At The Movies, A Couple Bought 2 Medium Drinks And A Large Popcorn For $13.85. At The Same Theater, A

Answers

Answer 1

Answer:

cost of one medium drink = $3.80

cost of one large popcorn = $6.25

Step-by-step explanation:

Let D = cost of one medium drink

Let P = cost of one large popcorn

If a couple bought 2 medium drinks and a large popcorn for $13.85:

⇒ 2D + P = 13.85

If a family bought 3 medium drinks and 2 large popcorn for a total of $23.90:

⇒ 3D + 2P = 23.90

Rewrite 2D + P = 13.85 to make P the subject:

⇒ P = 13.85 - 2D

Substitute into 3D + 2P = 23.90 and solve for D:

⇒ 3D + 2(13.85 - 2D) = 23.90

⇒ 3D + 27.7 - 4D = 23.90

⇒ D = 3.8

Substitute found value of D into P = 13.85 - 2D to find P:

⇒ P = 13.85 - (2 x 3.8) = 6.25

Therefore,

cost of one medium drink = $3.80

cost of one large popcorn = $6.25

Answers

Answer:

s = 6

Step-by-step explanation:

[tex]\frac{21}{14} =\frac{s}{4}[/tex]

1- cross multiply

21 x 4

= 84

-------------

14 x s

= 14s

SO..

14s = 84

2- to find 's' divide both sides by 14

[tex]\frac{14s}{14} = \frac{84}{14}[/tex]

s = 6

s=6
21/14 simplified is 3/2 after you divide by 7. now you need to find a fraction that is equal to 3/2 with a denominator of 4. to do this you multiply both numbers in the fraction 3/2 by 2. you get 6/4. s=6.

Five students came for after-school tutoring. Lin’s teacher assigned each of them the same number of problems to complete. Then he assigned each student 2 more problems. 30 problems were assigned in all.

Answers

Answer:

Equation: 5x + 10 = 30

Simplified Equation: 5x = 20

Number of problems assigned per person (at the start): 4

Total number of problems assigned per person: 6

Step-by-step explanation:

Hello!
We know that there were 5 students at the after-school tutoring and that the same number of problems were assigned to each person.

Let x = # of problems assigned to each student.

Since there were 5 students, x is multiplied by 5 so we can represent that as 5x

Next, 2 problems were assigned to each of the 5 students, so that can be represented as 5*2 or 10

If we add both values, they should equal to 30:

5x + 10 = 30

Simplified version: 5x = 20

Value of x : 4

If I right understood, there are needed to translate it as a percentage. It’s not hard. For example: If 500 is 100%, then the 50% is 1/2 from 100%, I.e. 50% from 500 is will be 250, because, it’s 1/2 from all sum.

When calculating percentages, it is most convenient to first calculate 1 percent of the number. From 500 it will be 5%, because 100% of 100 is 1, and 500 divided by 100 will be 5. Just solve a little problem with percentages and you will solve it without thinking.
