2. One solution
Step-by-step explanation:
1. 7^2-5*(-4)*8 > 0 (is a number +)
2. Is (x-5)^2=0 ---> x=5
Answer:
x=25
Step-by-step explanation:
x+y=100 (y being number of 8¢ stamps)
12x+ 8y = 900
-----------------------------------
y = 100-x
12x + 8y = 900
----------------------------------------
12x + 8(100-x) = 900
12x + 800 - 8x = 900
12x - 8x = 900 - 800
4x = 100
x=25
