scZoUnD [109]3 years ago

Answer:

y=50 and x=-173/2

Step-by-step explanation:

52-2y=-48

∴-2y=-100

y=50

and 2x+3y=-23

y=50→(1)

2x+3y=-23→(2)

Putting y=50 in equation (2), we get

⇒2x+3y=-23

⇒2x+3(50)=-23

⇒2x+150=-23

⇒2x=-23-150

⇒2x=-173

⇒x=-173/2

∴y=50 and x=-173/2

Heeeeeeeeeeeeeellllllllppp
USPshnik [31]

Answer:

Step-by-step explanation:

let price of  one pretzel=x

price of one soda=y

3x+4y=11.25   ...(1)

5x+2y=8.25    ...(2)

multiply by 2

10x+4y=16.50   ...(3)

(3)-(1) gives

7x=5.25

x=0.75

from (1)

3(0.75)+4y=11.25

2.25+4y=11.25

4y=11.25-2.25

4y=9

y=9/4=2.25

cost of one pretzel=$0.75

cost of one soda=$2.25

The volume of a cylinder is 176 cm and its height is 11 cm,
Mekhanik [1.2K]

Answer:

4cm

Step-by-step explanation:

The volume of the cylinder is the product of the area of the base and the height. In mathematical equation, this can be written as,

                                     V = πr²h

where V is volume, r is the radius, and h is the height.

Substituting the known values from the given,

                                 176π cm³ = πr²(11 cm)
