Step-by-step explanation:
8x−5y=11 = Let's solve for x.
8x−5y=11
Step 1: Add 5y to both sides.
8x−5y+5y=11+5y
8x=5y+11
Step 2: Divide both sides by 8.
8x

=
5y+11

4x−3y=5= Let's solve for x.
4x−3y=5
Step 1: Add 3y to both sides.
4x−3y+3y=5+3y
4x=3y+5
Step 2: Divide both sides by 4.

Answer:
$18.00
Step-by-step explanation:
Start by working out 10%, that's easy:
15 ÷ 10 = 1.5
That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:
1.50 x 2 = 3
A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00

Answer:
C
Step-by-step explanation:
You have to do change of y over change of x, substitute the numbers to get 0.30-0.90 for y then 1-3 for x, get -0.06/-2 and solve that to get 0.3 per pound per year, which is answer C
