The sum of two-fifths and f is 1/2

The sum of two-fifths and f is 1/2 can be represented by:

2/5+f=1/2

Then to solve for f an easier way would be turn the fractions into decimals to get:

0.4+f=0.5 (subtract 0.4 from both sides)

f=0.1 or 1/10

Hope this helps ;)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
