ANSWER QUICKLY PLEASE.Which of the following equations is equivalent to 1.43p + 2.2 = -4.001?


1430p + 2200 = -4001


143p + 220 = -4001


143p + 22 = -4001


143p + 220 = -4001

Answer 1

Answer:

Option 1: 1430p + 2200 = -4001

Step-by-step explanation:

Given that:

1.43p + 2.2 = -4.001

We can replace:

1.43p by 1430p * 10^-3

2.2 by 2200 * 10^-3

-4.001 by -4001* 10^-3

So the equation will become:

1430p * 10^-3 + 2200* 10^-3 = -4001 * 10^-3

Taking  10^-3 common from both side

(1430p + 2200)* 10^-3 = -4001 * 10^-3

Cancelling  10^-3 from both sides we get:

1430p + 2200 = -4001
