Explain how to use division to find an equivalent fraction for 9/12

Answer:

3/4

Step-by-step explanation:

You can simplify it by looking for what divides into both numbers. The lowest possible number is 3 because it can go into both 9 and 12.

9/3=3

12/3=4

3/4

So we know that 3/4 is equivalent to 9/12, because 3×12=36 and 4×9=36. A simple way to look at how to check for equivalent fractions is to do what is called “cross-multiply”, which means multiple the numerator of one fraction by the denominator of the other fraction. Then do the same thing in reverse.

Answer:

Line 1: -2

Line 2: 2

Line 3: 2

Line 1 & 2 is parallel.

Line 2 & 3 is neither.

Step-by-step explanation:

To find the slope of a line use the slope formula and substitute the points into it:

Line 1

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{2--2}{0-2} =\frac{2+2}{-2} =\frac{4}{-2}=-2$

Line 2

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{-5--1}{1--1} =\frac{-5+1}{1+1} =\frac{-4}{2}= -2$

Line 3

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{0--4}{-3--5} =\frac{0+4}{-3+5} =\frac{4}{2}=2$

Parallel lines have the same slope and perpendicular lines have negative reciprocal slopes.

Line 1 & 2 is parallel.

Line 2 & 3 is neither.

Sarah inherited a sum of 1,539 dollars with an interest rate of 1% per year what is the accrued value after 5 years, 10 years, a

JulijaS [17]

Answer:

See explanation

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest,

P = principal,

r = rate (as decimal),

t = time

In your case,

$P=\$1,539\\ \\r=0.01$

If $t_1=5$ years, then

$I_1=1,539\cdot 0.01\cdot 5=76.95$ and the whole sum is $\$1,539+\$76.95=\$1,615.95$

If $t_2=10$ years, then

$I_2=1,539\cdot 0.01\cdot 10=153.9$ and the whole sum is $\$1,539+\$153.9=\$1,692.9$

If $t_3=15$ years, then

$I_3=1,539\cdot 0.01\cdot 15=230.85$ and the whole sum is $\$1,539+\$230.85=\$1,769.85$
