sorry I don't know the answer but i hope you get well soon
Answer:
first deal with g(-1)
y=4a - 3
a=4y -3 and now make y the subject again
a+3/4...now put it into f(a)
2(a +3/4) simplyifying
a+3/2 as yo final ans
40/15=64/q
The answer is q=24
First, let's see what the answer is when we follow this equation using PEMDAS.
5 + 4 x 2 + 6 - 2 x 2 - 1
5 + 8 + 6 - 4 - 1
14
Now, let's trying grouping 5 + 4 together, and solving it again.
(5 + 4) x 2 + 6 - 2 x 2 - 1
9 x 2 + 6 - 2 x 2 - 1
18 + 6 - 4 - 1
24 - 5
19
So, the parentheses go around 5 + 4 to get your answer!
300 x 5%
= 300 x 0.05
= 3 x 5
= 15

Hope it helped! :-D
