= {[2 * 8 + 2 * (-3)] + 30 - 5} / 5 =
= [(16 - 6) + 25] / 5 =
= (10 + 25) / 5 =
= 35 / 5 =
= 7

Brackets make it look complex but it's not that bad at all :)

Answer:

The answer is 7.

Step-by-step explanation:

First we will solve this as per pemdas.

{[(8-3)\times2]+[(5\times6)-5]}

= {[5\times2]+[(5\times6)-5]}

=> {[10]+[(30)-5]}

=>  {[10]+[25]}

= 35

Now 35 divided by 5 = 7

\frac{35}{5}=7

Therefore, the answer is 7.

Line M passes through the points (1,2) and (3,5) , find the X- and Y- intercepts
Alexeev081 [22]
Ok. So first, we calculate the slope!

m=(y2-y1)÷(x2-x1)= (5-2)÷(3-1)=3/2.

Now that we have the slope, we can start to write an equation for the line by plugging in the given points. b is the y-intercept.

y=mx+b.
2=(3/2)1+b
b=2-(3/2)=2-1.5=.5 or 1/2

so the y-int is (0,.5 or 1/2) .

Next, we have to find the x-int.

to do that, we just plug in 0 for the y.

0=1.5x+.5
x=-.5/1.5= (1/3)

so the x-intercept is
(1/3 or .33,0).

There are three times as many fiction books as non-fiction books in a library. 122 fiction books and 24 non-fiction books are lo
Alexxx [7]

Answer:

176 books

Step-by-step explanation:

Let's call the number of fiction books 'F', and the number of non-fiction books 'N'. Then, we can write the following system of equations:

eq1:

F = 3N

eq2:

2*(F - 122) = (N - 24)

2F - 244 = N - 24

2F = N + 220

Using the 'F' value from the first equation, we have:

6N = N + 220

5N = 220

N = 44\ books

F = 3N = 132\ books

The total number of books is:

F + N = 132 + 44 = 176\ books

Can somone pls help me with this I have a C- in math and I really need help also a like show work on each one plsss
Lady bird [3.3K]

Answer:

1. \frac{3}{8}

2. \frac{1}{4}

3a. -\frac{1}{4}

3b. 3

3c. -\frac{4}{5}

4. m = \frac{y_1 - y_2}{x_1-x_2}\\

Step-by-step explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

m = \frac{y_1 - y_2}{x_1-x_2}

m = \frac{3-2}{-2-2}

m = \frac{1}{-4}

m = -\frac{1}{4}

3b.

m = \frac{y_1 - y_2}{x_1-x_2}\\

m = \frac{-1 - 2}{-1-0}

m = \frac{-3}{-1}

m = 3

3c.

m = \frac{y_1 - y_2}{x_1-x_2}\\

m = \frac{1 - (-3)}{-1-4}\\

m = \frac{4}{-5}\\

m = -\frac{4}{5}

4.

m = \frac{y_1 - y_2}{x_1-x_2}\\
