Answer:
Step-by-step explanation:
ABC is the sum of the angles CBD and ABD. So:
Substitute them for their equations:
Solve for x. Combine like terms on the right:
Add 11x to both sides:
Subtract 241 from both sides:
Divide both sides by 4:
The value of x is 9.
And we're done!
Answer & Step-by-step explanation:
In order to solve this problem, it's important that we look at the tiles and the the signs that are in front of them. The top row of tiles represents our first expression and the bottom row of tiles represents our second equation.
The two large tiles are positive so they are going to be positive in our equation.
(x² ) - (-x² )
The four blue rectangle tiles are also positive, so they are going to be positive in our equation. The two red rectangle tiles are negative, so they are going to be negative in out equation.
(x² + 4x) - (-x² + 2x)
The two red square tiles are negative, so they are going to be negative in our equation. The four blue square tiles are positive, so they are going to be positive in our equation.
(x² + 4x - 2) - (-x² + 2x - 4)
So, your answer is going to be letter choice C.
We have:
y = 4x - 5
Lets add 5 in each member:
y + 5 = 4x - 5 + 5
y + 5 = 4x
Divide the entire equation by 4:
Sales tax rate = 43.70-40
=3.7 the answer is 3.7$
