A jar contains 1,200 M&M's and everyday your family eats 1/5th of the candies. After how many days will there be 314 M&M
mrs_skeptik [129]
The equation is 314 = 1,200 - 240x

1,200 is the number of M&M's it starts with
The problem said the family eats 1/5th of the candy every day
1/5 of 1,200 is 240
It is a -240 because the amount of m&m's is getting fewer each day
The x stands for the number of days

Sorry but I'm not sure if I could answer your problem exactly
The answer is 3.69 days
Because there isn't an exact day that there would exactly 314 M&M's left

Answer:

y = 6x

Step-by-step explanation:

You can easily find the slope by using slope formula:

(y2-y1) / (x2-x1) (the numbers are subscript)

E.g: (24-12) / (4-2) = 12/2 = 6

m(slope) = 6

Hope this helped :)

(You can also check if it’s correct by inputting the coords into the equation, seeing if all solutions are aplicable).

The graph below shows the line of best fit for data collected on the number of cell phones and cell phone cases sold at a local
Dovator [93]

Answer:

C

Step-by-step explanation:

The equation of a line is given by y-y_1=m(x-x_1)

and

slope (m) is given by:

m=\frac{y_2-y_1}{x_2-x_1}

Where (x_1,y_1) are the first set of point in the line and (x_2,y_2) is the second set of point

<em>Let's take 2 points arbitrarily. (0,0) & (25,20)</em>

<em />

<em>Let's plug it and find the equation:</em>

<em>m=\frac{20-0}{25-0}=0.8</em>

<em>Now</em>

<em>y-y_1=m(x-x_1)\\y-0=0.8(x-0)\\y=0.8x</em>

<em />

<em>C is the correct answer.</em>

There are 7 coins that look identical.One of the seven coins weighs slightly less than the other 6. Using a balance scale, how c
RoseWind [281]
Start by putting two coins on each side of the scale. If one side is higher, then the light coin must be in that pair (use a second weighing to determine which of that pair is the lightest.)
If the initial weighing shows the two pairs to be even, discard those four and go to the three others. Put two of the coins on the scale - one on each side. If one side stays higher, that coin is your light one. If however they are equal, the final unweighed coin must be the lighter coin.
