It would be 19/6 as an improper fraction and 3 & 1/6 as a mixed number fraction.
Hello! I would love to help!
Let's first define solve. Solve means to get the variable, or unknown, by itself. So, we know that we've solved the equation if we get our variable, x, by itself.
Let's look at the problem like this: What number, minus 1/2, is equal to 4?
To solve this problem, let's reverse the order.
X-1/2=4
Since it is -1/2, let's add 1/2 to each side to cancel the one half out, since -1/2+1/2=0
X-1/2+1/2=4+1/2
Now, we can simplify!
X=4 1/2
That is your answer! X=4 1/2 or as an improper fraction 9/2.

Answer:
32cm and 28cm
Step-by-step explanation:
Area of a trapezium=0.5 ( sum of parallel sides ) × height
600=0.5( 4+a+a)×20
where a is the length of the shorter side
600÷0.5=(4+2a)×20
1200=(4+2a)×20
1200÷20=4+2a
60=4+2a
60-4=2a
56=2a
56÷2=a
28=a.
since the longer side is 4 cm more than th shorter side , 28 +4=32
