Step-by-step explanation:
8)
describe y in terms of x
y=5+x
so now replace y with terms of x
5+x+3x=37
4x=32
x=8
y=13
9)
do the same here
x=y+1
2y+x=19
2y+y+1=19
3y=18
x=6
y=7
All we have to do here is divide $110 by $2.75
This will give us the amount of days you can buy lunch with $110
110 ÷ 2.75 = 40
Therefore, it will take 40 days to spend all the money in the account
Hope this helps you

Kilometres when Satish is alone
150 kilometres in the beginning
150 kilometres in the end
Total: 300 kilometres
Litres of gas when Satish is alone
6 litres of gas per 100 kilometres

$1.2 per litre
18 x 1.2 = $21.6
Therefore, Satish will pay $21.6 for gas.
