Answer:

<h3>N=-4</h3>

Step-by-step explanation:

Isolate n on one side of the equation.

<em><u>DISTRIBUTIVE PROPERTY:</u></em>

A(B+C)=AB+AC

A(B-C)=AB-AC

6(8+5n) (First, expand by using distributive property.)

6*8=48

6*5n=30n

48+30n

8n-40=48+30n

8n-40+40=48+30n+40 (Next, add 40 from both sides.)

48+40 (Solve.)

48+40=88

8n=30n+88

8n-30n=30n+88-30n (Subtract 30 from both sides.)

8n-30n (Solve.)

8n-30n=-22n

-22n=88

-22n/-22=88/-22 (Then, divide by -22 from both sides.)

88/-22 (Solve.)

88/-22=-4

n=-4

Therefore, the final answer is n=-4.

The total number of cats and dogs at the shelteris 125. there are 5 more cats than dogs
juin [17]
If you're looking for the number of dogs (I'm assuming, you didn't specify), all you'd have to do is divide the number by two, then round down to find the number of dogs, then check your answer by adding that number and that number plus 5.

For example, yours would look like 125/6=62.5, and rounding down to 60.

Then check your answer by adding 60 and 65, the number of cats. 60+65=125.

There are 60 dogs inside the kennel.

Find the solution for y=2x-1 y=3x+2
ziro4ka [17]
ANSWER: (-3,-7)
Set them equal to each other so, 2x-1=3x+2 to find x. You should get x= -3


Then you plug in -3 for x to find Y for either y=2x-1 or y=3x+2. I’m picking y=3x+2 so when you plug in -3 to x it will be y=3(-3)+2 = -7 . So therefore y=-7
