at a lunch stand, each hamburger has 50 more calories than each order of fries. if 2 hamburgers and 3 orders of fries have a total of 1700 calories, how many calories does a hamburger have?

Answers

Answer 1
Answer:

The correct answer is 370. A system of equations can be used, where h represents the number of calories in a hamburger and f represents the number of calories in an order of fries. The equation  2 h plus 3 f equals 1,700 represents the fact that 2 hamburgers and 3 orders of fries contain a total of 1700 calories, and the equation  h equals f plus 50 represents the fact that one hamburger contains 50 more calories than an order of fries. Substituting  f plus 50 for h in  2 h plus 3 f equals 1,700 gives  2, parenthesis, f plus 50, close parenthesis, plus 3 f, equals 1,700. This equation can be solved as follows:

 

 2 f plus 100 plus 3 f equals 1,700

 5 f plus 100 equals 1,700

 5 f equals 1,600

 f equals 320



The number of calories in an order of fries is 320, so the number of calories in a hamburger is 50 more than 320, or 370.

At the gas station, each liter of gas costs $ 3 $3dollar sign, 3, but there's a promotion that for every beverage you purchase you save $ 0.20 $0.20dollar sign, 0, point, 20 on gas.

Answers

The complete question is:

At the gas station, each liter of gas costs $3dollar but there's a promotion that for every beverage you purchase you save $0.20 dollar on gas. Is your total savings on gas proportional to the number of beverages you purchase?

Answer:

  • Yes, your total savings on gas is proportional to the number of beverages you purchase.

Explanation:

What is a proportional relationship?

A proportional relationship, also known as direct relation, between two variables exists when the ratio between every pair of data is constant.

In this case the variables are:

  • number of beverage purchased
  • savings

Thus, as per every beverage purchase you save $ 0.20 the ratio of total savings to the number of beverage purchases is:

  • savings / beverages purchase = $ 0.20 / beverage

That means that you can determine the savings by multipliying the number of beverages times $ 0.20.

For proportional relationships it is easy to build a table that shows the behavior of the variables. This shows you that:

Number of beverages   savings    ratio

         1                              $ 0.20      $0.20 / 1 beverage = 0.20

         2                             $ 0.40      $0.40 / 2 beverages = 0.20

         3                             $ 0.60       $0.60 / 3 beverages = 0.20

         4                             $ 0.80       $0.80 / 4 beverages = 0.20

Which inequality models this situation? The time between two trains must be greater than 37 minutes.

A.
t < 37

B.
37 > t

C.
37 – t = 0

D.
t > 37

Answers

The inequality t > 37 models the equation correctly, in which it is stated that the time between two trains must be more than 37 minutes. Here, t represents the time between the two trains.

Answer:

The answer would be A

Step-by-step explanation:

you are planting a rectangle garden. it is 5 feet longer than 3 times its width. the area of the garden is 250 feet. find the dimensions

Answers

l=3w+5
2(3w+5)+2w=250 (both w and l have to be multiplied by two because there are two sides)
This can be simplified to: 6w+10+2w=250
Now subtract 10 from both sides and add the two w's together.
This makes: 8w=260
Divide both by 8: 32.5-w=32.5
32.5 times 2=65
250-65=185, divided by 2=92.5

Length=92.5
Width=32.5
