Answer:
20, 7, 5
Step-by-step explanation:
Range-20, range=most
Mode-7, mode=22-15
Most-5
This is a systems of equations.
s = stamp, e = envelope
Substitute e + 9 for s.
.1(e + 9) + .13e = 2.51
Simplify.
.1e + .9 + .13e = 2.51
Simplify.
.14e + .9 = 2.51
Subtract .9 from both sides.
.14e = 1.61
Divide both sides by .14.
e = 11.5
Now, you can input e into the other equation.
11.5 + 9 = s
Simplify.
20.5 = s
s = 20.5, e = 11.5
Answer:
could you provide the expression?
Step-by-step explanation:
For the first drain the equation you need would be: 2n = 108
for drain B your equation would be: 5n = 108
these are your equations because a number times the amount of water the drain drains per minute will equal 108
to solve use inverse operations and divide 108 by the amount of water the drain drains in one minutes
Drain A- 108/2 = 54
it takes 54 minutes for drain a to empty a pool with 108 gallons of water
Drain B- 108/5 = 21.6
it takes 21.6 minutes for drain b to empty a pool with 108 gallons of water in it<span />
Answer:
Step-by-step explanation:
The average rate of a function 
on interval 
to 
is:
.
and 
here for this problem where 
.
So we will need to evaluate for 
.
To find 
we will replace 
in with 
:
To find 
we will replace in with 
:
So now we need to compute the change in over the change in :
Dividing by is the same as multiplying by 
:
