There is a 6:5 ratio of girls to boys in the junior class.
So you do 90*30=2700 then 7*30=210 then 5*90=450 then 5*7=35 then add all these together 2700+210+450+35=3395 which is 97*35.
Answer:
When you're at the grocery store. For example, you're shopping for paper plates, and the price says they are $4.90, you want to round that to $5 because of tax, and because you don't want to be that person telling the cashier that you don't have enough money.
hope this example is good and helps :)
(mx + 7)(5x + n) = 5mx^2 + mnx + 35x + 7n
= 5mx^2 + (35 + mn)x + 7n
= px^2 + 15x + 14
7n = 14
n = 2
35+mn = 15
35+ m(2) = 15
35+ 2m = 15
2m = 15-35
2m = -20
m = -10
p = 5m
= 5(-10)
=-50
m(n + p) = -10(2 -50)
= 480
Answer:
Step-by-step explanation:
If 15% is paid for, then 100% - 15% = 85% (0.85 in decimal) is not paid for.
