Answer:

Let x = # of commercials

y = # of movies

System of Equations:

x + y = 90

40x + 110y = 500

Step-by-step explanation:

We have to set our variables before we start solving. After setting the variables, we can set up the equations. If x = # of commercials and y = # of movies, then we can assume x + y = 90, as there have been a total of 90 commercials and movies played altogether. Then, we know that their worth is $500, so the price of all the commercials played and the price of all the movies played (which is 40x + 110y) sum to $500.

(I've just answered this question from your previous post. Unless my answer was wrong, I don't see why you would repost the exact same question.)

Step-by-step explanation:

i hope this makes sense lol. You can see it's a linear since it decrease at a steady rate. so you have to find the slope and find the y- intercept

Find the value of x that makes lines u and v parallel

gogolik [260]

Answer:

x = 4 for Lines U and V to be parallel

Skills needed: HS Geo, Angle Theorems, Equations

Step-by-step explanation:

1) We see that there are two angle measures given to us. There is an angle marked with the measure of $130$ °, and the other is marked with ( $33x-2$ )°.

First of all, these two angles are categorized alternate interior angles. They are on alternate sides of the transversal, and are within the two lines (not on the outer side of the lines). I will add an image for reference regarding this idea.
If 2 lines are parallel, alternate interior angles are congruent. This means that: $33x-2=130$

2) Solving this equation is fairly straightforward.

$33x-2+2=130+2$ (add 2 to both sides in order to get the $33x$ by itself.
$33x\div33=132\div33$ (to get $x$ by itself)
132 divided by 33 is 4, and 33x divided by 33 is x, so $x=4$
