Ni because if you divide or mulriply the denominator you have to multiply or divide the numerator by the same amount. It is not possible dince you can divide the denominator by 2 to get 3 but you cant divude 5 by 2 and get an evn number

It depends on the size of Mountain Dew bottles! It differs whether it is a 12 oz or a 16 oz bottle. I need more information to solve it.
Answer:
y = 28 degrees
x = 28 degrees
Step-by-step explanation:
A right angle = 90 degrees
90 degrees - 62 degrees = 28 degrees
This is for both x and y because 62 degrees occupies both the right angles.
Answer:
1 kg of 30% gold and 3 kg of 10% gold
Step-by-step explanation:
Let us take "x" kg of 30% gold, and
"y" kg of 10% gold
We need to make 4 kg of 15% gold, that would be:
4(15%) = 4 (15/100) = 4(0.15) = 0.6kg
We can now write an equation as:
30%x + 10%y = 4(0.15)
0.3x + 0.1y = 0.6 <u>(equation 1)</u>
Also, we know there will be 4 kg from "x" and "y", so we can write:
x + y = 4
or x = 4 - y
We substitute this into equation 1 and solve for y first:
0.3x + 0.1y = 0.6
0.3(4 - y) + 0.1y = 0.6
1.2 - 0.3y + 0.1y = 0.6
0.2y = 0.6
y = 3
And x = 4 - y, x = 4 - 3 = 1
So,
1 kg of 30% gold and 3 kg of 10% gold
