Put the value of x to the equation.

5+4x=53\\L=5+4(12)=5+48=53;\qquad R=53;\qquad L=R\\\\9x-7=101\\L=9(12)-7=108-7=101;\qquad R=101;\qquad L=R\\\\x+4=10\\L=12+4=16;\qquad R=10;\qquad L\neq R\\\\96\div x=8\\L=96:12=8;\qquad R=8;\qquad L=R

Answer: x + 4 = 10

Can someone help me with this proof
maksim [4K]

Step-by-step explanation:

Given :

Given that lines a and b are parallel, angles 1 and 5 are congruent because they are corresponding angles, and angles 1 and 4 are congruent because they are vertical angles

To find : by which property are angles 4 and 5 congruent

Solution :

We know that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

Also, we know that if two things are equal to the same thing then they are equal to each other . In this case, we can say that if two angles are congruent to a third angle, then they are congruent to each other. As angles 4 and 5 are both congruent to angle 1, they are congruent to each other but angles 4 and 5 are alternate interior angles. So, if parallel lines have a transversal, alternate interior angles are congruent.

Answer:

<em><u>A theater has </u></em><em><u>60 seats</u></em><em><u> in the first row, 68 seats in the second row, 76 seats in the third row,</u></em>

<em><u>and so on in the same i</u></em><em><u>ncreasing pattern</u></em><em><u>. If the theater has</u></em><em><u> 20 rows of seats, how many seats are in the theater?</u></em>

220 seats in the theater.

So if the increasing pattern is +8, and we need to determined how many seats there will be if there where 20 rows, then you would need to multiply.

1. 8 x 20 = 160

2. 160 + 60 = 220

Hannah went on a bike ride on Saturday and Sunday every weekend in November. She recorded the number of miles she rode each time
geniusboy [140]

Looking at the line plot, the longest number of miles is 50, and the shortest is 48 1/4.

Calculating the difference, we have:

\begin{gathered} 50-48\frac{1}{4} \\ =50-(48+\frac{1}{4}) \\ =50-48-\frac{1}{4} \\ =2-\frac{1}{4} \\ =\frac{8}{4}-\frac{1}{4} \\ =\frac{7}{4} \\ =1\frac{3}{4} \end{gathered}

Therefore the correct option is the third one.
