Answer:

#13. line QR is 26.

#14. a) x = 2 b) m = 6

Step-by-step explanation:

13. We can use the Pythagorean therom: a^2 + b^2 = c^2

We will substitue PQ for a and PR for b

10^2 + 24^2  = c^2

100 + 576 = c^2

100 + 576 = 676

Then, we find the square root of 676, which is 26.

14. a) 3(2x -1) = 9

we first use distributive property:

6x - 3 = 9

then we add 3 to both sides to counteract the -3:

6x = 12

we divide both sides by 6 to get x alone:

x = 2

b) 3m - 12 = 6

we add 12 to both sides to counteract the -12:

3m = 18

we divide both sides by 3:

m = 6

A Spanish teacher informed her class that she would be giving 4 quizzes each month. Write an equation that shows the relationship between the number of months elapsed, x, and the total number of quizzes, y.

Answers

Answer:

y = 4x

Step-by-step explanation:

Since there are going to be four quizzes a month (x), we know that we will multiply the number of months (x) by the number of quizzes (4). However, because we don't know how many months there are, we can define the months as (x), and instead put the total (y) is equal to the number of quizzes per month (4), multiplied by the number of months (x). Out final result is

(y = 4x)

Complementary angles are two angles whose sum = 90°

x = 45/3

x = 15°

A tennis racket with a price of $180 is subject to a sales tax of 7%. What is the total
price of the racket?
$192.60
$187

Answers

The total price of the racket is $192.60 (first option).

What is the total price?

A tax is a compulsory amount of money that is levied by the government or an agency of the government on goods and services. A sales tax is levied on the sales of goods and services.

The total price of the racket would include the amount of tax that would be paid.

Total price = (1 + tax/100) x initial price

Total price = (1 + 7%/100) x $180

Total price = (1 + 0.07) x $180

Total price = (1,07 x $180)  

Total price = $192.60

En un parqueadero hay 50 vehículos. Pero si contamos sus llantas hay 140.¿Cuántos carros y motos hay? Por favor alguien que me ayude este tema es de matemáticas problemas lineales 2x2

Answers

Answer:

Carros = 20

Motos = 30

Step-by-step explanation:

Carros = x

Motos = y

x + y = 50

4x + 2y = 140

x = 50 - y

4 (50-y) + 2y = 140 (substitución)

200 - 4y + 2y = 140

- 2y = 140 - 200

y = -60/-2

y = 30

x + 30 = 50

x = 50-30

x = 20
