5/1
Step-by-step explanation:
3.75 + 2.25 = 5
5 = 5/1
Easy
just remember
you can do ANYTHING to an equaiton as long as you do it to both sides
try to get place holder by itself
4.5b+9=90
minus 90 from both sides
4.5b+9-9=90-9
4.5b+0=81
4.5b=81
either divide both sides by 4.5 or double 4.5 to get rid of the decimal
I will double
double both sides
9b=162
divid both sides by 9
b=18
When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators. Example 1: ... To add the fractions with unlike denominators, rename the fractions with a common denominator.
Answer: Step 2
Step-by-step explanation:
The scale factor is defined as image/preimage, so since the image is circle F and the preimage is circle E, k should be equal to (radius of F)/(radius of E), or 1/2, not 2.
70% = 70/100
divide 70 by 100
=0.7
