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

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.
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)

angle A and angle B are complementary angles. The measure of angle A is (3x)"
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
3x = 45
x = 45/3
x = 15°
a model of a ship is made to a scale of 1:200
the surface area of the model is 7500 cm²
calculate the surface area of the ship, giving your answer in square meters
The surface area of the ship is 1500000 cm²
Scaling is used to either increase or decrease the size of a figure so as to create an image.
Given a scale of 1:200, this means that it is a scaling down (decrease in size) of the ship to create a model.
The surface area of the model is 7500 cm², hence that of the ship is:
Surface area of ship * (1 : 200) = surface area of model
Surface area of ship = surface area of model * 200 = 7500 * 200 = 1500000 cm²
The surface area of the ship is 1500000 cm²

Rushawn lined up the interior angles of the triangle along line p below.
When the measure of angle C decreases, what happens to the measures of angles A and B on line p?
A. Both sections increase.
B. Both sections decrease.
C. One section increases, and the other section decreases.
D. What will happen to the individual sections cannot be determined, but the size of the two sections together increases.
answers/w explanation ✅ Nonsense answers, that's not the question I didn't ask for will be reported.
D is the correct option as the decrease in angle C will make angle A increase thus making the section with both angle A and B to increase.

D :))

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

Answer:
5
Step-by-step explanation:
The whole angle is 180 degrees.
90 degrees is already taken by the angle dividing the two vertical angles.
So you have 90 degrees left. then you have to subtract 49 from 90 to get the angle of '5t+6'.
So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.

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
