Answer = -4
Step-by-Step Explanation:
Given: x = 2, y = -9
Therefore, substituting the values
= 7x + 2y
= 7(2) + 2(-9)
= 14 + -18
= 14 - 18
= -4

Answer: 18
Step-by-step explanation:
By the angle bisector theorem, 
Answer:
7 1/24
Step-by-step explanation:
First, you have to get the fractions to have the same denominator. So, you take 2/3 and 3/8 and find the smallest number by multiplying for the denominator. That number is 24 because 3 times 8 is 24 and 8 times 3 is 24.
Then, you multiply both the denominator and the numerator by the number that you got for the fractions. 2 * 8 = 16 3 * 8 = 24. 3 * 3 = 9 8 * 3 = 24. So, that gives you 16/24 and 9/24. Now since they have the same denominator you can add them.
This gives you 25/24 which equals 1 1/24.
Next, you can add the whole numbers. That is 6.
Lastly, take your fraction answer and your whole number answer and you get 7 1/24.
I hope this helps! =)
Answer
z= 14
Step-by-step explanation:
4( 2z-3) -5(z-6) =3 *20
8z-12-5z+30=60
3z+18=60
3z=60-18
3z=42
z= 14
