Answer:
100
Step-by-step explanation:
100% of a number + 30% of a number is 130% of a number.
This means 130 = 1.3x.
Now we simplify:
130=1.3x
/1.3 /1.3
100=x
x=100
Therefore, the number is 100.
The slope is zero because the line is not moving
To convert any decimal number into a fraction simply divide it by 1 and follow it with as many zeros as there are numbers after the decimal point.
In this case we will divide 0.725 by 1000 (three digits <725> after the decimal point)
0.725÷1000 = 5/8
if for example you had 0.75 and had to convert it into fractions, you would divide it by 100 (because only two digits after the decimal point)
Answer:
6 hours and 20 minutes
Step-by-step explanation:
You will need to use FOIL for this, or distribute.
So you will multiply -7y and 5y, then -7y and 3
Multiply 2 and 5y, then 2 and 3
You will get: -35y²-21+10y+6
Combine like terms:
-35y²+10y-15
There you go!
