So since you gave all of the equations of everyone's amount that they put in, it saves some work.
Let's add up everyone's contribution and then solve for x:
Then since we know the television costs $2,000, we can set this expression equal to that and simplify terms. Then we can solve for x:
So since Ronnie put in 'x', we can say that Ronnie paid $70.
Since Mark put in '2x + 500', we can plug in 70 for x to find that Mark paid $640.
And since Lisa put in '650 + 2x + 500', we can plug in 70 for x again to find that Lisa paid $1,290.
Answer: Alberto traveled 792 miles as total distance.
Step-by-step explanation:
Since we have given that
Distance rode by the train = 198 miles
Number of times round tip in last month = 4 times
We need to find the total distance that Alberto traveled.
So, Total distance that Alberto traveled is given by
Hence, Alberto traveled 792 miles as total distance.
Answer:
Any number by ten is the number and add how many 0's there are in an equation at the end. If you are doing it with decimals you would move one space to the right or left depending if it i negative or positive.
Step-by-step explanation:
If you times a number by ten and go the long way it will still equal up to the same number if you just add the amount of zero's it has in the equation to the end. Example's: 10x10=100 & 11x10=110.
Answer:
6250
Step-by-step explanation:
Hope the answer is correct.
X² + 5x + 6.
When the x² is alone, you just think of two numbers that add up to give 5 and multiply to give 6.
those are 2 and 3.
<span>x² + 5x + 6
</span>
<span>x² + 2x + 3x + 6
</span>
x(x + 2) + 3(x + 2)
(x + 2)(x + 3)
