<em>Let the expression = x</em>

<em>x = [ ( 2 X 7 ) + 2] / 7   -   [ ( 1 X 3 ) + 1 ] / 3</em>
<em>  = [ 14 + 2 ] / 7   -   [ 3 + 1 ] / 3</em>
<em>  = 16 / 7    -   4 / 3</em>
<em>  = ( 48 - 28 ) / 21</em>
<em><u>  = 20 / 21 Answer.. :)</u></em>

2\frac{2}{7}-1\frac{1}{3}=2\frac{6}{21}-1\frac{7}{21}=1\frac{21+6}{21}-1\frac{7}{21}=1\frac{27}{21}-1\frac{7}{21}=\boxed{\frac{20}{21}}

Find x and fill in the angle values. Could you also explain how it works? Please and thank you.

Hello!

Angles 3 and 1 are vertical angles, and angles 2 and 4 are vertical angles. Vertical angles are congruent by definition, so angle 3 is congruent to angle 1, and angle 2 is congruent to angle 4.

The adjacent angles are supplementary (they add to equal 180 degrees) so you can set up an equation to solve for x.

180 = 2x + x
180 = 3x
60 = x

x = 60

To find the measure if each angle, plug in x as needed.

Angle 4 = x
Angle 4 = 60 degrees

Angle 2 = angle 4
Angle 2 = 60 degrees

Angle 3 = 2x
Angle 3 = 2(60)
Angle 3 = 120

Angle 1 = angle 3
Angle 1 = 120

I hope this helps you.

I got number 7 wrong can someone help me with the answer and the work
Amiraneli [1.4K]
To figure out this problem break it down into steps.

We know that there are 1 - 25 or 25 cards in total, one card is taken out and not replaced so now there are only 24 cards.

25 - 1 = 24.

Find the probability of getting one number greater than 10, this would be all numbers from 10 - 25, which are 25 - 10 = 15 options to choose that will give you a value greater than 10.

Probability = 15/24 = 5/8.

For 2 cards simply multiply the probability by itself to get 2 cards where the number is greater than 10.

5/8 • 5/8 = 25/64.

The probability of getting 2 cards that are greater than 10, are 25/64.

This is the solution.
