Answer:
17
Step-by-step explanation:
since it is in the middle you can just divide by 3 since one will be greater and one will be less so 51/3=17
Answer:
c
Step-by-step explanation:
9x-4 (x-3)+72
9x-4x+12+72
5x+84
5x/5 + 84/5
x=17
Answer:
Let x = # of commercials
y = # of movies
<u>System of Equations:</u>
x + y = 90
40x + 110y = 500
Step-by-step explanation:
We have to set our variables before we start solving. After setting the variables, we can set up the equations. If x = # of commercials and y = # of movies, then we can assume x + y = 90, as there have been a total of 90 commercials and movies played altogether. Then, we know that their worth is $500, so the price of all the commercials played and the price of all the movies played (which is 40x + 110y) sum to $500.
A = 1/2(15+7+15+7)(13)
A= 1/2(44)(13)
A = 286
answer
286
Answer:

Step-by-step explanation:
Factor each half of the expression separately:

Since both 4k² and 7 are being multiplied by (7k-6), we can combine them to get:
