Answer:
105:175
Step-by-step explanation:
3+5 = 8
3/8 of 280 is 105.
5/8 of 280 is 175.
the ratio is 105:175
next we have to simplify it:
divide both sides by 5:
21:35 divide both sides by 7=
3:5
Answer: y=(x-1)/2
Step-by-step explanation:
To find the inverse, you want to switch the y with x and x with y. Then, you solve.
y=2x+1 [switch y with x and x with y]
x=2y+1 [subtract both sides by 1]
x-1=2y [divide both sides by 2]
(x-1)/2=y
Now, we know that y=(x-1)/2 is the inverse.
