18:30 as a ratio simplified, please :))

1 answer:

6 0

The answer is 3:5

to find it, divide both sides of 18:30 by the GCF
the GCF of 18 and 30 is 6
so, 18/6=3 and 30/6=5

the simplified ratio is 3:5

Two more than the quotient of a number and 5 is 8.<br><br> use variable w for the unknown number.

KengaRu [80]

Answer:

The answer is that w = 30

Step-by-step explanation:

To find this, we start by modeling the equation.

w/5 + 2 = 8

We know it looks like this since they say quotient, which means division problem.

w/5 + 2 = 8

w/5 = 6

w = 30

What is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?

zhenek [66]

First we have to find the slope of the givent line and for that we use rise / run method .

The points are (-4,4),(4,-2)

Here rise is

$-2-4 =-6$

And run is

$4-(-4)=8$

So slope is

$= \frac{-6}{8} = \frac{-3}{4}$

And the slopes of perpendicular lines are negative reciprocal of each other .

Therefore the slope of the required perpendicular line is

$-(- \frac{4}{3}) = \frac{4}{3}$

Now we use slope intercept form, and put x intercept , that is (6,0) and the slope that is 4/3 ,

$y=mx+b
\\
0 = \frac{4}{3}*6 +b
\\
0=8+b
\\
b =-8$

Therefore required equation is

$y= \frac{4}{3}x -8$

Correct option is the third option .

M= -5, point: (7.1.–6.5)<br> Equation of line

OleMash [197]

Answer:

y + 6.5 =-5 (x - 7.1)

Step-by-step explanation:

We can use the point slope equation of a line

y -y1 = m(x-x1)

We have a point and a slope

y - - 6.5 = -5 (x - 7.1)

y + 6.5 =-5 (x - 7.1)
