Find the value of x in the equation below 5= x/6

Answers

Answer:

x=30

Step-by-step explanation:

Answer:

x=30

Step-by-step explanation:

To find the value of x in an equation, our goal is always to isolate it so that it's on one side of the equal sign while everything else is on the other. We can do this by performing inverse operations to cancel values out (for example, the inverse operation of addition is subtraction and the inverse operation of division is multiplication).

5=x/6

Because x is being divided by 6, we multiply both sides by 6 to cancel it out on the side with x.

5×6=(x/6)×6

5×6=x

30=x

DOGS During a recent visit to the veterinarian's office, Mrs. Cho was informed that a healthy weight for her cat is approximately 35 pounds, plus or minus three pounds. Write an absolute value inequality that represents healthy weights w for her dog.

Answers

Answer:

Step-by-step explanation:

from the given information:

The healthy weight of the cat = 35 pounds

with +/- 3

To write the absolute value;

The healthy weight will either be less or greater.

So; w > 35 +3  or    w < 35 - 3

w - 35 > 3        or     w - 35 < -3

Thus, the healthy weight will be |w - 35| > 3

Step-by-step explanation:

y in (-oo:+oo)

(1/3)*y = 15 // - 15

(1/3)*y-15 = 0

1/3*y-15 = 0 // + 15

1/3*y = 15 // : 1/3

y = 15/1/3

y = 45

y = 45

What are the zeros of the polynomial function? State the multiplicity of each zero y=(x+2)(x-3)^2

Answers

Answ er:

-2,  3

Step-b y-step explanation:

The question is asking what x equals that makes y equals 0

How do we do this?

Because we're multiplying things together we just need one part of the equation to equal 0

for example if x= -2 then we would have the following

(-2+2)(-2-3)^2

(0)(-5)^2

which is 0

and the other answer is 3 because when you have

x-3=0

x= 3
