When 40% is added, it becomes 140%
140% = 182
1% = 182 ÷ 140 = 1.3
100% = 1.3 x 100 =130
The number is 130
C) I and III only
THird one is true and it is only option containing the third option
Answer:
The answer is x = 9
We use Pythagoras theorem to form the equation and solve for x
That's
a² = b² + c²
where a is the hypotenuse
we get
(x + 6)² = 12² + x²
Expand
x² + 12x + 36 = 144 + x²
Group like terms
We have
x² - x ² + 12x = 144 - 36
12x = 108
Divide both sides by 9
That's
12x/12 = 108/12
x = 9
Hope this helps you.

________________________________________Given:
2/ (7x) = 6/5;
→ (6/5) * (7x) = 2 ;
42x / 5 = 2 ;
42x = 2*5 ;
42x = 10 ;
42x /42 = 10/42 ;
x = 10/42 = (10÷2) / (42÷2) = 5/21 ;
x =
;
→ which is:
Answer choice: [A]: "

Answer:
30
Explanation:
24^2+18^2
=900
√900
=30
(You have to use Pythagorean theorem so a^2+b^2=c^2)
