Inverse operationsare pairs of mathematical manipulations in which one operation undoes the action of the other—for example, addition and subtraction, multiplication and division. The inverse of a number usually means its reciprocal, i.e. x - 1 = 1 / x . The product of a number and its inverse (reciprocal) equals 1.

For example for the first one ->
7/10 + 1/2 multiply the numerator and denominator of 1/2 by 10 (the bottom of the other fraction) and you get 10/20. The. The bottom of 1/2 is 2, so 2 times 7/10 is 14/20. So 14/20 + 10/20 is equal to the first one.

Answer:
x < -4

does not
Step-by-step explanation:
Imagine that as x goes toward infinity, the temperature gets warmer, and as x goes toward negative infinity, the temperature gets colder. It says that the daily high temperature is colder than -4, which means that the arrow will point to the left. Since it is colder than -4, -4 is not included, and the point should remain unfilled. Looking back at Charlotte's graph, we can see that it does not accurately represent the problem.

Answers
Answer:
55.6 inches
Step-by-step explanation:
We use the Pythagorean Theorem in this question ~
[tex]a^{2} + b^{2} = c^{2}[/tex]
A = Height (What we are finding in the problem.)
B = Width (77 inches)
C = Diagonal (95 inches)
----------------------------------------------------------------------------------------------------------
a² + (77)² = (95)²
a² + 5929 = 9025
a² = 3096
a = [tex]\sqrt{3096}[/tex] = 55.641710...
Round to the nearest tenth ~
55.641710... ≈ 55.6 inches
a^2 + b^2 = c^2
Plug in the values given
77^2 + b^2 = 95^2
Now we have to change the equation to solves for b (the height)
77^2 - 95^2 = -b^2
Then we solve
5929 - 9025 = -b^2
(-3096 = -b^2)/-1
3096 = b^2
sqrt(3096) = sqrt(b^2)
55.6… = b
The table shows the time it takes jessica to make rubber band bracelets using a loom. Based on the table how many bracelets can jessica make in 4.5 hours

4.5 hours = ?
4.5 hours/× 4 bracelets
_______
1 hour/
4.5×4 bracelets = 18 bracelets
In an hour Jessica makes four bracelets and in 4.5hours she makes how many bracelets ,we don't know , obviously in 4.5hours she would make more so if more less will divide.
so 4.5hours over 1hour times 4 bracelets. so hour will cancel hour and now 4.5 times 4 bracelets is equal to 18 bracelets

A bookstore sells 7 books for $59.50. Which table represents the relationship between number of books and the total price?
Answers
Answer:
The answer is A
Step-by-step explanation:
The answer is A because if you divide 59.50/7 you would get 8.50, and 8.50 x 8 is 68! You can easily eliminate any other answer choices if the distance between the values is not equal!
Answer:
A is the correct answer.
Step-by-step explanation:
If you divide $59.50 by 7 you get 8.5. Which would be $8.50. You can then go through each table and multiply the cost of one book with how many books are being bought. So yeah. Hope this helps
