1 Subtract 22 from both sides
13x=4x+38-213x=4x+38−2
2 Simplify 4x+38-24x+38−2 to 4x+364x+36
13x=4x+3613x=4x+36
3 Subtract 4x4x from both sides
13x-4x=3613x−4x=36
4 Simplify 13x-4x13x−4x to 9x9x
9x=369x=36
5 Divide both sides by 99
x=\frac{36}{9}x=
9
36
6 Simplify \frac{36}{9}
9
36
to 44
x=4x=4
Answer:
<h2>181 440</h2>
Step-by-step explanation:
We have 9 choices for Choosing the first object
8 choices for Choosing the 2nd object
.
.
.
3 choices for Choosing the seventh object
Therefore if we want to choose7 objects without replacement from 9 objects we have : 9×8×7×6×5×4×3 = 181 440
Also ,we can calculate it this way :
9P7 = 181 440
Answer:
sqrt(2x/a) = t
Step-by-step explanation:
X = 1/2at^2
Multiply by 2 on each side
2x = 2*1/2at^2
2x =at^2
Divide by a
2x/a=a/a t^2
2x/a =t^2
Take the square root of each side
sqrt(2x/a) =sqrt(t^2)
sqrt(2x/a) = t
