(10x5)+(30+20)x10-100-1

First solve everything in parenthesis.

50+50x10-100-1

Then, because of PEMDAS (Parenthesis, exponent, multiplication/division, addition/subtraction) you need to then do 50x10.

50+500-100-1

Then, because addition and subtraction can be switched around you do 50+500 first.

550-100-1

Then you do 550-100.

450-1

Then you subtract 450-1 and get your answer.

450-1=449

Hope this helps and have a nice day!!!

Answer:

899 would be your answer

Step-by-step explanation:

10x5=50

50+30=80

80+20=100

100x10=1000

1000-100=900

900-1=899

Hope this helps you!

Theo bought 2 hot dogs and two drinks for $4.00. At the same concession stand, Vicky bought 3 hot dogs and a drink for $4.50. Wr
Sedbober [7]

Answer:

The hot dog are $2.63

Step-by-step explanation:

Hot Dogs = H

Drinks = D

2H + 2D = 4

Divide both sides by 2

H + D = 2

Subtract D from either side

H = 2 -D

3H + D = 4.50

Plug in 2 - D for H

3(2- D ) + D = 4.50

6 - 3D + D = 4.50

6 - 4D = 4.50

Add 6 to either side

-4D = 10.50

Divide either side by -4

D = -2 . 625
