Answer:
132°
Step-by-step explanation:
Angle JKH and IHK are alternate interior angles, and thus congruent.
Since JKH is 132 degrees, so is IHK
Answer:
1. 12
2. 5
3. 24
4.9
Step-by-step explanation:
1 ticket is $3
Answer:

Step-by-step explanation:
We want to solve for x in 
You need to group and combine like terms and write in standard form:


By comparing to
, we a=1,b=-2 and c=-46
The solution can be obtained using the quadratic formula.

We substitute the coefficients to get:





The last choice is correct
Step-by-step explanation:
it is unbiased because the people are chosen at random
Step-by-step explanation:
4 + n + 7m
constants are just the numbers with no variables (letters)
so the constant is 4
coefficients are numbers multiplied by variables (letters)
so the coefficients are : 7 and 1
the error sarah made is forgetting the coefficient of n......because even if it is not written, n is the same as 1n....so basically, there is a coefficient for EVERY variable, even if its not written.
