to the nearest tenth.
so for example, 4 would round down to 0, and 5 would round up to 10.
So with the 4, it Makes 149.6k, which rounds down to 100,000.
In multiplying fractions, you multiply the numerators and denominators.
51 / 2 * 21 / 3
can be reduced as
(17 / 2) * (21 / 1)
357 / 2 --> This is the answer based on the given.
Assume that its a mixed fraction:
5 1/2 * 2 1/3
11/2 * 7/3
= 77 /6
