Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>
First, you have to find the LCD. The LCD of 4 and 7 is 28, so you rewrite the fraction:
7/28
4/28
Then you add them.
Answer:
y=(-4/3)x+2 = -1.33x+2
Step-by-step explanation:
we have two points:
(3,-2) and (0,2) given from the graph.
we know the equation of the line is
y=mx+b
m=slope
m=(y2-y1)/(x2-x1)
m=(2-(-2))/(0-3)
so we have the slope is
m=4/-3
m=-4/3
-4/3=-1.3333
we need to find "b"
using the point (0,2)
we have
2=m*0+b
2=b
finally we have
the answer is y=(-4/3)x+2
