The correct answer is A. x=22
Since the angles of a rectangle are right angles (90 degrees) you would set it up as 90=5x-20. Then combine like terms and solve the equation. (If you need me to show you how step by step tell me)
162 is not a perfect square therefore you have to find the largest perfect square that can go into 162 which would be 81.
7/10 of 80 is 56
4/5 of 80 is 64
3/4 of 80 is 60
5/8 of 80 is 50
1/2 of 80 is 40
1/4 of 80 is 20
1/10 of 80 is 8
1/8 of 80 is 10
to work these out divide the number by the denominator (bottom number) and multiply by the numerator (top number)
The answer is 32, because when you divide by a fraction you have to multiply the number by it's reciprocal.
Which statements are true about the ordered pair <span>(−1, 5)</span> and the system of equations?
<span>{<span><span>x+y=4 </span><span>x−y=−6</span></span></span>
Select each correct answer.
<span>The ordered pair <span>(−1, 5)</span> is a solution to the first equation because it makes the first equation true.The ordered pair <span>(−1, 5)</span> is a solution to the second equation because it makes the second equation true.The ordered pair <span>(−1, 5)</span> is not a solution to the system because it makes at least one of the equations false.The ordered pair <span>(−1, 5)</span> is a solution to the system because it makes both </span>
