Answer:
The system of equations is
Step-by-step explanation:
Let
x ----> the number of minutes of calling time
y ----> the monthly cost of the calling plan
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
In this problem
Plan A
substitute
----> equation A
Plan B
substitute
----> equation B
therefore
The system of equations is
a) To find the volume of a cube, you cube the side length.
So, that will be V = 9/2³ = 729/8 in³.
b) To find the volume of a rectangular prism, you multiply the length by the width by the height.
So, that is V = 18 * 9 * 9/2 = 729 in³.
c) To find how many times the smaller box can go into the larger one, you divide the larger one's volume over the smaller one's.
That is <em>729/(729/8) = 729*8/729 = </em><em>8 boxes</em><em>.</em>
Answer:
hay 10 billetes de 2000
hay 4 billetes de 5000
Step-by-step explanation:
Planteamos las siguientes ecuaciones...:
x= billetes de 2000
y= billetes de 5000
ecuaciones :
1) x+y = 14
2) 2000x + 5000y =40000
despejamos primera ecuacion y remplazamos en segunda :
1) x= 14-y
2) 2000(14-y) + 5000y = 40000
28000- 2000y+5000y = 40000
3000y= 40000 - 28000
y= 4
reemplazamos este valor en primera ecuacion:
x+y = 14
x+ 4= 14
x= 10
ahora reemplazamo valor de X y valor de Y
2000(10) + 5000(4) =40000
40000 =40000
hay 10 billetes de 2000
hay 4 billetes de 5000

The answer is no.
A dilation is when a shape is scaled up or down to create a similar shape. The only thing that changes is the lengths of the sides. The angles will stay the same.
In this case, the original has angles 54, 29, and 97.
After the transformation the triangle has the angles 29, 59, and 92.
Answer:
3 hours
Step-by-step explanation:
y = mx + b
for each hour you are charged 15 dollars. for every 1 hour, you are charged $15.
y = 15x
you must also add the base fee of 35
y = 15x + 35
if you know that y = 80,
80 = 15x + 35
solve for x
x = 3
