How do I use the subtraction theorem to write equivalent expressions?

1 answer:

3 0

The subtraction theorem states that for all real numbers, $a$ and $b$ , $a-b=a+(-b)$ .
(To subtract, we can add the inverse.)
Thus, we can have the these two equivalent expressions.

$3 - 2 = 3 + (-2) = 1\\ \\ 5 - (-2) = 5 + 2 = 7$

What is the square root between which two intergers explain

Softa [21]

Answer:

I’m pretty sure the square root between two Integers is when you have a non perfect square root for example the square root of 92. Since it is not perfect you have to estimate it and you use a numeric line to do it so in this case the square root of 92 would have to go in between the nearest perfect square roots from both sides which are 81 and 100. In the line you would see it as 9 and 10 and you have to estimate the value which in this case would be about 9.6

A pack of cinnamon-scented pencils sells for $5.00. What is the sales tax rate if the total cost of the pencils is $5.20?

Leya [2.2K]

Calculate the percentage increase,work out the difference (increase) between the two numbers you are comparing. Then divide the increase by the original number and multiply the answer by 100.

520-500 = 20
20÷500 =.04
.04 ×100= 4%
