Answer:
x=1
Step-by-step explanation:
3^ (3x+1) = 81
Rewrite 81 as a power of 3
3^4
3^ (3x+1) = 3^4
Since the bases are the same, the powers are the same
3x+1 =4
Subtract 1 from each side
3x+1-1 =4-1
3x=3
Divide by 3
3x/3 = 3/3
x =1
To solve this equation we must use division.
We know we spent 24.32 to fill the gas tank.
And each gallon cost 1.90
We can divide and solve for how many gallons he bought.
24.32 ÷ 1.90 = 12.8
Todd has bought 12.8 gallons of gas.
Good Luck! <3
