Answer:

$\large \boxed{X = 4}$

Step-by-step explanation:

5/2.5 = X/2

To solve a proportion, use the following equation:

(numerator * opposite denominator) = (numerator * opposite denominator)

Substitute in given numbers

(5 * 2) = (X * 2.5)

Multiply to simplify

10 = 2.5X

Divide both sides of this equation by 2.5

$\large \boxed{X = 4}$

Hope this helps :)

How is the Distributive Property used to simplify operations with scientific notation

Citrus2011 [14]

Answer:

See explanation

Step-by-step explanation:

Let a,b, and c be real numbers.

The distributive property says that:

$a(b + c) = ab + ac$

Assuming we want to simplify:

$10(5*10^{-1}+150*10^{-3})$

We apply the distributive property to get:

$10(5*10^{-1}+150*10^{-3}) = 5*10^{-1} \times 10+150*10^{-3} \times 10$

We can now use rules of exponents to simplify further:

$10(5*10^{-1}+150*10^{-3}) = 5*10^{-1} \times 10^{1} +150*10^{-3} \times 10^{1}$

$10(5*10^{-1}+150*10^{-3}) = 5*10^{-1 + 1} +150*10^{-3 + 1}$

$10(5*10^{-1}+150*10^{-3}) = 5*10^{0} +150*10^{-2}$

$10(5*10^{-1}+150*10^{-3}) = 5*1+1.50*10^{-2}x {10}^{2}$

$10(5*10^{-1}+150*10^{-3}) = 5*1+1.50*10^{-2 + 2}$

$10(5*10^{-1}+150*10^{-3}) = 5+1.50*10^{0} = 6.5 \times {10}^{0}$

dolphi86 [110]

Answer:

The answer is the square root of 8, or 2root2.

Step-by-step explanation:

Use the distance formula.

d = sqrt((-3-(-5))^2 + (-3-(-1)))

d = sqrt(2^2 + 2^2)

d = sqrt(4 + 4)

d = sqrt8

d = sqrt4 * sqrt2

d = 2 * sqrt2

PLEASE HELP!!!! WHOEVER ANSWERS FIRST WILL BE MARKED BRAINLIEST!!!

Yakvenalex [24]

Answer:

The answer is A.

Step-by-step explanation:

All you have to do is find the slope, which is given in the question and then count it and see what line goes with the slope you were given.

1/3 is the slope so count that to check your work, and it works out :)
