It took jerry 3 4/5 hours to get to his mothers house .He walked for 2/5 hours to the train station and then took a bus.how much

frez [133]

Jerry walked for 2/5 hours to the train station and the whole way took him 3 4/5 hours, then he had to go by bus

$3\dfrac{4}{5} -\dfrac{2}{5}$ hours.

First consider fractions $\dfrac{4}{5}$ and $\dfrac{2}{5}$ . Subtracting from first fraction second fraction you have:

$\dfrac{4}{5} -\dfrac{2}{5}=\dfrac{4-2}{5} =\dfrac{2}{5}$ .

Then add to the whole number this fraction and get

$3+\dfrac{2}{5} =3\dfrac{2}{5}$ hours.

Answer: Jerry spent riding on the bus $3\dfrac{2}{5}$ hours.

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

$c^2=a^2+b^2$

a,b - legs

c - hypotenuse

We have c = x, a = 7 and b = 24. Substitute:

$x^2=7^2+24^2\\\\x^2=49+576\\\\x^2=625\to x=\sqrt{625}\\\\x=25$

$(4x^2+8x-2)-(2x^2-4x+3)\\\\=4x^2+8x-2-2x^2+4x-3\\\\=(4x^2-2x^2)+(8x+4x)+(-2-3)\\\\=\boxed{2x^2+12x-5}$
