<span>Each hot dog costs $ 1.50 and each soda costs $ .50. You made a total of $ 78.50. You sold a total of 87 hot dogs and sodas combined. You must report the number of hot dogs and soda's sold. How many hot dogs and soda's were sold?
Quantity Equation: h + s = 87
Value Equation:: 1.5h+0.5s=78.50
Multiply thru the Quantity Equation by 15
Multiply thru the Value Equation by 10.
15h + 15s = 15*87
15h + 5s = 785</span>Subtract and solve for "s":<span>10s = 520
</span>s = 52 (# of soda's sold)
<span>
Solve for h:
h + s = 87
h + 52 = 87
h = 35 (# of hot dog's sold)</span>
Answer: -9
Step- by - step:
x+2>-7
x>-7-2
x>-9
= -9
what is the other number fore the first part?
Take 3 out of both of them
3(5x+2)
vertical angles are equal
7x+28 = 5x+22
subtract 5x from each side
2x +28 =22
subtract28 from each side
2x =-6
x = -3
angle a
7x+28
7(-3) +28
-21+28
7
Angle A =7
