2a + 3p = 1.59

a = 0.24

Plug it in our equation:

2(0.24) + 3p = 1.59

Multiply:

0.48 + 3p = 1.59

Subtract 0.48 to both sides:

3p = 1.11

Divide 3 to both sides:

p = 0.37

the temperatures on mercury range from -279°f too 800°F . What Is the difference between the highest and lowest temperatures
QveST [7]
Hello, your answer is: <span>1079, because remember, this equation represents
*800 - (-279)
so, you need to use the method of KCC, or, k=keep, c=change, c=change.
you keep the 800 positive, switch the (-) subtraction sign to a (+) addition sign, and also, make the (-279) a positive 279. so you turn out with:
*800 + 279, which equals = 1079
