Answer: 4x54=216
Step-by-step explanation:
Well you don’t need to count in mr smiths math class because all the classes has 54 so um I did 4x54 hoped this helped :)
Answer:
50 ft
Step-by-step explanation:
The sum of length and width is half the perimeter, so ...
L + W = P/2
L = P/2 - W = (180 ft)/2 - 40 ft = 50 ft
The length of the garden is 50 ft.
Answer:
3x+4y
Step-by-step explanation:
If you buy 2 M&Ms, you would get $6. Plugging in 2 for x would indeed give us 6, which makes sense.
If you buy 2 KitKats, you would get $8. Plugging in 2 for y would indeed give us 8, which makes sense.
Therefore, we can plug in x and y for the unknowns and add them together to find the total amount spent on both candies.
Answer:
3/50.
Step-by-step explanation:
There are 10 marbles in the bag.
Probability( a green marble) = 2/10 = 1/5.
Now we replace the green marble in the bag so it contains 10 marbles again.
Probabilty(a yellow marble) = 3/10.
So Probability(Choosing a green then a red with repeacemen)
= 1/5 * 3/10
= 3/50.
Some things to know
point slope form: for a line passing through (x1,y1) and the slope is m
y-y1=m(x-x1)
horizontal lines are y=constant
y=mx+b, m is slope and b is y intercept
the slope of the line that passes through the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
1.
y-2=2/3(x-(-3))
y-2=2/3(x+3)
2.
find slope
(-2-3)/(6-(-4))=(-5)/(6+4)=-5/10=-1/2
a point isi (-4,3) and slope is -1/2
y-3=-1/2(x-(-4))
y-3=-1/2(x+4)
3.
yintercept of 2 means (0,2) is a point
find slope between (0,2) and (12,4)
(4-2)/(12-0)=2/12=1/6
a point is (12,4)
y-4=1/6(x-12)
4.
horizontal is y=something
(x,y)
(-2,-9)
we have y=-9
y=-9 is the equaiton
5.
y=-2x+3
y=mx+b
-2 is slope
a point is (-6,2)
y-2=-2(x-(-6))
y-2=-2(x+6)
