Answer:

y = 4 / x = 2

Step-by-step explanation:

Insert x equation for variable x

y = 2(-y+6)

simplify

y= -2y + 12

add 2y to both sides

3y= 12

divide both sides by 3

y = 4

Insert 4 as y in y =2x

4=2x

divide both sides by 2

x=2

Find the difference. Enter your answer in lowest terms in the box below as a

lara [203]

Answer:

76/165

Step-by-step explanation:

The difference of fractions can be found using the formula ...

a/b -c/d = (ad -bc)/(bd)

<h3>Difference</h3>

Using the given values in the formula, we have ...

$\dfrac{8}{11}-\dfrac{4}{15}=\dfrac{8(15)-11(4)}{11\cdot15}=\dfrac{120-44}{165}=\boxed{\dfrac{76}{165}}$

Here, the difference fraction does not need to be reduced. Many calculators and spreadsheets can do this arithmetic for you.

The above formula can also be used for sums of fractions. In that case, the sign changes from minus to plus.

saveliy_v [14]

Answer:

12h < 60

Step-by-step explanation:

A rectangle, with height h and base length l, has the following area.

$A = l*h$

In this question:

$l = 12, A < 60$

$A < 60$

$l*h < 60$

$12h < 60$

So the correct answer is:

12h < 60

Bill needs to edge his yard with the dimensions in the shape below. What distance will he have walked after completing his edgin

Montano1993 [528]

Answer:

37.8 m

Step-by-step explanation:

The computation of the distance is shown below:

In triangle ADE

$AD^2 = AE^2 + DE^2 \\\\ AD^2 = 5^2 + 3^2 \\\\ AD^2 = 34$

AD = 5.8

Now the distance walked after completing his edging is

Distance = AD + AB + BC + CD

= 5.8 + 12 + 5 + 15

= 37.8 m

We simply added these four sides so that the correct distance could arrive

Hence, the distance walked after completing his edging is 37.7
