svlad2 [7]2 years ago
3 0

Answer:

here you go :)

Step-by-step explanation:

Replace the variables with their corresponding values:

\frac{2(5+3)}{2*5}

Cancel out 2 in both numerator and denominator.

\frac{3+5}{5}

Add 3 and 5 to get 8.

\frac{8}{5}

Finally, divide 8 by 5 to get your answer:

\frac{8}{5} = 1.6

Your answer is (a) 1.6

Find the slope of the line perpendicular to the line passing through the given points: (-4, 8) and (-2, 5)​
frozen [14]

Answer:

\frac{3}{2}

Step-by-step explanation

  The slope of a perpendicular line would be (-x) if the slope of the original line was (x).

  The formula for finding slope is:

\frac{y_2-y_1}{x_2-x_1}

Inserting your problem would make the equation look like:

\frac{5-8}{-2+4}

Simplify:

\frac{-3}{2}

That is the slope of the given line, to find the slope of the line perpendicular to that one, we would put into (-x)

Answer:

\frac{3}{2}

The sum of three numbers is 20. The second number is 4 times the first, and the sum of the first and the third is 8. Find the nu
Digiron [165]

Answer:

The numbers are 3, 12 and 5.

Step-by-step explanation:

Let the numbers =x, y and z.

The sum of three numbers is 20 implies x+y+z=20----------------i

The second number is 4 times the first implies y=4x--------------ii

The sum of the first and the third is 8 means x+z=8---------------iii

from (i), z=20-x-y---------iv

Put (iv) in (iii),

x+20-x-y=8

20-y=8

y=20-8=12

y=12

Put y=12 in (ii)

4x=y

x=y/4 = 12/4 = 3

x=3

Put x=3 and y=12 in (iv)

z=20-3-12=5

z=5

Therefore, the numbers are 3, 12 and 5.
