Answer:

x=1

Step-by-step explanation:

First find a common denominator between 7 and 4 which is 28, Multiply both equations by 28 eliminating the denominators so now you have theses two equations: 4(2x + 12) = 7(3x + 5) distribute these equations to get:

8x + 48 = 21x +35 now you want to get the x's on one side so 8-21 = -13 which as an equation so far would be -13x + 48 = 35 now do 35-48 = -13 so you can have 13x alone on one side. Your final equation now before you solve is

-13x = -13 the divide -13 by -13 to get 1.

Hope this helps you understand it better

Answer:

d) 10

Step-by-step explanation:

x ÷ \frac{1}{2}  + 8 = 13

substitute 10 for x:

⇒ 10 ÷ \frac{1}{2}  + 8 = 13

solve:

1) divide 10 by \frac{1}{2}

⇒ 10 ÷ \frac{1}{2}  = 5

2) add 8 to 5

⇒ 8 + 5 = 13

You have recorded your car mileage and gasoline use for 5 weeks. Estimate the number of miles you can drive on a full 15-gallon
I am Lyosha [343]

Answer:

325 miles to the nearest mile.

Step-by-step explanation:

Average  gasoline consumption over the 5 weeks

= miles travelled / gasoline used

= (198 + 115 + 154 + 160 + 132) / (9 + 5 + 7 + 8 + 6)

= 21.69 miles per gallon.

Estimate of number of miles you can drive on 15 gallons

= 15 * 21.69

= 325 miles.
