0.75 x 500 is 375 of gold in 500 kg of ore
Answer:
74
Step-by-step explanation:
(8x10) - 6 =
80 - 6 = 74
8.7/2=q/4
multiply both sides by 4: q=8.7/2*4
multiply both sides by 2: 2q=8.7 times 4
refine the equation: 2q=34.8
multiply both sides by 10: 20q=348
Divide both sides by 20: 20q/20=348/20
refine the equation for the final answer: q=87/5
