Answer:
28
Step-by-step explanation:
42/6 = 7
7 x 4 = 28
Answer:
No
Step-by-step explanation:
Replace x with the given c value to get y = 5 + 2 which becomes y = 7
Since y is 3 in the given solution and not 7 it cannot be a solution.
Answer:
The number of green marbles are 36.
Step-by-step explanation:
Given:
Total number of marble bag contains is 42.
The number of green marbles is 6 more than 5 times the number of red marbles.
Let the number of red marbles be
.
So, the number of green marbles = ![6+5x](https://tex.z-dn.net/?f=6%2B5x)
Now, to get the number of green marbles.
According to question:
![x+(6+5x)=42](https://tex.z-dn.net/?f=x%2B%286%2B5x%29%3D42)
![6x+6=42](https://tex.z-dn.net/?f=6x%2B6%3D42)
Subtracting 6 in both sides :
![6x+6-6=42-6](https://tex.z-dn.net/?f=6x%2B6-6%3D42-6)
![6x=36](https://tex.z-dn.net/?f=6x%3D36)
Now, by dividing 6 on both sides:
![6x\div 6=36\div 6](https://tex.z-dn.net/?f=6x%5Cdiv%206%3D36%5Cdiv%206)
![x=6](https://tex.z-dn.net/?f=x%3D6)
The number of red marbles are 6.
And, the number of green marbles are
=
=![6+30](https://tex.z-dn.net/?f=6%2B30)
= ![36](https://tex.z-dn.net/?f=36)
Therefore, the number of green marbles are 36.
Answer:
y = 1/2x
Step-by-step explanation:
y-intercept is (0, 0)
pick any point, let's say (-4, -1). Let's apply rise over run, rise up 2 points then run 4 points over to arrive at (4, 1). So, your slope is 2/4 which simplify to 1/2.
Equation of line:
y = mx + b
m is your slope
b is y-intercept
y = 1/2x + 0 same as y = 1/2x
