Answer:
0.8
Step-by-step explanation:
20 / 100 = 0.2
1 - 0.2 = 0.8
8 printers for $145 each is a total of $1160.
3 laptops for $439 is a total of $1317.
Therefore, the price of 3 laptops for $439 each cost more than 8 printers for $145 each.
45 - 35 = 10
so we divide by 4 10/4 = 2.5
The sequence is 35, 37.5, 40, 42.5, 45
2.750 + 0.003 + 0.158
= 2.753 + 0.158

3) y^2 - 1 = 24
add 1 to each side:
y^2 = 25
Take square root of each side: y = √25
y = 5 or -5
4) y^2 - 1 =48
Add 1 to each side:
y^2 = 49
Take square root of each side:
y = 7 or -7
