Answer:

0 = 2

No solution

Step-by-step explanation:

$-2(t-4)=10-2t\\\\\mathrm{Expand\:}-2\left(t-4\right):\quad -2t+8\\\\-2t+8=10-2t\\\\\mathrm{Subtract\:}8\mathrm{\:from\:both\:sides}\\\\-2t+8-8=10-2t-8\\\\Simplify\\\\-2t=-2t+2\\\\\mathrm{Add\:}2t\mathrm{\:to\:both\:sides}\\\\-2t+2t=-2t+2+2t\\\\Simplify\\\\0=2\\\\\mathrm{The\:sides\:are\:not\:equal}\\\\\mathrm{No\:Solution}$

Answer:

The cost is a fixed $2, plus $3.25 for any additional hour.

Then if you rent it for x hours, the cost is:

c(x) = $2 + $3.25*x

Is this situation continuous or discrete?

Yes, it is discrete, because x is "the number of hours"

so if you rent it for 1.30 hours, they will say "ok, this is equivalent to two hours".

This means that while the values of x are continuous, the possible costs are:

{$2, $2 + $3.25, $2 + 2*$3.25, ....}

Which is a discrete set.

Then the sign for 1 to 5 hours will be:

1 hour ---------- $2 + $3.25 = $5.25

2 hours -------- $2 + 2*$3.25 = $8.50

3 hours--------- $2 + 3*$3.25 = $11.75

4 hours--------- $2 + 4*$3.25 = $15

5 hours -------- $2 + 5*$3.25 = $18.25

In the other park the cost is only $4 for each hour (no fixed cost) then the total cost for x hours is:

c(x) = $4*x

Now, which option is better?

If we look at the costs for different numbers of hours for this other equation, we have:

1 hour ----- $4

2 hours ---- 2*$4 = $8

3 hours ----- 3*$4 = $12

4 hours ------ 4*$4 = $16

Then: if you want to skate 2 hours or less, Skate City is cheaper, if you want to skate more than that, kate Days is cheaper.

This happens because the first one has a smaller slope, meaning that is larger at first, but as x grows the price does not grow as much as in Skate City

For thanksgiving, you made 32 cupcakes. How many cupcakes were leftover if your family ate 3/4 of them?

Anvisha [2.4K]

All you need to do is divide 32 by 4.

32/4= 8

So, 3*8= 24 (that is 3/4 of the cupcakes)

32-24= 8

8 is the answer.

I hope this helps!

Step-by-step explanation:

We can write 2 simultaneous equation and solve for weight of each box.

Let weight of large box be l and small box be s.

"3 large boxes and 5 small boxes has a total weight of 116 kilograms":

$3l+5s=116$
