Answer:

Step-by-step explanation:

When solving proportions like these, you can set them up using fractions

#1:

\frac{3}{9} = \frac{2}{x}\\\frac{1}{3} = \frac{2}{x}\\cross \: multiply\\x = 6\\3:9 = 2:6

#2:

\frac{57}{x} = \frac{19}{38}\\\frac{57}{x} = \frac{1}{2}   \\x = 114\\57 : 114 = 19 : 38

#3:

\frac{7}{x} = \frac{2}{3}  \\21 = 2x\\x = \frac{21}{2} = 10.5\\7:10.5 = 2:3

#4

\frac{15}{2} = \frac{x}{8}\\x = \frac{15*8}{2} = 60\\15:2 = 60:8

#5

\frac{0.3}{4} = \frac{9}{x}\\0.3x = 36\\x = \frac{36}{0.3} = 120  \\0.3:4 = 9:120

Answer: 10%, 0.5, 3/4


Step-by-step explanation:

What you want to do is convert them all to one unit. The eaisest would be a decimal.

Starting off with .5, it's already in decimal form.

Next go to 10%. 10% as a decimal will be 0.1, because its 1/10.

Lastly, go to 3/4. 3/5 as a decimal would be 0.75.

Putting them in order from least to greatest would be 10%, 0.5, 3/4.

(Hope that helps)

How do you write an equation of a line in standard form if you have two points?
ziro4ka [17]
First find the slope using the slope formula M= (y2-y1) divided by (x2-x1) and then take the slope and and the 1st set of points (x1, y1) and plug it into the slope intercept formula which is y-y1=m(x-x1), then you need to add or subtract variables to correlate with the standard form formula which is ax + by = c.
Hope that helps!
