What is the combined length of all the buttons longer than 1 inch?

2 1/2 inches

Explanation:

There are two marks on the line plot above 1 inch; both are on 1 1/4 inches.  This means to find the total length we add together

1 1/4 + 1 1/4

They already have a common denominator; this means we add the whole numbers then add the numerators.

1+1 = 2; 1/4 + 1/4 = 2/4

This gives us 2 2/4.  The fraction will simplify to 1/2; this gives us 2 1/2.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
