If the ratio of wiping is the green peas is 2 to 8 and there are a total of 30 pens how many pens are white

1 answer:

8 0

2x+8x=30. x= #of pens

10x=30. combine like terms

x=3. divide by 10 to isolate (get by itself) x

2(3)=6. the # of white pens are represented by 2x

6 white pens

hope this helped!

Determine the growth factor corresponding to 325% increase

Aleks [24]

Answer:

4.25

Step-by-step explanation:

The growth factor is 1 more than the growth rate. The growth rate is the rate of increase in a given time period.

1 +325% = 1 +3.25 = 4.25

The growth factor is 4.25.

_____

The "increase" amount is what is added to the original. The growth factor is the multiplier of the original.

x + 325%·x = x(1 +3.25) = 4.25x

Write an equation of the line that passes through (7,10) and is perpendicular to the line y=12x−9.

Ulleksa [173]

Answer:

y = - $\frac{1}{12}$ x + $\frac{127}{12}$

Step-by-step explanation:

y = 12x - 9

Slope of line perpendicular to given is m = - $\frac{1}{12}$

P(7, 10)

y - 10 = - $\frac{1}{12}$ (x - 7)

y = -  $\frac{1}{12}$  x +  $\frac{127}{12}$

2. Create a linear function that has a rate of change of 3 and a solution at (6, 12).

Ksivusya [100]

Answer:

$y = 3x - 6$

Step-by-step explanation:

A linear function has the following format:

$y = ax + b$

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.

Rate of change of 3

This means that $a = 3$

$y = 3x + b$

A solution at (6, 12).

This means that when x = 6, y = 12. So

$y = 3x + b$

$12 = 3*6 + b$

$b = -6$

The linear function is:

$y = 3x - 6$
