Answer:
8.5% (you can approximate that, that's the exact number and it isn't too funky)
Step-by-step explanation:
Percentage is out of 100, and over here we see that 200 is 2 times the amount of 100. So that means that if we divide 200 by 2, we get 100, which means we also divide 19/2 to get 8.5. That means, out of 100 light bulbs, 8.5 of them burned out. This is really easy to convert because the percentage is already out of 100, so you just make 8.5 into a percent which is 8.5%
Let me know if you have any questions.
-4.5x + 40.05 = 12.6
-4.5x = -27.45
x = 6.1
- Given - <u>the </u><u>difference</u><u> </u><u>between </u><u>two </u><u>numbers </u><u>is </u><u>9</u><u> </u><u>and </u><u>the </u><u>numbers </u><u>are </u><u>in </u><u>the </u><u>ratio</u><u> </u><u>of </u><u>4</u><u>:</u><u>7</u>
- To find - <u>the </u><u>numbers</u>
Let the number be 4x and 7x respectively !
Then ,
therefore ,
<u>first </u><u>number</u> = 4x = 4 × 3 = <u>1</u><u>2</u>
<u>second</u><u> </u><u>number</u> = 7x = 7 × 3 = <u>2</u><u>1</u>

1. solve for X and y using both equations to find the point they cross in
−x − y = −5
y = x + 1
Plug in y into first equation
-x-(x+1)=-5
-x-x-1=-5
-2x-1=-5
+1 both sides
-2x=-4
÷-2 both sides
x=2 solve for y
y=2+1
y=3
(2,3)
2. you can set them equal to each other so 2x+4=3x+1
