The option (B) 2,-2 is correct because the number satisfy the provided expression.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a number bank shown in the picture.
The problem given:
7 - __ = 7 + __
A. 3,-4
Checking for the above option:
7 - 3 = 7 - 4
4 = 3 (false)
B. 2,-2
Checking for the above option:
7 - 2 = 7 - 2
5 = 5 (true)
O C. 1;-4
Checking for the above option:
7 - 1 = 7 - 4
6 = 3 (false)
D. 2; 3
Checking for the above option:
7 - 2 = 7 + 3
5 = 10 (false)
Thus, the option (B) 2,-2 is correct because the number satisfy the provided expression.

Quadrant General Form of Point in this Quadrant Example
I (+, +) (5, 4)
II (−, +) (−5, 4)
III (−, −) (−5, −4)
IV (+, −) (5, −4)
-2x + 4y = 22
-2x - 3y = 8
Subtract 2nd from 1st equation,
7y = 14
y = 14/7 = 2
Substitute it in 1st equation,
-2x + 4(2) = 22
-2x = 22 - 8
x = -14/2
x = -7
In short, Your Answer would be (-7, 2)
Hope this helps!
Answer:
About 30.98386677 ft above the water.
Step-by-step explanation:
Use pythagorean theorem, a^2+b^2=c^2.
So when you plug in the numbers it would be x^2+22^2=38^2. Move 22^2 to the right side giving you x^2=38^2-22^2. Then subtract and take the square root of x^2.
Answer:
2 1/8 inches from either edge
Step-by-step explanation:
First we have to subtract the computer length from the table length to find how much room there will be left on the table 28 3/4-24 2/4=4 1/4 and now since he wants it in the center we will divide that number by 2 because there will be some room on either side of the computer 4 1/4 divided by 2 is 2 1/8
I hope this helps and please don't hesitate to ask if there is anything still unclear!
