To solve his equation start by finding how many gallons of gas you need to purchase for the total trip.
Set up an expression that divides the total distance of the trip by the miles received per gallon.
This gives you:
400 / 35
Divide to get 11.43 gallons.
To find the cost of this, multiply the total number of gallons needed to cover the trip by the cost of each gallon.
Set this up in another expression.
This results in:
11.43 x 3.30
Multiply the values to find the total cost.
This leaves you with:
37.72
So, the total cost for gas for a 400 mile trip on 35 miles per gallon is $37.72.
I hope this is correct and helps you! :)
Answer:
Step-by-step explanation
S.P of a t.v = rs 7200
Loss % = 25%
Therefore, C.P = S.P (100/100-loss)
=7200(100/100-25)
=7200 x 100/75
=9600
So,now C.P = 9600
Profit% = 25%
Therefore, S.P = C.P (100+profit/100)
=9600(100+25/100)
=9600 x 125/100
=12000
So,the price he should sell to gain 25%
=12000
Hope it helps...!!!
Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
