N₁*$0.10 + n₂*$0.25 = $2.25
n₁ + n₂ = 12
-----------
This means that:
n₁ = 12 - n₂
And:
(12 - n₂)*$0.10 + n₂*$0.25 = $2.25
12*$0.10 - n₂*$0.10 + n₂*$0.25 = $2.25
$1.20 + n₂*$0.05*(5-2) = $2.25
$1.20 + n₂*$0.05*3 = $2.25
$1.20 + n₂*$0.15 = $2.25
n₂*$0.15 = $2.25 - $1.20
n₂*$0.15 = $1.05
n₂ = ($1.05)/($0.15)
n₂ = 7
If n₂ = 7:
n₁ + 7 = 12
Therefore, n₁ = 5.

Answer: 183.33
Step-by-step explanation:
We have, 60% × x = 110
or,
60
100
× x = 110
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 110 ×
100
60
x = 183.33
If you are using a calculator, simply enter 110×100÷60, which will give you the answer.
Answer:
6 bows
Step-by-step explanation:
First find a common denominator. In this case, it would be eight. So now you would multiply your numerator by however much you multiplies your denominator.
3/4 would become 6/8.
6/8 divided by 1/8 is 6.
