If 5a = 25 and 5b = 625 what is 5b-a?

1 answer:

6 0

Think about the individual parts of the expression.

5b - a

5b equals 625. Therefore, 5b - a = 625 - a

Now you have 625 - a.

If 5a = 25, then what does "a" equal? Divide 5 from both sides to find out.

5a/5 = 25/5

a = 5

Therefore, 625 - a = 625 - 5

625 - 5 = 620

620 is the answer.

I'm confused on how to find x

azamat

Answer:

x = 2

Step-by-step explanation:

Since this is a 45-45-90 triangle, the 2 legs will be the same, meaning that y will also be $\sqrt2$ .

We can then solve for x using the Pythagorean theorem:

$\sqrt2^2+\sqrt2^2=x^2\\2+2=x^2\\4=x^2\\x=2$

Or, we could use a quicker approach: if the triangle is a 45-45-90 triangle, the hypotenuse will be $\sqrt2$ times the length of 1 leg. It essentially does the same thing; it's just faster so you could save time on tests.
