Answer:
1.36mph
Step-by-step explanation:
The escalator is moving at 2ft/s, lets convert this to miles/second.
2ft/s = 0.000378788miles/s.
Now that we have the miles/second lets multiply this value by 3600 to get the miles/h, because there are 3600 seconds in an hour.
2ft/s=1.3636368miles/h
Or approximately 1.36miles/h.
Answer:
(2a,2b)
(-4a,b)
Step-by-step explanation:
for the first one
the x value of coordinate L is going to be twice the value of the x coordinate of k (a)
That being said the x value of L = 2a
The y value of L is going to be half the value of the y value of coordinate A ( 4b )
4b/2=2b so the y value of coordinate L is 2b
now we put the values as an ordered pair
The answer would be (2a,2b)
The answer of average rate o change is 2. Hope it help!
In order to solve this equation you could use guess and check with multiple choice, or you can set up a system of equations.
First we must define our variables:
x=price of taco
y=price of burrito
Michael bought 4 tacos (4x) and (+) and Burrito (y) for $9.50 (=9.5)
4x+y=9.50
Noah bought two tacos (2x) and (+) three burritos (3y) for (=) $11 (11)
2x+3y=11
To solve this system of equations you can easily see substitution as the easiest method. For substitution we must isolate one variable:
4x+y=9.50
y=-4x+9.5
We can now replace the y in the other equation:
2x+3(-4x+9.5)=11
Then solve this equation to get the price of a taco (x)
2x-12x+28.5=11
-10x=-17.5
x=1.75
The price of a taco would be $1.75
