Answer:
9. y=9h+4
10. y=5r+10
11. y=4x+8
12. y=4n+9
Step-by-step explanation:
9. He gets 9 dollars per hour (h), and 4 dollars extra for gas.
So 9 dollars per hour plus 4 dollars for the gas
y=9h+4
10. Roses (r) are selling for 5 dollars each and there is a delivery fee of 10 dollars.
So 5 dollars per rose plus 10 dollar fee
y=5r+10
11. The tree increases by 4 feet per year (x), and it is already 8 feet tall.
So 4 feet per year plus 8 feet
y=4x+8
12. Each trophy (n) weighs 4 kilograms, and the box itself weighs 9 kilograms.
So 4 kilograms per trophy plus 9 kilograms for the box.
y=4n+9
Tax is money people and businesses pay to the Australian Government to provide services including: health. education. defence.

Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .
Suppose J, K, L, M, N are points on the same line.
MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14
Since LK = MK and LK = 7x - 10, then
7x - 10 = 8x - 14
8x - 7x = -10 + 14
x = 4
LJ = MK + KJ
MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18
LJ = 18 + 28 = 46
