Simplify both sides of the equation
-25(x-4)=-55(x-10)
(-25)(x) + (-25)(-4)=(-55)(x) + (-55) (-10)
Distribute
-25x+100=-55x+550
Add 55x to both sides
-25x+100+55x=-55x+550+55x
30x+100-100=550-100
subtract 100 from both sides
30x+100-100=550-100
30x=450
divide both sides by 30
30x/30=450/30
x= 15
The value of x is 15
I hope that's help you my friend !
Factored form - x= -1/2, -5/4
I'd say (a) = 52.5 minutes or 52 minutes and 30 second
(b) = 45 minutes
There are 3 sticks because:
4 sticks is the total and when you take away 1 stick, it is
4 - 1, which equals 3 sticks
So, the answer is 3 sticks are left.
Question: If u are in high school, why did you ask this question? You already know 4-1=3. Im guessing it was either a joke, or u were helping other people get points. If it is the second one, thx!!
