Answer : 2 2/15
To begin you need to convert the fractions into something they both can go into. Sometimes it is easier to multiple the two denominator of the fractions, which in this case it is.
So, 3 times 5 is 15
This means your going to convert your fraction into 15th
1/3 is 5/15
This is because you need to times the bottom by 5 in order to get 15, so you need to do the same with the top.
1/5 is 3/15
This is because you need to times the bottom by 3 to get 15 so you do the same with the top
Next you just subtract the amounts separately
4-2 = 2
5/15 - 3/15 = 2/15
This means your answer is 2 2/15
6 - a =

(9a - 18)
First, simplify

to

/ Your problem should look like:
Second, multiply both sides by 3. / Your problem should look like:
Third, expand. / Your problem should look like:
Fourth, add 3a to both sides. / Your problem should look like:
Fifth, simplify 9a - 18 + 3a to 12a - 18. / Your problem should look like:
Sixth, add 18 to both sides. / Your problem should look like:
Seventh, add 18 + 18 to get 36. / Your problem should look like:
Eighth, divide both sides by 12. / Your problem should look like:
Ninth, since 3 goes into 12 to get 36, simplify

to 3. / Your problem should look like:
Tenth, switch sides. / Your problem should look like:

Answer:
a = 3 (one solution)
Answer:
scale factor: 1.16
perimeters: 21.84 ft and 25.36 ft
M = 9
o = 7
m + 0 = 9 + 7 = 16
Hence, the answer is 16.
Answer:
B. (0,0)
Step-by-step explanation:
The y-intercept of the equation f(x) = 1/2x lies on the y-axis.
This means we need to set x = 0 and solve for y
1/2(0) = 0
Therefore, (0,0) is the y-intercept of this equation.
