Heath needs to end up with 10L of solution, 

of which 9L is bleach. So let m = liters of 20% 

solution needed. Then .20m liters of that are bleach. 

He must then add p liters of bleach to make 

a total of 10 L. That is, p + m = 10. So the system is 

m + p = 10, .20m + p = 9. Solving, 

<span>m = 1.25 L 20% solution, and thus p = 8.75 L bleach.</span>

The table shows ordered pairs of the function y = 16 + 0.5x .
Sidana [21]

The missing values represented by x and y are 8 and 20, that is

(x, y) = (8, 20)

The function y = 16 + 0.5x is a linear equation that can be solved graphically. This means the values of both variables x and y can be found on different points along the straight-line graph.

The ordered pairs simply mean for every value of x, there is a corresponding value of y.

The 2-column table has values for x and y which all satisfy the equation y = 16 + 0.5x. Taking the first row, for example, the pair is given as (-4, 14).

This means when x equals negative 4, y equals 14.

Where y = 16 + 0.5x

y = 16 + 0.5(-4)

y = 16 + (-2)

y = 16 - 2

y = 14

Therefore the first pair, just like the other four pairs all satisfy the equation.

Hence, looking at the options given, we can determine which satisfies the equation

(option 1) When x = 0

y = 16 + 0.5(0)

y = 16 + 0

y = 16

(0, 16)

(option 2) When x = 5

y = 16 + 0.5(5)

y = 16 + 2.5

y = 18.5

(5, 18.5)

(option 3) When x = 8

y = 16 + 0.5(8)

y = 16 + 4

y = 20

(8, 20)

From our calculations, the third option (8, 20) is the correct ordered pair that would fill in the missing values x and y.

Berry Farm produces organic tomatoes and strawberries. In June 2021, it transported 130 boxes of strawberries with a price of $1
disa [49]

Answer:

the  revenue recognized is $1,275

Step-by-step explanation:

The computation of the revenue recognized is shown below:

= Number of boxes of strawberries sold to customers × price per box

= 85 boxes × $15

= $1,275

Hence, the  revenue recognized is $1,275

We simply applied the above formula and the same should be considered

Also

= 130 - 85

= 45 boxes would not be recognized as sale is not made

Ber [7]

Answer:

-2

Step-by-step explanation:

-|3n| - 2 = 4

|3n| = -6

3n = -6 or 3n = -(-6)

n = -2 n = 2
