Answer:
B
Step-by-step explanation:
3(2+x)
distribute
=6+3x
First we write it into scientific notation which is 3.5*10^7. now it's order of magnitude is power of 10 that is 7. So order is 7.
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
