Step-by-step explanation:

The number of hardcover books will be 3,4, and 8.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tim is sorting his book collection into groups. He places each group onto bookshelves that can each hold a maximum of 25 pounds. His collection includes hardcover books that weigh 3 pounds each and softcover books that weigh 2 pounds each.

Total weight = 25 pounds

The number of hardcover books which weigh less than 25 pounds is,

3 x 3 pounds = 9 pounds

4 x 3 pounds = 12 pounds

8 x 3 pounds =- 24 pounds

Therefore, the number of hardcover books will be 3,4, and 8.

Answer:

p + 2c = 3.25 Start with these two equations

3p + 4c = 7.25

p = -2c + 3.25 Solve for one variable

3(-2c +3.25) + 4c = 7.25 Substitute

-6c + 9.75 + 4c = 7.25

-2c = -2

c = 1

p + 2(1) = 3.25 Substitute

p + 2 = 3.25

p = 1.25

Answer:

B

Step-by-step explanation:

we are given a equation of a line

we want to figure out the equation of the perpendicular line passes through the (6,5) points

in order to do so

recall that,

[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{m} [/tex]

we got from our given equation that m=2

because equation of a line is y=mx+b

thus

[tex] \displaystyle m_{ \text{perpendicular}} = - \frac{1}{2} [/tex]

remember that, when we want to figure out perpendicular line or parallel line we should the formula given by

[tex] \displaystyle y - y_{1} = m(x - x_{1})[/tex]

since we got our perpendicular m is -½, [tex]x_1=6[/tex] and [tex]y_1=5[/tex], substitute

[tex] \displaystyle y - 5 = - \frac{1}{2} (x - 6)[/tex]

to get the perpendicular equation you should simplify the above equation to y=mx+b form

distribute -½:

[tex] \displaystyle y - 5 = - \frac{1}{2} x + 3[/tex]

add 5 to both sides:

[tex] \displaystyle y = - \frac{1}{2} x + 8[/tex]

hence,

our answer choice is B

Answer:

the length of the  longer piece of cable is 24 ft

Step-by-step explanation:

shor piece = s

Long piesce = s+9

s + s+9= 39

2s = 30

s = 15

short = 15

15 +9 = 24

long = 24

15+24 = 39

Answer:

24 feets

Step-by-step explanation:

let the shorter cable be x feets

so the longer cable will be 9 plus the shorter cable which is (9 + x) feets

[tex]x \: = \: \frac{30}{2} \\ x = 15feets[/tex]

Answer:

Step-by-step explanation:

Now the formula to find the volume of a pyramid is  [tex]V=\frac{lwh}{3}[/tex]

We know the length, width and height so let´s get started!

First let´s multiply to find the base. To do so, we will do length × width.

18 × 18 = 324

Now multiply by the height

324 × 12 = 3,888

After you multiply all length, width and height, we need to divide by three.

3,888 ÷ 3 = 1,296

Before we finish, we need to do the last two steps

First we need to add the measurement unit which is centimetres or cm.

We also need to add ³ since it is volume

1,296 cm³ is our final answer
