The Puck family of five are going to the movie theatre. The family consists of two adults and three children. The admission cost

s are $10.50 per adult and $6.50 per child.
Mr. Puck will buy each person a large drink and one tub of popcorn for everyone to share. He does not know the cost of food/drinks until he arrives at the theatre.

Write an expression that represents the admission price, popcorn, and drinks, for the whole family. Let d represent the cost for a large drink and let p represent the cost of the popcorn. The expression must include parentheses. Then simplify the expression by using the Distributive Property and combining like terms.




If a large tub of popcorn is $7.50 and large drinks are $6.00 each, how much did Mr. Puck spend at the movies?

Given the recursive formula:<br> a1=3<br> An=2(an-1+1)<br> Find a2 a3 a4
fenix001 [56]

Answer:

a_2 = 8

a_3 = 18

a_4 = 38

Step-by-step explanation:

We are given the following recursive formula:

a_n = 2(a_{n-1}+1)

And consider a_1 = 3

a2

a_2 = 2(a_1 + 1) = 2(3 + 1) = 8

a3

a_3 = 2(a_2 + 1) = 2(8 + 1) = 18

a4

a_4 = 2(a_3 + 1) = 2(18 + 1) = 38

All about simulitious equations​
Korolek [52]

Answer:

On occasions you will come across two or more unknown quantities, and two or more equations

relating them. These are called simultaneous equations and when asked to solve them you

must find values of the unknowns which satisfy all the given equations at the same time.

Step-by-step explanation:

1. The solution of a pair of simultaneous equations

The solution of the pair of simultaneous equations

3x + 2y = 36, and 5x + 4y = 64

is x = 8 and y = 6. This is easily verified by substituting these values into the left-hand sides

to obtain the values on the right. So x = 8, y = 6 satisfy the simultaneous equations.

2. Solving a pair of simultaneous equations

There are many ways of solving simultaneous equations. Perhaps the simplest way is elimination. This is a process which involves removing or eliminating one of the unknowns to leave a

single equation which involves the other unknown. The method is best illustrated by example.

Example

Solve the simultaneous equations 3x + 2y = 36 (1)

5x + 4y = 64 (2) .

Solution

Notice that if we multiply both sides of the first equation by 2 we obtain an equivalent equation

6x + 4y = 72 (3)

Now, if equation (2) is subtracted from equation (3) the terms involving y will be eliminated:

6x + 4y = 72 − (3)

5x + 4y = 64 (2)

x + 0y = 8

Cooper's USB drive is 1··2full with 5 video files. Each video file is the same size. What fraction of the USB drive does 1 video
lidiya [134]

Answer:

the fraction of the USB drive when one video file use is 10%

Step-by-step explanation:

The computation of the fraction of the USB drive when one video file use is given below:

= USB drive × number of video file ÷ number of video file

= half × 1 ÷ 5

= 0.5 × 1 ÷ 5

= 0.10

= 10%

Hence, the fraction of the USB drive when one video file use is 10%
