Answer:

80 degrees

Step-by-step explanation:

So what you are gonna want to do first is separate that rectangle fro the triangle.

So pretend you have a line in there.

Now the angles 140 degrees will be split into 90 degrees and something else.


140-90= 50 degrees

Now you know that the triangle has two 50 degrees

Add those two together to make it easier

50 + 50 = 100

And a triangle has 180 degrees total

so now minus 100 from 180

180 - 100 = 80

And that means X = 80 degrees

Three-fifths of the students in a room are girls. One-third of the girls have blond hair. One-half of the boys have brown hair.
yan [13]

Answer:

a. Of all the students, \frac{1}{5} are girls with blond hair.

b. Of all the students, \frac{1}{5} are boys without brown hair.

Step-by-step explanation:

a. You know that \frac{3}{5} of the students are girls (This means that \frac{2}{5} of the studes are boys) and \frac{1}{3} of these girls have blond hair.

Then, \frac{1}{3} of \frac{3}{5} is:

(\frac{3}{5})(\frac{1}{3})=\frac{1}{5}

Therefore, of all the students, \frac{1}{5} are girls with blond hair.

b. You know that \frac{1}{2} of the boys have brown hair.

Then, \frac{1}{2} of \frac{2}{5} is:

(\frac{2}{5})(\frac{1}{2})=\frac{1}{5}

Of all the students, \frac{1}{5} are boys without brown hair.

Which order pair is a solution to the system of linear equations -4+y=8 and x-5y=17?
andreev551 [17]

Hello!

To find this ordered pair, we solve for x and y and put them together in an ordered pair.

-4+y=8

x-5y=17

Let's solve the first equation for y.

y= 12

Now, let's plug 12 into the second equation for y.

x-5(12)=17

x-60=17

x=77

Therefore, our ordered pair is (77,12)

I hope this helps!
