Answer:
x=2
Step-by-step explanation:
First use the distributive property on the right side... You should get then have 7x+30 = 2 + 6x + 30
Simplify further by combining like terms to get 7x + 30 = 32 + 6x
Now subtract 6x on both sides (6x - 6x cancels out) to get 1x + 30 = 32
Next subtract 30 from both sides(30-30 cancels out) to get 1x = 2
2 divided by 1 is 2 so x = 2
To set this up you need to create the equation, the total cost is $22.69, so that will be on one side of the equation. The other side will be the flat rate 3, plus the 11 cents per minute.
22.69 = 0.11x +3
To solve this we need to subtract 3 from both sides, and then divide the total by 0.11 to get x alone:
22.69 = 0.11x +3
19.69 = 0.11x
x =179
So David rode the ride for 179 minutes. (Dividing by 60 will give you the number of hours since there is 60 minutes in 1 hour. So it’s about 3 hours.)
