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

Hester sells televisions. she earns a fixed amount for each television and an additional $30 if the buyer gets an extended warranty. If Hester sells 13 televisions with extended​ warranties, she earns 13,00. How much is the fixed amount earns for each​ television?

Answers

Using proportions, it is found that the fixed amount that she earns for each television is of $70.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, she sold 13 televisions with warranty, hence earning a total in bonus of 13 x $30 = $390.

Hence, the sum of the 13 fixed amounts is of 1300 - 390 = 910, hence the fixed amount she earns is given by:

$910/13 = 70.

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

pls help i will give the brinlist:0

Step-by-step explanation:

let jon age be x

dad age is 2 of x i.e 2x

grandpa age is 7 + 3(x)

The sum of jon dad and grandpa age is 145 i.e

x + 2x + (7+3x) = 145

3x +. 7 + 3x = 145

6x = 145- 7

6x = 138

divide both sides by 6

x = 23

jon age is 23

while
