Step-by-step explanation:
Unit rate would be price per 1 pizza. Divide 70 by 9
To find unit cost.
70/9= $7.78 each
To use the substitution method we need to convert one equation in terms of a certain variable and substitute this equation to the other equation. For this case we are asked to substitute the first equation to x in the second equation. Therefore, the equation to substitute is:
<span>-x - 2y = -4
</span>x = 4 - 2y
Answer:
-16
Step-by-step explanation:
The average of –25, –70, 15, –31, –25, and 40 is -16
To determine the average of the numbers given, we shall find their sum then divide this sum by the number of values;
The sum of the numbers is;
-25-70+15-31-25+40 = -96
We have a total of 6 values, thus the average becomes;
(-96)/6 = -16
