All the prime numbers betwemn 20 and 30 are 23 and 29
50%, if you put it into a calculator 25/50 gives you .50, move decimal 2 times to the right to get 50.

True about area II and III
The question is incomplete; so, I will answer using general knowledge.
If the total area is:
And there are 4 areas, then;
Rewrite as:
This gives:
Collect like terms
Rewrite as:
<em>So, the sum of areas III and IV must be 14x</em>
Answer: √51
—————————
a^2 + b^2 = c^2
a^2 + 7^2 = 10^2
a^2 + 49 = 100
a^2 = 51
√(a^2) = √51
a = √51
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
