Answer:

7/10 or 0.7

Step-by-step explanation:

cross multiply to get 40x+20=48

subtract 20 from both sides to get 40x=28

divide both sides by 40 to get 7/10

Answer:

0.7 or 7/10

Step-by-step explanation:

Step 1: Cross-multiply.

2x+1 / 4 = 12 /20

(2x+1)*(20)=(12)*(4)

40x+20=48

Step 2: Subtract 20 from both sides.

40x+20−20=48−20

40x=28

Step 3: Divide both sides by 40.

40x /40 = 28 /40

x= 7 /10

Answer:

x= 7 /10

7/10 = 0.7

Answer:

43.13

Step-by-step explanation:

We can tell that the right corner of the triangle is 90 degrees.

The sum of the degrees inside of a triangle is 180

so 90 + 27 = 117

180 - 117 = 63

so we get out angles

27,90,63

Next we can use the law of sines to find the height.

Law of sines: side/sin(opposite angle)= side/sin(opposite angle)

So we get the opposite angle of the side given which would be 90

And we get the ratio: 95/sin(90) = x/sin(27)

We solve for x and get 43.1

write an equation in point-point form for the line through the given point with the givedescribe how the graph of y | x| -4 is l

Digiron [165]

a) The point-slope form of the equation of a line through point (h, k) with slope m is
y - k = m(x - h)

In point-slope form, the equation of the line through (-3, -7) with slope -6/5 is
y + 7 = (-6/5)(x + 3)

b) The graph of
y = |x|-4
represents a translation downward 4 units of the graph of
y = |x|
It retains the same general shape and axis of symmetry, but will have two (2) x-intercepts instead of one (1).
