Answer:

If we assume that everyone in the group is an owner, we would have

20*2=40 legs.

64-40=24 legs

Therefore, we need 24 more legs.

These 24 additional legs can be made from the difference of legs between the owners and dogs.

In this case, dogs have 4-2=2 more legs than an owner.

24 ÷ 2 = 12.

There are 12 dogs in the group.

Suppose that Sahil knows that 45 people with the ages of 18 to 19 voted. With out using a calculator, he quickly says then 135 p
Amiraneli [1.4K]
So you are given that 45 people in the age range of 18 to 29 who voted make up 10% of the total voters.

And you also know that 30% of the voters are in the age range of 30-49. And you need to find out how many people aged 30-49 voted.

So 10% of the total make up 45 people.
That means for 30% of the total number people, there would be 45 x 3 people, or 135 people. Because 10% x 3 = 30%

So, great job! :D

Show that x+y:x-y=3:2
ycow [4]

We have,

x+y:x-y=3:2

To prove that, x+ y : x - y = 3:2.

x+y=3  

And,

x+y = 2      

Adding (1) and (2), we get

x+y+x-y=3+2

⇒2x=5

⇒ x =

Put x =  in (1), we get

+y=3

⇒ y=3-=

x+y:x-y=

=3:2

So, x+y:x-y=3:2.

Identify the slope by converting standard form into slope-intercept form.<br> 12x - 9y = -9
Novosadov [1.4K]

Answer:

4/3

Step-by-step explanation:

12x-9y=-9

9y=12x-(-9)

9y=12x+9

y=12/9x+9/9

y=4/3x+1

y=mx+b where m=slope and b=y-intercept,

so the slope is 4/3
