Answer:
C
Step-by-step explanation:
i took the test
Let x be the number.
Then;
6x-18=-42 (solve for x now)
6x=-42+18
6x=-24
x=-4
Therefore, this number would be -4.
Hope I helped :)
Answer:
Step-by-step explanation:
To solve, we need to take square root of both sides first:
Now we use the property of radical shown below to simplify square root of 28:
Property: 
Now, we have:
Now we take 4 to the other side and isolate x:
first answer choice is right.
Answer:
um well if C would be the X then
Step-by-step explanation: 2 times 2 is four now you have to figure out which number minus 4 is 5 which would be nine then you go back to the 3x part and the only way to get nine from a 4-3 is it would have to be a negetive so then you see that 2 plus seven is 9 or 2- (-7) is 9 so you find three times -7 =-2.33333333
Angle C is 40degree
Then Angle B is supposed to be 180-90-40 which will be 50 degree
