Answer: D
Step-by-step explanation:
Just do 7 x 88 LOL
Let's make things easier by simplifying things.
y = 8 and x = 3 is more likely to be understood as a ratio. So for the rest of the answer, their relationship would be represented as y:x
Thus: y:x = 8:3
The problem would be finding y when x = 45
Let us proceed on using the previous equation and substitute x with 45 which would look like this:
y:45 = 8:3
Ratios can also be expressed as fractions which would make things more understandable and easy to solve. So the new form of our equation would be like this:
y/45 = 8/3
Then we proceed with a cross multiplication where the equation becomes like as what is shown below:
3y = 45 * 8
From there, you can solve it by multiplying 45 and 8 then dividing the product with 3 to get y
3y = 360
y = 120
Another way of looking at the problem, especially problems like these, is to take the whole question or statement as an equation. it would probably look like this:
y = 8 when x = 3 : y = ? when x = 45
This would make you understand what approach you can use to solve the given problem.
Answer:
divide it using a calculator
F + 3pi = 7pi
F + 3pi - 3pi = 7pi - 3pi
Combine like terms (3pi + - 3pi = 0)
F = 7pi - 3pi
F = 4pi
The answer is 4pi
20%
7/35 = 1/5 when simplified all the way
1/5 = 20%
