Answer:

3 9/10

Step-by-step explanation:

The decimal part is 0.9. To convert that, keep the 9. Since the 9 is in the tenths place, it is 9/10.

Add them together: 3+9/10= 3 9/10

Final answer 3 9/10

Hope this helps

You are running a concession stand at a basketball game. You are selling hot dogs and sodas. Each hot dog costs $1.50 and each s
DochEvi [55]

Answer:

<u>x= 35 hot dogs</u>

<u>y= 52 soda</u>

Step-by-step explanation:

x= hot dogs

y= soda

Total sold

1 x + 1 y = 87 .............1

2 x 0.50 y = 78.50 .............2

Eliminate y

multiply (1)by -0.50

Multiply (2) by 1.00

-0.50 x -0.50 y = -43.50

2 x + 0.50 y = 78.50

Add the two equations

1 x = 35.00

/ 1

x = 35.00

plug value of x in (1)

1 x + 1 y = 87

35 + y = 87

y = 87 -35

y = 52

y = 52.00

x= 35 hot dogs

y= 52 soda
