or,
15
100
× x = 42
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 42 ×
100
15
x = 280
If you are using a calculator, simply enter 42×100÷15, which will give you the answer.
If you’re talking about answers a would be the option first b would be 2nd and c would be 3rd
Substitute the x with 5
-(5)2 + 4(5) - 10 = 0
Answer:
