HELP HELP HELP HELP ME!!!!!!!!!!!!!!!

Answer:

$l=\frac{A-\frac{1}{2} \pi w^2}{2w}$

Step-by-step explanation:

We essentially need to solve for l; in other words, we must isolate it to one side.

First, notice that the term $\frac{1}{2} \pi w^2$ doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by $\frac{1}{2} \pi w^2$ :

A - $\frac{1}{2} \pi w^2$ = 2lw

Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:

$l=\frac{A-\frac{1}{2} \pi w^2}{2w}$

Francesca is painting a picture of the purple flowers in her garden. She mixes paint to make the perfect color for each type of

aniked [119]

Find total ounces mixed for each flower:

Daisies = 2+5 = 7 ounces

Tulips = 3 +6 = 9 ounces

Now find the ratio of purple to white for each one:

Daisies = 5/7 = 0.714

Tulips = 6/9 = 0.666

Daisies have more purple so would be the darker ones.

Does (2,0) work as a solution to the systems of equations to lines 3x+y=6 and 3x-y=6

fenix001 [56]

Answer:

Yes

Step-by-step explanation:

To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.

3x + y = 6:

$3(2) + 0 = 6$
$6 + 0 = 6$
$6 = 6$
(2,0) is a solution to this equation.

3x - y = 6:

$3(2) - 0 = 6$
$6 - 0 = 6$
$6 = 6$
(2,0) is a solution to this equation.

Therefore, the answer is yes, it does work as a solution.
