Answer:

PEMDAS” (parenthesis, exponents, multiplication, division, addition, subtraction) to help you remember? Memorable acronyms aren't the only way to memorize concepts.

Step-by-step explanation: -> 3 x 2 +( 4 - 1) = ??

always when you see these in your equation you always start with these>>>(4-1=3) then 3x2=6 then you add that then you get 9

9 is your answer hope this helps

Answer:

The answer is 9.

Step-by-step explanation:

PEDMAS stands for :

$\purple\star$ P = Parentheses
$\purple\star$ E = Exponents
$\purple\star$ M = Multiplication
$\purple\star$ D = Division
$\purple\star$ A = Addition
$\purple\star$ S = Subtraction

To solve the given equation we will follow the PEDMAS rule.

$\begin{gathered}\qquad{\twoheadrightarrow{\sf{3 \times 2 + (4 - 1)}}} \\ \\ \qquad{\twoheadrightarrow{\sf{3 \times 2 + (3)}}} \\ \\ \qquad{\twoheadrightarrow{\sf{3 \times 2 + 3}}} \\ \\ \qquad{\twoheadrightarrow{\sf{6+ 3}}} \\ \\ \qquad{\twoheadrightarrow{\sf{9}}} \\ \\ \qquad{\star\underline{\boxed{\tt \pink{ \: 9 \: }}}}\end{gathered}$

Hence, the answer is 9.

What is the slope of the line that passes through the points ( − 1 , − 7 ) (−1,−7) and ( 1 , − 13 ) (1,−13)? Write your answer i

Paraphin [41]

Answer:

$y = -3x -10$

Step-by-step explanation:

Slope-intercept formula: $\frac{y_2-y_2}{x_2-x_1}$

Find slope of (−1, −7) and (1, -13)

$\frac{y_2-y_2}{x_2-x_1}\\\\\\frac{-13-(-7)}{1-(-1)}\\\\\\frac{-6}{2}\\\\\-3$

$y = mx + b$

$y = -3x +b$

$y = -3x +b\\-7 = -3(-1) + b\\-7 = 3 +b\\-3 -3\\-10 = b$

$y = -3x -10$

Hope this helps!

What is the slope of the line?

Leya [2.2K]

Answer:

The slope of the line is -3

Step-by-step explanation:

I chose the points (-2,3) and (0,-3)

The slope formula: m= $\frac{y_2-y_1}{x_2-x_1}$

$\frac{-3-3}{0-(-2)}$ ==> $\frac{-3-3}{0+2}$ ==> $\frac{-6}{2}$ = $-3$

Our final answer is -3.

Hope that helps!

What angle is this and explain

REY [17]

The measures of the angles are 59 degrees

<h3>How to determine the value of the angles?</h3>

The angles are given as:

Angle 1 = 2x + 17

Angle 2 = 3x - 4

By the interior angle theorem, the angles are congruent

So, we have

Angle 1 = Angle 2

Substitute the known values in the above equation

2x + 17= 3x - 4

Collect the like terms

3x - 2x = 17 + 4

Evaluate the like terms

x = 21

Substitute x = 21 in Angle 1 = 2x + 17

Angle 1 = 2 * 21 + 17

Evaluate

Angle 1 = 59

This means that

Angle 1 = Angle 2 = 59

Hence, the measures of the angles are 59 degrees

Otis plans to make 3 batches of sidewalk chalk How much plaster of paris does he need

den301095 [7]

Answer:

$4\frac{1}{2}$ cups plaster of paris.

Step-by-step explanation:

Given:

for one batch of sidewalk chalk = $1\frac{1}{2}$ cup plaster of paris.

Number of bathes = 3

We need to find quantity of plaster of paris.

Solution:

For making 1 batch of sidewalk chalk = $1\frac{1}{2}$ cup plaster of paris.

For making 3 batches of sidewalk chalk = $3\times 1\frac{1}{2}$ cup plaster of paris.

$= 3\times \frac{2\times 1+1}{2}$

$= 3\times \frac{2+1}{2}$

$= 3\times \frac{3}{2}$

$= \frac{3\times 3}{2}$

$= \frac{9}{2}$

$=4\frac{1}{2}$

Therefore, he needed $4\frac{1}{2}$ cups plaster of paris.
