Answer: 11
============================================
Explanation:
Point C is the circumcenter of triangle PQR. This means that we can draw a circle centered at C that goes through points P, Q and R at the same time. This circle has a special name: circumcircle.
The segments PC, RC and QC are all radii, so they are the same length. Pick two of the given expressions and set them equal to one another. Then solve for x
I'm going to pick the expressions for PC and RC
PC = RC
3x+7 = 5x-15
5x-3x = 7+15
2x = 22
x = 22/2
x = 11
Answer:
X = 0
Y = -3
Step-by-step explanation:
In this situation you would choose elimination.
-6x+y=-3
7x-y=3
---------------
x = 0
plug back in to find y
(-6)(0) + y = -3
0 + y = -3
y = -3
plug in to other equation for double check
7(0) - (-3) = 3
0 + 3 = 3
3 = 3
Hope this helps
Answer:
The error is the exponent in the answer should be 11.
Step-by-step explanation:
When you move the decimal place one spot as they do in the final step to move it from a base 10 to a base 1, we have to add a exponent on. Therefore, it should go from 10 to 11.
Answer:
10
Step-by-step explanation:
130+40+x =180
x=10
