Answer:1600

Step-by-step explanation:To solve this problem, we’ll have 3 variables

T for weight of tail

H for weight of head

B for weight of body

We know that T = 200 pounds

The head of the shark is the weight of the tail + half the body. Therefore, we can use the formula:

H = T + 0.5B

The body weighs as much as the head and tail. That will be

B = H + T

We can substitute H + T in the place of B in the H equation, so we get

H = T + 0.5H + 0.5T

Combining like terms, we get: 0.5H = 1.5T

Because T = 200 pounds, we can say 0.5H = 1.5 * 200, which simplifies to 0.5H = 300

Divide both sides by 0.5 and get H = 600 pounds

We can then find the weight of the body to be H + T, which is 200 + 600, and that adds up to 800 pounds

The total weight of the body is B + H + T, which equals 200 + 600 + 800, which is 1600 pounds.

Answer: Lets denote:

Tail by T

Head by H

and Body by B

Given info:

Statement 1: Head weighs as much as the tail plus half of it’s body

H =T + 1/2B

Thus,

H = 200 + 1/2 B …. Equation 1

Statement 2: Body weighs as much as head and tail.

B = H + T

B = H + 200 …. Equation 2

substituting value of B from equation 2 into 1.

H = 200 + 1/2H + 100

1/2H = 300

H = 600

B = 800

Shark’s weight = (H+T+ B) = 1600 pounds

3x-13=74 solve for x
never [62]

Answer:

x=29

Step-by-step explanation:

3x-13=74

We want to solve for x, so we need to isolate it.

The first step is to add 13 to each side.

3x-13+13=74+13

3x = 87

Then we divide by 3 on each side

3x/3 = 87/3

x= 29

Can someone please help me

For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.
