First we know that a dozen is 12
so She makes 12×15 cookoes which is
180 cookies
so lets put it in an equation.
36 cookies = 1 cup butter
180 cookies = X
The criss cross method
36 X = 180 cup of butter (notice here that the cookie cancelled out)
dividing each side by 36 we get
5 cups of butter
4^5
4 is the base
5 is the power
Same as writing it like
4 x 4 x 4 x 4 x 4
Answer:
2x- 3y = - 6
Step-by-step explanation:
given
y -
x - 1 = 0
multiply all terms by 6 to eliminate the fractions
3y - 2x - 6 = 0 ( multiply all terms by - 1 )
- 3y + 2x + 6 = 0 ( subtract 6 from both sides )
2x - 3y = - 6 ← in standard form
<em>You have to plug in all the numbers to the circumference formula and solve!</em>
circumference formula:

<em>or</em>

3.14(12.5) = ?
39.25
<em>The answer is</em>
d. 39.25
{ y=2x+2
{ y=4x-2
2x+2=4x-2
x=2
y=2 ⋅ 2+2
y=6
(x,y)=(2,6)
——
Check solution:
{ 6=2 ⋅ 2+2
{ 6=4 ⋅ 2-2
{6=6
{6=6
