Answer:
9.8 X 10^-07
Step-by-step explanation:
When you have a number like that then you move the decimal how many time you can to the right so it can be a single digit and remember this when you have scientific notation then the number cant go past 10 and it cant go below 0.
For Problem #2, the second one should be 6x+4x+12, and the third one should be 10x+12
<h3><u>Fraction to Decimal:</u></h3>
Divide the numerator (upper number) by the denominator (bottom number) on your calculator. Whatever number you get would be your decimal.
<h3><u>Decimal to Percent:</u></h3>
Take your decimal and use your calculator to multiply it by 100. Whatever number you get would be your percent. However, since it is a percent, you need to include the percentage unit.
<h3><u>Demonstration:</u></h3>
1/4 = 0.25
0.25 * 100(%) = 25%
Answer:
$17.85
Step-by-step explanation:
Let the dollar amount per shirt be represented by s.
Let the dollar amount per pants be represented by p.
You have the following system:
3s+2p=104.81
2s+1p=61.33
If I multiply the bottom equation by -2, I can set the system up for elimination since the equations are already and the same form and I will have 2p and -2p in the same column there. 2p+(-2p)=0
Multiplying equation 2 by -2:
3s+2p=104.81
-4s-2p=-122.66
-----------------------Add the equations:
-1s =-17.85
Multiply both sides by -1:
s=17.85
So one shirt cost $17.85
