You should divide 48,000 by 12 which is 4000+ 2000=6000
So it should be $6000
Hope this is right I’m not 100%

Ok, so they are all balanced, so each side of the scale thing is equal to the other side.

A. 3 + x = 8
If we subtract 3 from 8, what’s left is 5 for x
x = 5

B. 2y = 12
Both y weights are equal, so dividing 12 by 2 says each y weight is 6.
y = 6

C. 4z = 11
All z weights are equal, so divide 11 by 4 to find the weight of z
z = 2.75

D. 3 4/5 + w = 13 4/5

Subtract 3 4/5 from 13 4/5 to find the weight of w
w = 10

Let me know if you have questions about this.

The number of basketball games that must be scheduled in a league with n teams is given by G(n) = (n2 - n)/2 where each team pla

Pani-rosa [81]

Answer:

There are 7 teams in the league

Step-by-step explanation:

Given that the number of games is given by:

$G(n) = \frac{(n^2-n)}{2}$

The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21

Putting this mathematically

$21 = \frac{n^2-n}{2}$

Multiplying equation by 2

$2*21 = 2*\frac{n^2-n}{2}\\42 = n^2-n\\n^2-n-42 = 0\\n^2-7n+6n-42 = 0\\n(n-7)+6(n-7) = 0\\(n-7)(n+6)=0\\n-7 = 0 => n=7\\n+6=0 => n=-6$

As the number of teams cannot be negative, the number of teams in league are 7.

Hence,

There are 7 teams in the league

What is the answer to 3 + y; 1/3 (6+y)

baherus [9]

Answer:

No, the expression are not equivalent.

Step-by-step explanation:

No way to simplify 3 + y so we leave it as is. Let's look at $\frac{1}{3}\left(6+y\right)$

If we expand using distributive property we get:

$2+\frac{y}{3}$

3 + y does not equal to 2 + y/3.

In ΔKLM, the measure of ∠M=90°, the measure of ∠K=85°, and MK = 6.9 feet. Find the length of KL to the nearest tenth of a foot.

liq [111]

First take 180-90-85=5 for L angle then we can take tan(85)=ML/6.9, 6.9(tan(85))=ML. So ML=78.87ft. Now we can use Pythagorean theorem to find our KL so KL = sqrt((78.87)^2+(6.9)^2) and we get our answer KL=79.17ft. Hope it helps
