Total weight of the gravel, in tons used for the driveway is 8.6 tons
Weight of first load = 8 tons
Weight of second load = 1200 pounds
Convert pounds to tons:
1 pound = 0.0005 ton
1200 pounds = 0.6 ton
Then,
Weight of second load = 0.6 ton
Total weight of the gravel, in tons = Weight of first load + Weight of second load
= 8 tons + 0.6 tons
= 8.6 tons

Answer:
x=2.2582, y=19.91/9. (2.2582, 19.91/9).
Step-by-step explanation:
5x+4y=20.14
6x+7y=28.15
-------------------
6(5x+4y)=6(20.14)
-5(6x+7y)=-5(28.15)
------------------------------
30x+24y=120.84
-30x-35y=-140.75
--------------------------
-9y=-19.91
9y=19.91
y=19.91/9
5x+4(19.91/9)=20.14
5x+79.64/9=20.14
5x=20.14-79.64/9
5x=11.291
x=11.291/5
x=2.2582
