The graph shows four points on the line and the triangles resulting from sketching on the rise and run from one point to the nex

t. Viewing the graph or R-value as a transversal to the rise and run segments, are the two pairs of corresponding angles along the transversal congruent? Explain.

May has 5 cups of dough. It takes 1/3 cup of dough to make one dinner roll. How many dinner rolls can she make with the dough sh
BabaBlast [244]

Answer:

15 Rolls.

Step-by-step explanation:

This problem is one that can be solved simply by dividing.

Take 5, and divide that by 1/3.

However, you can't just do this. The way I did it was by turning 5 into 5/1. Then, Multiply by the reciprocal, which would be 5 x 3, which equals 15.

Use substitution to solve each system of equations <br> Y=2x-2<br> Y=x+2
Alik [6]
Y = 2x - 2 ⇒ 2x - y = 2  ⇒ 2x - y = 2
y = x + 2  ⇒ x - y = -2   ⇒ <u>2x - 2y = -4</u>
                                                 <u>3y</u> = <u>6</u> 
                                                  3     3
                                                   y = 2
                                            2x - 6 = 2
                                            <u>      +6   +6</u>
                                                 <u>2x</u> = <u>8</u>
                                                  2     2
                                                   x = 4
                                             (x, y) = (4, 2)

In a movie theater, the number of seats in a row is 8 greater than the total number of rows. How many rows are in the movie thea
Harman [31]

Answer:

26 rows

Step-by-step explanation:

this is like a rectangle length×width situation.

seats per row = s

number of rows = r

s × r = 884

s = r + 8

so, we can use e.g. the second equation in the first :

(r + 8) × r = 884

r² + 8r = 884

r² + 8r - 884 = 0

the general solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = r

a = 1

b = 8

c = -884

r = (-8 ± sqrt(8² - 4×1×-884))/(2×1) =

= (-8 ± sqrt(64 + 3536))/2 = (-8 ± sqrt(3600))/2 =

= (-8 ± 60)/2 = -4 ± 30

r1 = -4 + 30 = 26

r2 = -4 - 30 = -34

a negative number did not make any sense for the number of rows, so r = 26 is our answer.

What is m∠BEC ?<br><br><br> Enter your answer in the box.
Stels [109]
We are able to set 4x+32 equal to 6x-8 because these are congruent vertical angles

4x+32=6x-8
4x+40=6x (add 8 to both sides)
40=2x (subtract 4x from both sides)
X=20 (divide both sides by 2)

Then we plug in 20 for x into 6x-8 to find the answer

6(20)-8
=120-8
=112

Hope this helps!
