Consider the figure. Determine the value of y.​

Answer:

Step-by-step explanation:

Let's say I = amount of water Idalie drank,

A = amount of water Adamaris drank

J = amount of water Jonathan drank.

We are told Idalie drank twice as much water as Adamaris. You can write it as:

Idalie = 2 times Adamaris

I = 2A

Then we are told Jonathan drank 100ml more than Idalie. So

Jonathan = 100 + Idalie

J = 100 + I  (and we know I = 2A)

J = 100 + 2A

Between them they drank 3 liters (3L = 3000ml) of water.

Idalie + Adalie + Jonathan = 3000

I + A + J = 300

So since we know I = 2A and J = 100 + 2A, we can put it into the equation above:

2A + A + 100 + 2A = 3000

Gather the like terms and you get:

5A + 100 = 3000

Subtract 100 from both sides.

5A = 3000 - 100 = 2900

To find A, divide both sides by 5

A = 2900/5 = 580

This means Adamaris drank 580ml of water

The value of his hiking speed in miles per hour will be;

⇒ Speed = 9/16 miles per hour

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jerome hiked 3/4 of a mile in 2/3 of an hour.

Now,

Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.

Hence, We can formulate;

⇒ Speed = Distance / Time

⇒ Speed = 3/4 / 2/3

⇒ Speed = 3×3 / 4×4

⇒ Speed = 9/16 miles per hour

Thus, The value of his hiking speed in miles per hour will be;

⇒ Speed = 9/16 miles per hour

Answer:

4 (x + 7) = 8

Step-by-step explanation:

4 (x + 7) = 8 Because you add 7 to Amy's number  then multiplied by 4 which equals 8

Answer:

A

Step-by-step explanation:

Because the 10 is bigger then the 4 so when you do the math (y) will equal the answer of A which its  14

Answer:

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

[tex]p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...[/tex]

We have the final answer as

Answer:

  $3.50

Step-by-step explanation:

If c represents the cost of one comic book, the transaction can be written as the equation ...

  6c = $21

Dividing by 6, we get ...

  c = $21/6 = $3.50

The cost for 1 comic book was $3.50.

_____

You know that the total cost of a transaction is the sum of the costs of each part. When all the parts have the same value, we can multiply the cost of one part by the number of parts.

Answer:

2y-1

Step-by-step explanation:

Answer: y = 1/2 in decimal form = 0.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*y+3-(4*y+2)=0

olve  :    -2y+1 = 0  

Subtract  1  from both sides of the equation :  

                     -2y = -1

Multiply both sides of the equation by (-1) :  2y = 1

Divide both sides of the equation by 2:

                    y = 1/2 = 0.500

Step-by-step explanation:

50-10 x 2-40-30 x 6-60=0

20=5x-13+6x

We move all terms to the left:

20-(5x-13+6x)=0

We add all the numbers together, and all the variables

-(11x-13)+20=0

We get rid of parentheses

-11x+13+20=0

We add all the numbers together, and all the variables

-11x+33=0

We move all terms containing x to the left, all other terms to the right

-11x=-33

x=-33/-11

x= 3

Answer:

3

Step-by-step explanation:

First, write the equation.

20=5x-13+6x  Combine like terms on the right side.

20=11x-13       Add 13 on both sides.

+13     +13

33=11x             Divide both sides by 11.

A is -7 and b is -4 if you add them it would be positive 11 because a negative plus a negative is a positive. Here's this to keep in mind:

+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5

−(−)                                                                         6−(−3) = 6 + 3 = 9

+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
