Answer:
But on what question??
Step-by-step explanation:
Answer:
Step-by-step explanation:
The number of sandwiches sold: 73
The cost to make one sandwich: S
The profit the band earns from one sandwich: 0.2S
The amount of money that the band recieves for selling one sandwich:
S + 0.2S
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
____________________________________
Total Numbers
15 = 3 + 19 + 8 + 32 + x
______________
5
Cross Multiply
___________
3 + 19 + 8 + 32 + = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
For 14, the answer is >. You inversed it. You are right about question 15.
Answer:
3x-20=-6.6 degrees, 7x+10=1.4 degrees
Step-by-step explanation:
You solve each equate separately. So take the equation (3x-20) and solve for x first in that one. so you divide 3 by -20 to get -6.66 degrees for your first angle. Then you solve the other equation. (7x+10) divide 7 by 10 to get the angle measurement. Which would be 1.4 degrees.
