The answer would be 4 hours 29 minutes (Total travelling time) 4.48 hours.
Hope this helps. :)
Answer:
70x + 490 = 40x +670
Step-by-step explanation:
Let's start with Tom's equation. So we'll start with y=mx+b. b is the amount Tom has started with(aka $490), m is the gain(aka how much money is he getting that month? it's $70) and x is month, plug in the values and you'll get:
y = 70x + 490
Okay do the same thing for Tammy, just change the values accordingly:
y = 40x + 670
Now when are they going to have the same amount of money? This will be the equation to show when they will have the same amount of money. We'll use equal values method:
70x + 490 = 40x +670
subtract 490 and 40x from both sides
30x = 180
divide both sides by 30
x = 6
So, we know now that in 6 months they will have the same amount of money.
So we are to merge the two equations into one, since both of the equations are equal to y. a = b, b = c therefore, a = c.
We are to isolate x.
The value of x is approximately, 1.9047m
Then, substitute the value of x from
y = 5.862m
Round up, then the answer would be D.
Answer:
Equation=$140+$85=$225
Step-by-step explanation:
If she sold her bike for $140 less than she paid for it, and she sold it for $85, you add 140 to 85 to get out much she paid for. To check your answer do 225-140=85.
Given:
400 centimeters
convert to meters.
1 meter is equal to 100 centimeters.
400 cm * 1m/100cm = 400m/100 = 4 meters.
There are 4 meters in 400 centimeters.
