Answer:
Since it is a right angle, you know that the angle measures 90 degrees. Since one acute angle measures 5x (times) the other, you would set it up in equation format as 5x + x = 90.
5x + x = 6x, so
6x = 90
you divide both both sides by 6 (90/6) = 15
To find the measure of the angle that is 5x (times) the other, you do 5(15) = 75 degrees and the other angle is 15 degrees, which adds up to 90 degrees.
Mark me brainiest
x - 3(2x - 7) = 76
x - 3(2x) - 3(-7) = 76
x - 6x + 21 = 76
-5x + 21 = 76
<u> - 21 - 21</u>
<u>-5x</u> = <u>55</u>
-5 -5
x = -11

You will pay $360 for a item with original price of $450 when discounted 20%. 450x0.2=90.00 then 450-90=360
final speed of the 3.0 kg cart is 2.67 m/s .
<u>Step-by-step explanation:</u>
Here we have , A 2.0 kg cart moving right at 5.0 on a friction less track collides with a 3.0 kg cart initially at rest. The 2.0 kg cart has a final speed of 1.0 to the left. We will use law of conservation of momentum: For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, final speed of the 3.0 kg cart is 2.67 m/s .
