Answer:
Step-by-step explanation:
1.)
10p² - 7 = 243
10p² = 250
p² = 25
p = ±5 (meaning p can both equal -5,5)
2.)
9b²+9 = 684
9b² = 675
b² = 75
b = ±√75
= ± 5√3
Answer:
3 + -5 = -2 because adding a negative is basically subtracting.
So 3 + -5 = 3 - 5 = -2

Percent increase=(difference in price/original price)×100
=((2075-1195)/1195)×100
=(880/1195)×100
=(176/239)×100≈74%
Find what 30% of 2075
Part/whole=%/100
x/2075=30/100
100x=(30)(2075)
100x=62250
100/100x=62250/100
x=622.50
Subtract the 30% from 2075 to find price.
2075-622.50=$1452.50
