Step-by-step explanation:

multiply 455 by 0.20

convert percentage to decimal

20% = 0.20 ( multiply by 10^-2)

why does this work?

convert to a fraction

20/100 ( this is also how you get decimal)

simplify 20/100 = 1/5

so multiplying 455 by 0.20 is the same as dividing by 5

3/4 = c/36<br><br><br> I need help with this fraction proble.
Nataliya [291]

Answer:

c = 27

Step-by-step explanation:

given \frac{3}{4} = \frac{c}{36} ( cross- multiply )

4c = 3 × 36 = 108 ( divide both sides by 4 )

c = 27

note that \frac{27}{36} = \frac{3}{4} in simplest form

Graph the line through point (1,1) with slope 2.
Luba_88 [7]

Step-by-step explanation:

The equation of a line is y=mx+b, where m is the slope and b is the y intercept.

We know that the line pass through the point (1,1) and the slope is 2.

m=2

Then,

y=2x+b

We have to find b.

If we replace the point (1,1) in y=2x+b we will obtain b.

Then,

y=2x+b\\1=2.1+b\\1=2+b\\1-2=b\\-1=b

y=2x-1

The y intercept then is -1, this means that when x=0, y=-1.

We have the point (0,-1).

Now to obtain another point we have to replace  y=2x-1 with y=0.

y=2x-1\\0=2x-1\\1=2x\\\frac{1}{2}=x

We have the point (\frac{1}{2},0)=(0.5,0)

Now that we have to points, we have to place them in the cartesian coordinate system. And then draw the line.
