Answer:

Step-by-step explanation:
bisects
and
.


Solve for m.
Subtract 3m from both sides.

Divide both sides by 3.

Calculate
.


Put m = 7.



Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
−4y+4y+2=2
Step 1: Simplify both sides of the equation.
−4y+4y+2=2
(−4y+4y)+(2)=2(Combine Like Terms)
2=2
2=2
Step 2: Subtract 2 from both sides.
2−2=2−2
0=0
Answer:
All real numbers are solutions.
Answer:
0
Step-by-step explanation:
Well average means mean so we have to find the mean of the numbers in the data set. Our numbers are -12,12,-4, and finally 4. When we add all of them up we get 0 and we have to divide 0 by the 4 thermoters and your answer is 0. if this is confusing just leave a comment and ill try to explain better
Answer:
Error
Step-by-step explanation:
(-94)/5+22/22 Given
-18.8+1 PEMDAS (do -94/5 and 22/2)
-17.8 Add the numbers
After you add the numbers, you take the square root. you will get the answer "Error" because you cannot take the square root of a negative number
Answer:
c) 82
Step-by-step explanation:
<ABE and <BEC are supplementary because they form a line.
<ABE + <BEC = 180
116+ x = 180
Subtract 116 from each side.
116-116+x = 180 -116
x = 64
The angles in triangle ECB add to 180 because it is a triangle
<BEC + <ECB + <CBE = 180
x + 34+y = 180
64 + 34+ y = 180
98 + y = 180
Subtract 98 from each side.
98-98+y = 180-98
y = 82
