Answer:
4
Step-by-step explanation:
Based on the information given in the question, the inequality which can be used to determine x, the number of people who can go to the amusement park will be:
8 + 38(x) ≤ 160
8 + 38x ≤ 160
38x ≤ 160 - 8
38x ≤ 152
x ≤ 152/38
x ≤ 4
The number of people that can go to the amusement park will be at most 4.
Hence the answer is 4.
Un camión traslada 12 vehículos. Algunos son autos y otros son camionetas. Cada auto tiene una masa de 2 toneladas y cada camioneta de 3 toneladas. En total, el camión lleva una carga de 33 toneladas.
Escribe un sistema de ecuaciones que permita calcular cuántos vehículos de cada tipo traslada el camión. Usa a para representar la cantidad de autos y c para representar la cantidad de camionetas que traslada el camión.
El sistema de ecuaciones queda descrita por las siguientes expresiones:
[tex]a+c = 12[/tex]
[tex]2\cdot a + 3\cdot c = 33[/tex]
Donde [tex]a[/tex] y [tex]c[/tex] son las cantidades de autos y camionetas.
El enunciado es equivalente a un sistema de dos ecuaciones lineales con dos incógnitas. Una ecuación para la cantidad de vehículos trasladados por el camión y otra ecuación para la masa total trasladada:
[tex]a+c = 12[/tex] (1)
[tex]2\cdot a + 3\cdot c = 33[/tex] (2)
Donde:
[tex]a[/tex] - Cantidad de autos.[tex]c[/tex] - Cantidad de camionetas.El sistema de ecuaciones queda descrita por las siguientes expresiones:
[tex]a+c = 12[/tex]
[tex]2\cdot a + 3\cdot c = 33[/tex]
Donde [tex]a[/tex] y [tex]c[/tex] son las cantidades de autos y camionetas.

13 What is the equation of the line that has a slope of -3 and passes through the point (4,6)?
A-3x+y=-14
B -3x+y=-6
C 3x+y=18
D 3x+y=22
Step-by-step explanation:
the general equation of a line is
y = ax + b
a is the slope of the line.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
6 = -3×4 + b = -12 + b
18 = b
so, the full line equation is
y = -3x + 18
which is answer C : 3x + y = 18

8x-1/3y=16
9514 1404 393
Answer:
x = 2
Step-by-step explanation:
You find the x-intercept by setting y=0 and solving for x.
8x -1/3(0) = 16
8x = 16
x = 16/8 = 2
The x-intercept is 2.
_____
Additional comment
As you can see, the x-intercept is the ratio of the constant to the x-coefficient. The same is true for the y-intercept. It is 16/(-1/3) = -48.

Hello,
A.i. the circumference of a circle is nothing else but its perimeter which formula is π × diameter = π × 2 × radius
Let π = 22/7 ≈ 3.142857, the egyptian approximation
Then if C is the circumference of the circle i., C = 22/7 × 21 = (22 × 21) / 7 = (22× 7×3 )/7 = 22 ×3 = 66 cm
ii. Applying the same formula for the second circle gives us C = 22/7 × 8 = 176/7 ≈ 25.14 meters, rounded to the nearest hundredth...
Good luck !
Answer:
a) 66cm. b) 50.28cm. or 50 2/7cm.
Step-by-step explanation:
The circumference of a circle is C=2πr or C=πd.
π=22/7
a) C=πd
Plugin the diameter.
C=22/7 x 21
=66cm.
b) C=2πr
Plugin the radius.
C=2 x 22/7 x 8
=50.28cm. or 50 2/7cm.
Hope this helps :)
