A video rental store charges a $20 membership fee and $2.50 for each video rented.

Write a linear equation to model this situation.

Tell what each variable represents.

Answers

Y=2.5x +20 because x would be the number of times you go, and 20 dollars is the original price

Answer:

2.5x + 20 = y

Step-by-step explanation:

first, assign a variable to each unknown:

since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y

x = number of videos rented

y = total cost

so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.

So, the equation is 2.5x + 20 = y

the answer choices are
a. 32m
b. 225 m
c. 5 m
d. 15 m

Answers

Answer:

d. 15 m

Step-by-step explanation:

hypotenuse (h) = 25 m

base (b) = 20 m

perpendicular (p) = ?

By using Pythagoras theorem we get

p = √h² - b²

= √ 25² - 20²

= √ 225

= √ 15²

= 15 m

Hope it will help :)

Answer:

15

Step-by-step explanation:

according to pythagoras:

25^2 = 20^2 + 15^2

Marco would like to hang a banner over his shoe store. He has two ladders and would like to know how high above the ground each ladder will allow him to place the banner. A 13- foot ladder leans against the building and touches it at a point that is 11.3 feet above the ground.
what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground? Make a sketch and round your answer to the nearest tenth

Answers

13 divided by 11.3 is 1.150442477876106. So 15 by 1.150442477876106 and you get 13.03846162772485. Just round it to the nearest tenth and you get 13.0.

Solve the equation for the red variable

Answers

i think c = p+ r because you firstly have to rearrange the equation so that you isolate the -c. which means you get -c = p-r because you have to change the sign of the r when you switch it. so -c = p-r, but to find c that isn’t minus you need to change the sign on both sides. therefore, the answer should be c = p+r.

2. Solve: 2p+4= - 50

Answers

2p + 4= -50

=> 2p = -50-4

=> 2p = -54

=> p = -54/2

=> p = -27

answer: p=-27

explanation: subtract 4 from both sides,
(4+(-4)) cancels out so you do (-50(-4)) which gives you (-54). Your equation should look like 2p=-54, then you divide 2 from both sides, 2p divided by 2, leaving the “p” variable by itself, while you also divide -54 by 2, which leave you with the final answer: p=-27
