Grace’s because she followed the order of operations. Addition and subtraction first, then multiply and divide.
Answer:
x = 8
Step-by-step explanation:
In order for the triangles to be similar, corresponding side must be in proportion.
So, FE/ZY = FD/ZX
6/12 = (2x - 5)/22
6(22) = 12(2x - 5)
132 = 24x - 60
24x = 192
x = 8
The question provides one endpoint and then the midpoint. The midpoint on the coordinate grid is (0, -7) and one endpoint is (-2,-6).
The formula for calculting the midpoint is given as follows;
Therefore, the coordinates of B is calculated as (2, 20)
Both A and B would be correct to use. You can use an example of your own to check it yourself. For example I did 10 emails all together and kept trying with the equations.
