Answer:

Addition should be performed last, because of PEMDAS.

Step-by-step explanation:

in pemdas multiply/divide comes before add/subtract so therefore you would multiply 7 x 4 first, even though addition comes before it in the problem.

yuradex [85]

Answer:

15 seats

Step-by-step explanation:

It is given that section A of a theater contains 12 rows of 15 seats each.

Now, it is also given that section B contains only 10 rows it has an equal number of seats the same as section A.

As the number of seats in each row of section A is 15, so, the number of seats in each row of section B will be 15 and the same as section A. (Answer)

Find an input that yields an output of 214. rule: y= -15x+79
Dafna1 [17]

Answer:

          The input  have to be -9 to get output 214 with the rule y=-15x+79

Step-by-step explanation:

x is the input, y is the output so:

214 = -15x + 79

214 - 79 = -15x

15x = -135

 x = -9

Find a linear inequality with the following solution set. Each grid line represents one unit. [asy] size(200); fill((-2,-5)--(5,
kykrilka [37]

The linear inequality of the graph is: -x + 2y + 1 > 0

<h3>How to determine the linear inequality?</h3>

First, we calculate the slope of the dashed line using:

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

Two points on the graph are:

(1, 0) and (3, 1)

The slope (m) is:

m = \frac{1 - 0}{3 - 1}

This gives

m = 0.5

The equation of the line is calculated as:

y = m(x -x_1) + y_1

So, we have;

y = 0.5(x -1) + 0

This gives

y = 0.5x -0.5

Multiply through by 2

2y = x - 1

Now, we convert the equation to an inequality.

The line on the graph is a dashed line. This means that the inequality is either > or <.

Also, the upper region of the graph that is shaded means that the inequality  is >.

So, the equation becomes

2y > x - 1

Rewrite as:

-x + 2y + 1 > 0

So, the linear inequality is: -x + 2y + 1 > 0
