The solution to the problem is as follows:


5x^2 + 9x - 2 / x^2 + 12x + 20 multiply x^2 + 17x + 70 / 15x - 3 
<span>
=[(5x-1)(x+2)]/[(x+2)(x+10)] multiply [(x+7)(x+10)]/[3(5x-1)] </span>
<span>
=(x+7)/3
</span>

The revenue generated by the band is given by the expression 50x+150y.
Dafna1 [17]

Answer:

They exceed their goal by $150.

Step-by-step explanation:

If x = weekday shows and y = weekend shows, then

50(15) + 150(6)

750 + 900 = 1650

1650 - 1500 = 150

In a trivia game, Levi answered eight questions correctly out of 10 turns in the game. He then answered the next three questions
vaieri [72.5K]

Based on the fact that he added three correct questions, Levi is wrong in assuming that the ratio of correct answers to total answers remained the same.

<h3>Why is Levi wrong?</h3><h3 />

When the total number of variables being compared in a ratio changes, the ratio itself will change.

This means that Levi is wrong in assuming that the ratio of correct answers to total questions will remain the same after he added 3 questions to both measures.

The first ratio of correct answers to questions was:
8 : 10

4 : 5

After three correct answers are added, it becomes:

11 : 13

This is not the same as the first ratio of 4 : 5.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Daniel [21]
Answer: x = 11 degrees

Step by step explanation:
Triangle rule states that all angles of a trundle must equal to 180 degrees. So we have two known angles, therefore we can subtract them from the 180 degree total.
180-109-43
=28
Now to solve for x we have the equation
4x-16=28
We add 16 to both sides to isolate x
4x=44
Now we divide each side by 4 to get rid of the coefficient
x=11
