Answer with Step-by-step explanation:
We are given a variable b
We have to state the additive property of zero using the variable b.
Additive property of zero: It states that when any number b is added to zero then we get sum is equal to number itself.
Mathematical representation:

Suppose, a number b=9
Then, 9+0=9
0+9=9
This property is called additive property of zero because when 9 is added to 0 then we get sum equals to 9.
Answer:
30-2x
Step-by-step explanation:
yuson has to finish am total of 30 hours in community service
she does 2 hours each day
in x days, hour of service done=2x
after x days hours of service left=30-2x
therefore the linear equation representing the hours yuson has left after x days is:
30-2x
11 as many fiction books as non fiction.
Fiction books F, Non Fiction NF
F: NF = 11 : 1
Total ratio 11+ 1 = 12.
Fraction of Fiction books F, = 11/12
Total books = 312.
Fiction books = 11/12 * 312 = 286
Fiction books = 286
Simply put,
If you find a common denominator between 12 and 16, and multiply them to fit,
You should end up with a proportion giving you the correct answer. Whichever is lower is the better deal
Ex: a box of cereal from target costs $2
Two box deal from Costco costs $5
Which is cheaper for the money.
Assuming they are the same size, all you have to do is take the dollar amount from the one from target and multiply it by two, giving you the cost of two boxes.
$4<$5
Answer:
The total fish is 65
(PLEASE MARK BRAINLIEST)
Explanation:
65 x 0.80 = 52
Therefore, that shows that 80 percent is equal to 52 fish, and there are 13 remaining fish that are not freshwater.
