Answer: the number of hotdogs that were sold is 35
the number of orders of fries is 52
Step-by-step explanation:
Let x represent the number of hotdogs that were sold.
Let y represent the number of orders of fries.
You sold a total of 87 hotdogs and orders of fried combined. This means that
x + y = 87
Each hot dog costs 1.50 and each order of fries costs 0.50. At the end of the night you made a whopping $78.50! This means that
1.5x + 0.5y = 78.5 - - - - - - - - - - -1
Substituting x = 87 - y into equation 1, it becomes
1.5(87 - y) + 0.5y = 78.5
130.5 - 1.5y + 0.5y = 78.5
- 1.5y + 0.5y = 78.5 - 130.5
- y = - 52
y = 52
Substituting y = 52 into x = 87 - y, it becomes
x = 87 - 52
x = 35
3(1+x) - 5 =3x-2
3+3x-5=3x-2
3x-2
Hope this helps!
(-2 + 3i + (5 - 2i)
= -2 + 5 + 3i - 2i
= 3 + i Answer
the formula for point slope form is y-y1=m(x-x1)
m is your slope
y1 is your y in the ordered pair
x1 is the x in your ordered pair
example: (5,7) slope is 3
y-7=3(x-5)
Answer:
y= v/6
