50% of a certain number is 39. What is the number?
Allushta [10]
Let that certain number be 'n'

50% (n) = 39

50% ⇒ 0.5

0.5 (n) = 39

Divide both sides by 0.5

0.5n = 39
 /0.5    /0.5

n = 78.

So that certain number is actually <em><u>78! :)</u></em>

CROSS CHECK:

50% of 78

0.5 × 78

= 39

Hope this helps! :)

10^x • 100^2x = 1000^5. Step by Step
nordsb [41]
Step one: set the base of each term to be the same (10)
(10ˣ)(10²)²ˣ = (10³)⁵
(10ˣ) (10⁴ˣ)= (10¹⁵)
10⁵ˣ = 10¹⁵
Because the indices are the same we can equate the two.
5x = 15
x = 3

Check 10⁵ˣ³ = 10¹⁵    10¹⁵=10¹⁵
