One way is to divide the numerator by the denominator. For a mixed number make the fraction improper and do the same.

How do u simplify 68/80

docker41 [41]

First, we go from small numbers. we know that both 68 and 80 are divisible by 2 which means that we can simplify the numbers dividing by 2. So it is 34/40. We know that again 2 is divisible by 34 and 40. So you divide 2 which gives 17/20. Now, no number is divisible by 17 and 20 so your answer is 17/20

Solve the linear equation. 14x − 1/2 (4x+6) = 3 (x−4) − 18

LekaFEV [45]

$14x - (2x + 3) = 3x - 12 - 18 \\ 14x - 2x - 3 = 3x - 30 \\ 12x - 3 = 3x - 30 \\ 9x = - 27 \\ x = - 3$

The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that r

Lelechka [254]

Answer:

Option A) is correct.

Step-by-step explanation:

The final cost of a sale item is determined by multiplying the price on the tag by 75%.

So. if the final cost is represented by $F and the price on the tag is $t, then the relation between F and t will be

F = 0.75t.

This relation is linear since the ratio of the change in the final cost compared to the rate of change in the price tag is constant.

Therefore, option A) is correct. (Answer)

Line segment AB has endpoints A(3, -7) and B(-9,-5). Find the equation of the perpendicular bisector

kupik [55]

Answer:

y = 6x + 12

Step-by-step explanation:

We require the midpoint M and slope of AB

Using the midpoint formula, then

M = [ $\frac{1}{2}$ (3 - 9) , $\frac{1}{2}$ (- 7 - 5) ] = (- 3, - 6 )

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = A(3, - 7) and (x₂, y₂ ) = B(- 9, - 5)

m = $\frac{-5+7}{-9-3}$ = $\frac{2}{-12}$ = - $\frac{1}{6}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{1}{6} }$ = 6

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 6 , thus

y = 6x + c ← is the partial equation

To find c substitute M(- 3, - 6) into the partial equation

- 6 = - 18 + c ⇒ c = - 6 + 18 = 12

y = 6x + 12 ← equation of perpendicular bisector
