3x - 5 = 10 or 3 × 5 - 5 = 10


y ÷ x - 4 = 14 or 36 ÷ 2 - 4 = 14

2) 3x-5=10
You add 5 on both sides, so that the fives cancels.
3x-5=10
+5 +5
That leaves you with
3x=15
Then you have to get the x alone. You divide the three on both sides.
3x/3=15/3
The threes cancel out, so you now have
x=5

3) x
— -4=14
3
On this one you need to add 4 on both sides to cancel it out.
+4 +4
Since you just canceled the 4’s out that makes the equation...
X
— =18
3
Now you want to get x alone so you have to find a way to cancel the threes out. You times the three to the x/3.
3 X
— =18
3
What you do to one side you have to do to the other.
3 X
— =18x3
3
That leaves you with...
X=54

Hope this helped. Sorry if I’m late

First rectangle:
Has 3 cubes in each 5 layers, and imagine it, so we have all dimension needed which is:
l=3 unit
w=1 unit
h=5 unit.
V=l×w×h
V=3×1×5
V=15 cubic inches.

Second rectangular:
Doing the same like that to get:
l=5 unit
w=1 unit
h=3 unit
V=15 cubic inches. As a result, there are no prism that are greater to each other, which mean that they have the same volume of 15 cubic inches. Hope it help!

The school soccer coach records the number of goals some players have scored so far this season. The dot plot of the number of g
yuradex [85]

Answer:

the means absolute deviation is 1.8

the striking deviation is 7

(it is because the data point on the far right of the graph)

Step-by-step explanation:

calculate the absolute deviation:

1.  calculate the mean (add all numbers and divide by 10) = 2.6

2.  find the absolute value of each

2.6 - 0 = 2.6

2.6 - 1 = 1.6 (you have 1's 4 times so each one will be 1.6)

2.6 - 3 = 0.4

2.6 - 4 = 1.4 (you have 4's 3 times)

2.6 - 7 = 4.4

3.  Then add all of those values together

2.6 + 1.6 + 1.6 + 1.6 +  1.6 + 0.4 + 1.4 + 1.4 + 1.4 + 7.4 = 18

4.  find the mean of the difference

18/10 = 1.8
