A girl is half as old as her sister and is also two years younger than her brother. If the sum of the three children's ages is 34 years, what is the product of their ages?
ASAP pls

Answers

Answer:

1280

Step-by-step explanation:

Let x represent the age of the girl then...

Brother: x+2

Sister: 2x

We can use this to set up an equation:

x+x+2+2x=34

Combine like terms

4x+2=34

Subtract 2 from both sides

4x=32

Divide both sides by 4

x=8 (girl)

x+2=10 (brother)

2x=16 (sister)

Now, we multiply these three numbers to get the product of their ages.

8(10)(16)=80(16)=1280

Saskia is solving an equation in one variable and gets the equivalent equation 3=3. Assuming her work is correct, what can she conclude about the original equation?

Answers

Answer:

The second option is correct. There are infinitely many solutions.

Step-by-step explanation:

Let's use the equation x + 3 = x + 3

We can simplify this two ways: x = x, or 3 = 3

We can use any value of x so that both sides are equivalent to each other.

For example:

x + 3 = x + 32 + 3 = 2 + 35 = 5

or

x + 3 = x + 3-3 + 3 = -3 + 30 = 0

As you can see, both sides of the equations are always the same with any value of x.

because if you times 0.25 (which is 25%) to 3 it is 0.75 which is 75% so it will increase by 25%.

a 5'10 man weighs 175 pounds. a 6'2 man weighs 200 pounds. do theses men have an equivalent height to weight ratio. Explain ur answer

Answers

Answer: No.

Step-by-step explanation:

5' 10 in inches is 70 inches, 6' 2 in inches is 74 inches

Therefore, the ratio of the first man is 70/175

Dividing by 35 on top and bottom we get 2/5

The ratio of the second man is 74/200

Dividing by 2 on the top and bottom we get 37/100

Since 37/100 does not equal 2/5, these men do not have an equivalent height to weight ratio.

For a science project, Mrs. William’s third grade class kept track on how many days it rained during the month of April. The chart below shows their results. What percentage represents the fraction of days it rained on April?

(It rained 12 days in April, and it did not rain for 18 days in April.)

Answers

Answer:

40%

Step-by-step explanation:

Step one:

Add together both when it rained and when it didn't

12 + 18 = 30

Step 2:

You are then going to divide the number of days it rained by the total amount of days are in April. (We got this by adding the two numbers above)

12/30

It will then give you the solution of 0.4

You are then going to move the decimal two places to the right.

This will give you 40%
