Brandon is 25 and Keven is 18.
To find this answer, you must first subtract 7 from 43. This will give you 36. By doing this, you're taking away that 7 year difference temporarily.
Next, divide 36 by 2, since there are 2 people. This gives you 18, which is how old Keven is.
Lastly, add 7 to 18, giving you 25. Thus meaning Brandon is 25.
I hope this helps!

a number that can written as 40 + 5 will be 45
Step-by-step explanation:
a) 24.7×52.3=1291.81
On rounding off to 3 significant digits we get
1290
b)
=31.304951
On rounding off to 5 significant figures we get
=31.305
c)
![\sqrt[3]{78} = 4.27265](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B78%7D%20%20%3D%204.27265)
On rounding off to 2 significant figures we get
=4.3
Hence required answers
a)1290
b)31.305
