Answer:
6.30$
Step-by-step explanation:
If you add 7.80$ and 7.80$ that come to 4 hot dogs,
The rest of the money is how much one soda cost ( 2.40$ ),
Dividing that 7.80$ by 2, To only have one hot dog, would put you at
3.90$ fro one hot dog, then all you have to do is add them together, to get the total of 6.30
7.80 | 17.00 | 7.80/2 | 2.40
+ 7.80 | - 15.60 | 3.90 | + 3.90
15.60 | 2.40 | | 6.30

Answer:
E) 1/2
Step-by-step explanation:
This is no ordinary problem. It actually requires you to solve two different problems in order to figure out the correct answer.
First, we must figure out what the hypotenuse of the triangle is. We have the two small sides (5 and 12), but don't have the larger side. To find this, we must use the Pythagorean theorem: 
Let's plug in our a and b values
Simplify
Square both sides
But sadly, we aren't done yet. Now we know the length of the whole hypotenuse side. Time to figure out what X is by a simple equation.
Simplify
Divide by 26
Answer is 1/2
Answer:
6 hours
Step-by-step explanation:
Let
x----> the number of hours worked at the donut shop
y----> the number of hours worked at the school bookstore
we know that
x+y=20
x=20-y -----> equation A
10.25x+8.75y=196 -----> equation B
Substitute equation A in equation B and solve for y
10.25(20-y)+8.75y=196
205-10.25y+8.75y=196
10.25y-8.75y=205-196
1.5y=9
y=6 hours at the school bookstore
