Hello,

1 liter of water in normal conditions has a volume of 1dm^3=(1dm)^3=(10 cm)^3=10^3 cm^3=1000 cm^3

If x is the childrens ticket
$4(x + 1.5) + 5x = 33.30 \\ 4x + 6 + 5x = 33.3 \\ 9x = 33.3 - 6 \\ 9x = 27.3 \\ x = \frac{27.3}{6} \\ x = 4.55$
so that means that the adults ticket is
$x + 1.50 = 4.55 + 1.50 = 6.05$

A cyclist rides at a constant speed of 15 miles per hour. At this speed, about how long would it take the cyclist to ride from F

frozen [14]

We need to find the time taken to travel from Frederick, MD to Baltimore, MD at a speed of 15 miles per hour.

The time taken to travel the distance is 3 hours and 20 minutes.

The shortest route from Frederick to Baltimore is 50.2 miles via the I-70 E.

So we can assume this route will be taken.

Speed of the cyclist = 15 mph

Time is given by distance divided by speed.

So,

$t=\dfrac{50.2}{15}\\\Rightarrow t=3.34\ \text{hours}$

Converting to hours and minutes

$0.34\times 60=20.4\approx 20$

The time taken by the cyclist would be about 3 hours and 20 minutes.

What is the simplified form of ?

Natalija [7]

Let's set it up like this:
$\frac{\frac{x}{3}-\frac{y}{4}}{\frac{x}{4}+\frac{y}{3}}$
Find the LCD, which is 12, and adjust them according to that.
$=\frac{\frac{4x-3y}{12}}{\frac{3x+4y}{12}}$
Divide.
$=\frac{\left(4x-3y\right)\cdot \:12}{12\left(3x+4y\right)}$
Cancel the common factor, which is 12.
$=\frac{4x-3y}{3x+4y}$
That would be our answer!

Let me know if you have any questions regarding this problem!
Thanks!

How do you work out 8x+3=8×+27

Alekssandra [29.7K]

Answer:

No solution

Step-by-step explanation:

8x + 8 = 8x + 27

You then cancel out the 8s. 8 - 8 = 0

Which leaves you with 8 = 27...

Since this is an untrue statement, the answer would be no solution, unless you typed it wrong.
