Answer:
1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x
2. +3a+2a also equals +5a
3. - 5 is left alone and there is no other similar expression
Put them together the answer becomes
-3x+5a-5
It doesn't have to be the same order of format but the numbers must be as such
Answer:
1 1/4
Step-by-step explanation:

five eighths plus five eighths equals ten eighths simplified to one and two eighths and simplified again to one and one fourth.
to vertically shrink a function by a factor of c, multiply the whole function by c
f(x) vertically shrunk by a factor of c would be cf(x)
so f(x)=-3|x-4| vertically shrunk by a factor of 1/2 would be
If he saves $ 8 each week...and his mom is giving him 0.25 for each dollar, then he will have (8 + 0.25(8)) = 8 + 2 = $ 10 per week
10w = 100.....with w being the number of weeks
w = 100/10
w = 10...so he will have it in 10 weeks <==
Combine like terms first.
4b2+2b2-b2= 5b2
5b2 +5
5 x 5^2+5
5 x 25 + 5
125+5
130
