e= 10h+5
Step-by-step explanation:
h is no of hours
e is earnings
8(2x - 3)-6x
First, replace all the x's with 3s. Simplfy 2 × 3 to 6. / Your problem should look like: 8 × (6 - 3) - 6 × 3
Second, simplify 6 - 3 to 3. / Your problem should look like: 8 × 3 - 6 × 3
Third, simplify 8 × 3 to 24. / Your problem should look like: 24 - 6 × 3
Fourth, simplify 6 × 3 to 18. / Your problem should look like: 24 - 18
Fifth, simplify 24 - 18 to get 6. / Your problem should look like: 6
Answer: 6

<u><em>The complete question is</em></u>
Suppose that a new fuel-efficient European car travels an average of 28 kilometers on 1 liter of gasoline. If gasoline costs 1.50 euros per liter, how much will it cost to drive 220 kilometers ?
step 1
using proportion
Find out the number of liters of gasoline needed for 220 kilometers
so

step 2
Find the cost to drive 220 kilometers
Multiply the cost of one liter of gasoline by the total liters of gasoline needed to travel 220 Km
so

A ?

Answer:
80 units
Step-by-step explanation:
KN = MN
9x - 5 = 7x + 7
2x = 12
x = 6
KM = 2KL
KM = 2(6x + 4)
KM = 12x + 8
KM = 12(6) + 8
KM = 80
