Answer:
Sorry don't know the answer
Answer:
0.33...acre
Step-by-step explanation:
1/4=0.25
3/4=0.75
-------------
0.25/0.75=x/1
cross product
0.75*x=0.25*1
0.75x=0.25
x=0.25/0.75
x=0.3
Answer:
12:16
Step-by-step explanation:
Add the miniature balls.
3 + 9 = 12
There are 16 black marbles in the jar.
Therefore, the ratio of miniature balls to the number of black marbles is 12:16.
slope intercept form
y=mx+b
where m is the slope and b is the y intercept
if we change from point slope form
y-y1 = m(x-x1)
we distribute
y-y1 = mx -x*x1
then add y1 to each side
y = mx -x*x1+y1
remember x and y are variables and should stay in the equation
m,x1,y1 are numbers from the problem
you may have to calculate the slope (m) from the formula
m = (y2-y1)/(x2-x1) from two points on the line
