Me, i'm confused with this problem : c! 16 points! you. (view the picture)add − + using the number line. select the location on the number line to plot the sum.

2/5 is the same as 4/10 if you multiply top and bottom by 2

The mixed number 1&3/10 converts to the improper fraction 13/10. You use this formula to convert

a & b/c = (a*c+b)/c

So that means -1&3/10 turns into -13/10.

Now add the fraction -13/10 to 4/10 to get -13/10+4/10 = (-13+4)/10 = -9/10

So the answer as a fraction is -9/10

Note how -4/5 = -8/10 = -0.8 and -9/10 = -0.9

This means that the fraction -9/10 is exactly at the midpoint between the tickmarks "-1" and "-4/5" on the number line.

answer:

3 bags of apples and 2 bags of oranges.

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
