Answer:
Step-by-step explanation:
Let's take it part by part.
" lina is 1 year less than..." So this means a value that we get some other way -1. So let's call it x-1 for now. The next part tells us how to get x.
"3 times his age" so now we have 3y-1, where y is Adam's age. We know adam's age though.
3*2 - 1
6-1
5
Answer:
Step-by-step explanation:
6.7 – (-2.5)
2.5+6.7
6.7 + (-2.5)
-2.5+6.7
6.7-2.5
neither
-2.5-6.7
2.5-6.7
-6.7+2.5

You can do this in parts.

g(-3) = 3(-3) + 1 = -9 + 1 = -8
So, 5g(-3) = 5(-8) = -40.
So f(-1) + 5g(-3) = 2 - 40 = -38
Or you can do this as one big chunk.
f(-1) + 5g(-3)
1/10 + 1/10 = 2/10
10 / 5 = 2
3/5 = 6/10
2/10 + 6/10 = 8/10
10/10 - 8/10= 2/10
