We can't tell where your parentheses are, so we don't know if you said 5 (x+2) = 17 or (5x+2)=17. ... If it's the first one, then x+2=17/5 and x=7/5 or 1.4. / / / If it's the second one, then 5x=15 and x=3. I guess it must be the second one, because 1.4 is not one of the choices. Ah the sleaze of math by multiple choice.

Answer:

ADB and ABC are similar

x = 8

Step-by-step explanation:

hypotenuse in ADB = $\sqrt{4^2 + 2^2 } = \sqrt{20}$

since two triangles are similar,

$\frac{2+x}{\sqrt{20} } = \frac{\sqrt{20}}{2}$

solving for x, x=8

Thomas brings over 1/2 of his marble collection. He divides these marbles equally among 3 friends. What fraction of Thomas's ent

aleksley [76]

Answer:

Each of the three friends will get one-sixth of the Thomas's enitre marble collection.

Step-by-step explanation:

Fraction of the total marble collection brought by Thomas = $\frac{1}{2}$

Now, Thomas divides these marbles equally among his three friends. So, each of the three friends will get one-third of the total marble collection brought by Thomas.

Fraction of total marble collection got by each friend = $\frac{1}{3} \;of\;fraction\;of\;total\;marble\;collection\;brought\;by\;Thomas$

= $\frac{1}{3}\times\frac{1}{2}=\frac{1}{6}$

∴ Each of the three friends of Thomas will get one-sixth of his entire collection of marbles.
