Answer:
X = 7/3y - 10/3
Step-by-step explanation:
Add - 7y to both sides = -3x + 7y = 10 - 7y
= -3x = 10 - 7y
Divide both sides by -3
-3x/-3 = 10/-3 - 7y/-3
x = 7/3y - 10/3
Answer:
There is 25 1/8 inches left
Step-by-step explanation:
We have a board that is 38 3/4 inches
We cut away 13 1/4
38 3/4
-13 1/4
-----------
25 2/4
The saw takes 3/8
25 2/4
- 3/8
-------------
Get a common denominator of 8 2/4 * 2/2 = 4/8
25 4/8
- 3/8
-------------
25 1/8
There is 25 1/8 inches left
The answer is the mean is 8. The range is equal to the largest number, 10 minus the smallest number, 5. It equals 5, so d is wrong. The mean is all of the values added together, 80, divided by the number of values, 10. So, 8. The median is the middle which is between 7 and 8, so 7.5. Five has no dots.
Minus m-n = 36 so 36 is your answer.
Answer:
The value of 
is 10º.
Step-by-step explanation:
From Euclidean Geometry we remember that the sum of internal angles within a triangle equals to 180º. We present the resulting triangle after applying some geometric handling in the image attached below. Then, the triangle satisfies the following equation:
(1)
The value of is 10º.
