Scilla [17]
Diana had chocolate, and ate some, leaving 0.75 of it for Sarah.

Sarah ate 18.5 grams of it and return the rest to Diana, which was 65% of the original chococate.

how much chocolate did Diana have at the beginning?

and the solution is:

0.75x-18.50=0.65x

0.75x-0.65x=18.50
0.1x=18.50
x=185

so Diana had 185 grams of chocolate.

OleMash [197]

Answer:

<h2>          y = 2x + 6</h2>

Step-by-step explanation:

M=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-0}{-2-(-3)}=\dfrac21=2

y = 2x + b  passes through point (-3, 0), so:

0 = 2(-3) + b

0 = -6 + b

b = 6

Therefore the equation:  <u>y = 2x + 6</u>
