Answer:

The price of hot dog is $2.5 and that of a pretzel is $1.25.

Step-by-step explanation:

Let the cost of hotdogs be x and that of pretzels be x.

So,

4x+3y = 13.75 ...(1)

and

2x+5y = 11.25 ...(2)

Multiply equation (2) by 2.

4x+10y = 22.5 ...(3)

Subtract equation (1) from (3).

4x+10y-(4x+3y) = 22.5-13.75

4x+10y-4x-3y = 8.75

7y = 8.75

y = 1.25

Put the value of y in equation (1).

4x+3(1.25) = 13.75

4x+3.75 = 13.75

4x = 13.75-3.75

4x = 10

x = 2.5

So, the price of hot dog is $2.5 and that of a pretzel is $1.25.

BARSIC [14]

First, we need to isolate the variable x.

To isolate x, we simply need to multiply both sides by 9, which would result in x = 9

Weight: How many grams does a 5 lb 15 oz roast weigh?The roast weighsgrams.
natulia [17]

Since 1kg = 2.20 lb,

\frac{1\operatorname{kg}}{2.20\text{ lb}}

Since 1kg = 1000g

\frac{1000\text{ g}}{1\operatorname{kg}}

So for covering pounds to gram by the following factor

\frac{1\operatorname{kg}}{2.20\text{ lb}}\frac{1000\text{ g}}{1\operatorname{kg}}

Since 1oz = 28.3g

\frac{28.3\text{ g}}{1\text{ oz}}

Now

5\text{ lb}\frac{1000\text{ g}}{2.20\text{ lb}}+15\text{ oz}\frac{28.3g}{1\text{ oz}}

The weight in grams would be

2697.22 gr
