The math club sells candy bars and drinks during football games.
Vinvika [58]

Answer:

The price of candy bar is 75 cents

Step-by-step explanation:

Let c be the price of candy bar and d be the price of drinks

Then according to given statements

60c+110d = 265\ \ \ \ Eqn\ 1\\120c+90d = 270\ \ \ \ Eqn\ 2

Multiplying equation 1 by 2

120c+220d = 530\ \ \ \ Eqn\ 3

Subtracting equation 2 from equation 3

120c+220d - (120c+90d) = 530 - 270\\120c+220d-120-90d = 260\\130d=260

Dividing both sides by 130

\frac{130d}{130} = \frac{260}{130}\\d = 2

Putting d=2 in equation 1

60c+110(2) = 265\\60c + 220 = 265\\60c+220-220 = 265-220\\60c=45\\c = \frac{45}{60}\\c = 0.75

Price of candy bar is $0.75 or 75 cents

Hence,

The price of candy bar is 75 cents

Q bisects PR If PR = 28, andPQ = 2x + 5, what is the value of x? Show your work​
dlinn [17]

Answer:

The value of x is 11.5

Step-by-step explanation:

Here, we want to find the value of x

Since Q bisects PR, it means it divides PR into ii equal angles

Thus PR = PQ

28 = 2x + 5

2x = 28-5

2x = 23

x = 23/2

x = 11.5
