Answer:
n+16
Step-by-step explanation:
21+(n-5)=21+n-5=n+21-5=n+16
Percent problems can be solved by writing equations. An equation uses an equal sign (= ) to show that two mathematical expressions have the same value. Percents are fractions, and just like fractions, when finding a percent (or fraction, or portion) of another amount, you multiply. ... Percent of the Base is the Amount.
12 x 5.2
Estimate:
since 5.2 is about 5, we can estimate this to:
12 x 5 = 60
Find the Product:
12
<u> x 5.2
</u> 2 4
<u> + 6 0 0
</u> 6 2 4
now add the decimal back in. In the original problem there is one decimal place (the .2 in 5.2) so we move the decimal place one over in our product
624 becomes 62.4
