Answer: X = kuv/ (u+v)

that means that x(u+v)/(uv) = k, a constant. so you want x such that,

Is (1, 6) a solution to this system of equations? 5x + 2y = 17 x + 3y = 19 yes no

Ulleksa [173]

Answer:
Yes

Explanation:
5x + 2y = 17

We are given the values (1, 6)

Substitute then into the equation

(I put a question mark to basically ask the question “is 5(1) + 2(6) equal to 17?”)

5(1) + 2(6) = 17?
5 + 12 = 17?
Yes!

Hope this helped and made sense :)

What is the quotient written in scientific notation? 6 x 10^24 /8 x 10^8

Artist 52 [7]

When you divide 6x10^24 by 8x10^8 you end up with $\frac{6}{8} x10^{16}$

This simplifies to $0.75x10^{16}$

Now this number is not written in scientific notation as it does not have its first digit before the decimal, so we must move the decimal of this one to the right.

To do that you must multiply the number by 10.

This means that the exponet of 10 must decrease by 1.

This makes the answer $7.5x10^{15}$
