So basically, think of a ratio as a fraction for these problems. You see the 2 numbers and you put the first one as the numerator and the second as your denominator. For example:
5 to 10
We would change this into:
Because the problem says to simplify, we can divide both sides by 5 and simplify it into:
If the problem says 5:10 instead of "5 to 10" it's the same problem just with different wording. If the numbers are labeled, the you can write the labels next to the number it corresponds with.
If you have any questions, feel free to ask down in the comments, I'll be happy to work with you!
F(1) + g(2) = (2*1 - 5) + |(-3)*2 - 1| = -3 + 7 = 4
[Where * represents multiplication.]
A yard is equal to 3 feet. So knowing this we multiply 5280 which is how many feet are in a mile by 2.5 that is the miles we will take into consideration.
5280 x 2.5= 13,200
Now this value we divide it by 3 which is how long a yard is in terms of ft measurement.
You can make the first equation equal to x: x=0.5y+5 and substitute it into the second equation: 2(0.5x+5)-2y=4 -> -y+10=4 so y=6.
Then plug y into either equation: 2x-(6)=10 -> x=8
The correct ordered pair is (8,6)
