Answer:

Nicole is now 15 years old

Christine is now 5 years old

Step-by-step explanation:

x = age Nicole

y = age Christine

x = 3y

x+5 = 2×(y+5) = 2y + 10

3y + 5 = 2y + 10

y + 5 = 10

y = 5

x = 3y = 3×5 = 15

Find x<br> 25<br> 7<br> х<br> I need help

Murljashka [212]

Answer:

24 = x

Step-by-step explanation:

You use Pythagorean theorem. Since the normal equation is $a^{2} + b^{2} =c^{2}$ , you already have the $c^{2}$ and another side which can be $a^{2}$ or $b^{2}$ .

Because you have the hypotenuse and a side , your equation looks like this now: $7^{2} +b^{2} = 25^{2}$

and when you solve for be you just subtract $25^{2} -7^{2}$ to get 24.
