Answer:
x = 13°
Step-by-step explanation:
5x+15°=7x-11°
5x-7x = -11°-15°
-2x = -26° divide both sides by -2
x = 13°
5x+15° = 5×13°+15° = 80°
7x-11° = 7×13° -11°. = 80°
1500 pounds. 1 ton is equal to 2000 pounds. Divide 2000 by 4 and get 500 multiply by 3 to create 3/4 of a ton and get 1500. 1500 pounds
To get the answer, divide 1 by 8
