Answer:
480 Boy
Step-by-step explanation:
The ratio of Boys = 4x
The ratio of Girls = 5x
The Number of Boys in the School = 4x + 5x = 1080
= 9x = 1080
= x = 1080/9
= x = 120
The ratio of Boys = 4x = 4 x 120 = 480
The ratio of Girls = 5x = 5 x 120 = 600
Hence, Number of Boys = 480
Ratio Boys to Girls = 480:600

Use the formula slope= y-y/x-x
-10-r/-2-8= 1/10
-10-r/-10= 1/10
Multiply the denominator (-10) on both sides
-10-r= -1
Add -10 to both sides
-r= 9
r= -9
Hope this helps!

Answer:
<em>The length and width of the deck will be 11 meters and 9 meters respectively. </em>
Step-by-step explanation:
The length of the rectangular deck is meter and width is meter.
The perimeter of the deck should be 40 meters. So, the first equation will be...
The difference between twice the length and twice the width should be 4 meters. So, the second equation will be....
<u>Adding equation (1) and (2)</u>, we will get.....
<u>Now plugging this into equation (1)</u>, we will get....
So, the length and width of the deck will be 11 meters and 9 meters respectively.
