Answer:
d
Step-by-step explanation:
Given:
A figure of a circle.
To find:
The value of x.
Solution:
Central angle theorem: According to this theorem, the central angle on an arc is twice of the subtended angle on that arc.
Using the central angle theorem, we get
Therefore, the value of x is 70 degrees.
The answer to this question would be: C.5x = 5
In this question, you got two equation which was:<span>1st: 2x + y = 3
2nd: x - 2y = -1</span>
You are asked to multiply one of the equation and add it. If you multiply the first equation, the number of y would be same so the y variable will be removed. If you multiply the second equation, the number of x would be same so the x variable will be removed.
In the answer, all variable that used is x, so the one you need to multiply should be the first equation(removing y with result with x)
<span>4x + 2y = 6
x - 2y = -1
__________+
5x +0y = 5

Change the sales tax to a decimal which would be 0.085 and multiply that by 505.95$ to get 43$ which is the sales tax, then add that to the original amount 505.95$ to get the total cost after tax which is 548.96$ rounded to the nearest cent.
