Answer:
To find the LCD of two rational expressions, we factor the expressions and multiply all of the distinct factors. For instance, if the factored denominators were (x+3)(x+4) ( x + 3 ) ( x + 4 ) and (x+4)(x+5) ( x + 4 ) ( x + 5 ) , then the LCD would be (x+3)(x+4)(x+5) ( x + 3 ) ( x + 4 ) ( x + 5 ) .
If each shirt needs eight buttons you find out what times (×) Eight equals (=) 80
8×10=80
So Eight buttons per shirt
So together they made 10 shirts
but they ask how many Timor made so you do 10 ÷ 2= 5
Timor Made Five (5) Shirts
Inequalities will have a <, >, <=, =>, = or will be worded as "Less than", "greater than", etc.
Equations must have mathematical functions and equal sign.
15=3x is an equation since 3x = 3*x
Finally, expressions are mathematical functions that have no equal signs.
For this, all you need is the velocity formula which is Vf = Vi + at.
Vf = final velocity.
Vi = initial velocity.
a = acceleration
t = time
Vf = Vi + at.
Vf= 0 + (-<span> 9.8 m/sec^</span><span>2) (7s)
</span>
*The 0 says that the original velocity is zero. The - 9.8 m/sec^2 is gravity because there is nothing else acting upon it, and it is negative because it is falling. The 7s is time time.*
All you have to do then, is simplify to get 68.6 m/s which is B.
