The answer is 9
both 81 and 63 are dividable by 9, and nothing higher
So what you do is go 5(3y+5)-4y=14 which equals 15y+25-4y=14 which turns into 11y+25=14 than you move the 25 over which equals 11y=-11 so y=-1 then you enter -1 in for y which looks like 5x-4(-1)=14 than you solve that which is 5x+4=14 than you move the 4 over and you get 5x=10 than x=2
x=2
y=-1
80 multiplied by 0.6 = 48
80-48=32
Answer=32 Books are nonfiction
Answer:
Solution:
Given, cost price = $784.50
Profit = 6.5% of cost price
= 6.5/100 × $784.50
= $50.9925 [since, profit% is always on C.P.]
And selling price = cost price + profit
= $784.50 + $50.9925
= $835.4925
Hence, selling price = $835.4925
