10.5x + 3y = 811.5
x + y = 97
y = 97 - x
3y = 291 - 3x
7.5x + 291 = 811.5
7.5x = 811.5 - 291
x = 520.5 / 7.5
x = 69.4
69 were sold at the original price
Answer: 300ft
Step-by-step explanation:
The answer is -3.
To find this, we simply have to solve the equation and leave only the blank and the parenthesis that it is with on the right side. Then we can divide by the parenthesis. The work for this is done for you below.
____(x - 3) + 2x = -(x - 5) + 4 ----> Distribute the -1 to the parenthesis.
____(x + 3) + 2x = -x + 5 + 4 ----> Simplify
____(x + 3) + 2x = -x + 9 ----> Subtract 2x from both sides
____(x + 3) = -3x + 9 ------> Divide both sides by x + 3
____ = -3.
Answer:
The value of y s 2.5
Step-by-step explanation:
Vertical angles are always equal to one another. In this case, we can find the angles by setting the two values equal and solving algebraically.
2y + 5 = 4y
5 = 2y
2.5 = y
