F(x2-5)=4x2-19 is the answer
Add all of the numbers together (a), and then add the two numbers for large (b). divide b by a, and round the first 3 numbers of the decimal to the nearest hundredth.
A. This is the original equation: 2x + 3 - 1 = x + 5
b. 2x + 2 = x + 5 ← combined like terms on left side
2x + 2 - 2 = x + 5 - 2 ← used inverse operation to collect constants on right side
2x = x + 3 ←simplified each side
2x - x = x - x + 3 ←used inverse operation to collect variable terms on left side
x = 3 ← simplified each side
answer x = 3
c. 2(3) + 3 - 1 = 3 + 5
6 + 3 - 1 = 8
9 - 1 = 8
8 = 8
Answer:
80% of $200 would be $160
3 hours x $3 = $9 for working 3 hours
$12 + $5 + $7 = $24 in tips
$9 + $24 = $33 total money earned
