6p + 4 / 7 + 5p - 6 / 2 - 3p / 4 when p = 4

vesna_86 [32]

Step-by-step explanation:

Given p = 4,

substitute p= 4 into the expression

6p+4/7+5p-6/2-3p/4

$6(4) + \frac{4}{7} + 5(4) - \frac{6}{2} - \frac{3(4)}{4} \\ = 24 + \frac{4}{7} + 20 - 3 - 3 \\ = 44 + \frac{4}{7} - 3 - 3 \\ = 38 + \frac{4}{7} \\ = 38 \frac{4}{7}$

Jesse is building a spice rack. He cuts three lengths of wood from a 90-centimeter board. The first length is 23.5 centimeters.

romanna [79]

Since, Jesse is building a spice rack.

The total length of wood = 90 centimeters

He cuts the board into three parts.

The length of the first part = 23.5 cm

So, remaining length of the board = $90 - 23.5$ = 66.5 cm

Now, he cuts the second part.

The length of the second part = 33.3 cm

So, now remaining part of the board = $66.5 -33.3$ = 33.2 cm

Now, he cuts the third part of the board.

The length of the third part = 19.45 cm

Now, the remaining part of the board = $33.2-19.45$ = 13.75 cm

So, the length of the original board after cutting the three parts = 13.75 cm

So, Option A is the correct answer.

At the movie theater, child admission is $5.50 and adult admission is $9.10 . On Saturday, four times as many adult tickets as c

TEA [102]

Answer:

Number of child tickets sold that day = 25 tickets

Explanation:

Assume that the number of the adult ticket is x and that the number of the child ticket is y.

We are given that:

1- four times as many adult tickets as child tickets were sold. This means that:

adult tickets = 4 * child tickets

x = 4y ....................> equation I

2- Child ticket costs $5.5, adult ticket costs $9.1 and total sales was $1047.5.

This means that:

x(9.1) + y(5.5) = 1047.5

9.1x + 5.5y = 1047.5 ..................> equation II

Substitute with equation II in equation I and solve for y as follows:

9.1x + 5.5y = 1047.5

9.1(4y) + 5.5y = 1047.5

36.4y + 5.5y = 1047.5

41.9y = 1047.5

y = 25

Based on the above calculations:

number of child tickets = y = 25 tickets

number of adult tickets = x = 4y = 4(25) = 100 tickets

Hope this helps :)

ycow [4]

Answer:

1,032,564 tickets

Step-by-step explanation:

Find how many tickets they sell in total by multiplying the capacity of the stadium by the number of games in the season:

86,047(12)

= 1,032,564

So, if every game sells out, 1,032,564 tickets will be sold.
