Answer:
Mark has 6 times as many as Tom
Step-by-step explanation:
Elijah = E
Tom = T
Mark = M
Translate the information into mathematical equation :
E = 3T
M = 2E
How many times Mark has as many as Tom ?
M = ..... T ?
M = 2 E (Remember, E = 3T, insert this)
M = 2 ( 3 T )
M = 6 T
Mark has 6 times as many as Tom
An isosceles triangle has two congruent sides and angles
The value of x in the isosceles triangle is
<h3>How to determine the value of x</h3>
To calculate the value of x, we make use of the following Pythagoras theorem
![x = \sqrt{4^2 + (6/2)^2](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B4%5E2%20%2B%20%286%2F2%29%5E2)
So, we have:
![x = \sqrt{4^2 + 3^2](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B4%5E2%20%2B%203%5E2)
Evaluate the squares
![x = \sqrt{16 + 9](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B16%20%2B%209)
![x = \sqrt{25](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B25)
Evaluate the exponent
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Hence, the value of x is 5
