roys car gets an average gas mileage of 29mi/gal. Roy starts his trip with 12 gal of gas.How many gallons of gas are left after a 140 mile trip?(only an algebraic solution can receive full credit)
2 answers:
The answer is 208. The equation to get this is m=29g-140 where m is miles and g is the gallons. Plug 12 in for g and solve for m. 29 * 12 = 348, 348-140 = 208. Therefore, m=208.
You can use a ratio to solve this. 29/1 = 140/x Cross multiply 29x = 140 x = about 4.8 gallons after the trip

<h2>Therefore, d = 3.</h2>
That is 3 slots 12 in 1st slot 11 in 2nd 10 in 3rd so that is 12*11*10 or 1320 ways
Y=1/2x+7 because you flip the sign and the numbers on the fraction for the slope then solve for the y-not
3(4x-5)+4(2x+6) Distribute. 12x-15+8x+24 12x+8x= 20x 24-15= 9 20x+9 <---- simplified expression I hope this helps! ~kaikers
