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
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

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 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
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

and the measure of angle B is 45°. What is the value of x?
Answer:
x = 15°
Step-by-step explanation:
Complementary angles are two angles whose sum = 90°
∠A + ∠B = 90°
3x + 45 = 90
