Idk what it has to do with simplifying but what I would do is multiply 1 times 3. That gives u 3. Then add Ben's one hour and Brooke's 3 hours together. That gives u 4 hours total.
Answer:
d = 10/72
Step-by-step explanation:
c and d vary inversely
c = k/d
Where,
k = constant of proportionality
d = 2/9 when c = 5
c = k/d
5 = k ÷ 2/9
5 = k × 9/2
5 = 9k/2
Cross product
5*2 = 9k
10 = 9k
k = 10/9
c = k/d
c = 10/9 ÷ d
c = 10/9 × 1/d
c = 10/9d
find d when c = 8
c = 10/9d
8 = 10/9d
Cross product
8*9d = 10
72d = 10
d = 10/72
The increase of the radius is a linear increase since we have the constant rate of 0.07 inches per second
The equation for a linear growth/decay is given by the form
where
is the rate of increase and
is the value of
when
We have
when
So the equation is 
The length of the radius when
seconds is
inches
Answer:
Step-by-step explanation:
First, isolate the variables onto one side of the equation.
2x + 3 = x - 4
(subtract x)
x + 3 = -4
Then, remove any remaining numbers.
(subtract 3)
x = -7
I hope this helps!
