A small theater can seat 600 people. The number of rows in 10 less than the number of seats in each row. How many seats are in e

Kisachek [45]

Answer:

30 seats

Step-by-step explanation:

To answer this question, we will be assigning values for both rows and seats.

R = Rows

S = Seats

Remember that rs = 600

r = s - 10, plug this equation into rs = 600, and factor it:

s(s-10) = 600

s^2-10s-600 = 0

(x-30)(x+20) = 0

There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.

I need help with this problem<br>

kvv77 [185]

Answer:

Infinitely many solutions

Step-by-step explanation:

Left side:

When you distribute 1/2 to the equation in the parentheses, it will be 3x-3/2.

Right side:

When you distribute 1/4 to the equation in the parentheses, it will be 3x-6/4.

6/4 can be reduced to 3/2 so it'll be 3x-3/2.

This means that the reduced form will be 3x-3/2=3x-3/2

Since the 2 sides have the same equation, there will be infinitely many solutions.

kaheart [24]

A and B are complementary, so A+B. = 90, 3x-8+5x+10=90
8x=88, x= 11
A= 3*11-8=25
B=5x+10=65

Consider the line y=5x -3 Find the equation of the line that is patellar to this line and passes through the point (-8, -3) Cons

Lynna [10]

Answer:

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: $y = 5x+37$

Step-by-step explanation:

Given equation of line is:

$y=5x-3$

The general form of equation of line in slope-intercept form is written as:

$y = mx+b$

Here m(co-efficient of x) is the slope of the line and b is the y-intercept.

Comparing the given equation with the general form we get

m = 5

Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.

Let m1 be the slope of required line parallel to y=5x-3

Then m1=5

Putting in general form

$y = m_1x+b$

$y=5x+b$

To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.

The point is (-8,-3)

$-3 = 5(-8)+b\\-3 = -40+b\\b = -3+40\\b = 37$

Putting the value of b and m1, we get

$y = 5x+37$

Hence,

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: $y = 5x+37$
