Jessica had a bag of candies. She gave 1/8 of her candies to judy. Then jessica gave 3/7 of the candies she had left to Reggie.
AlexFokin [52]

Answer:

Jessica had 32 candies at the beginning.

Step-by-step explanation:

Let the number of candies Jessica had at the beginning be x.

Candies gives to Judy = \frac{1}{8}x.

Now, candies left with Jessica is x-\frac{1}{8}x=\frac{7x}{8}.

Candies given to Reggie is \frac{3}{7} of \frac{7x}{8}.

∴ Candies with Reggie is \frac{3}{7}\times\frac{7x}{8}=\frac{3x}{8}.

Candies left with Jessica after giving to Reggie = \frac{7x}{8}-\frac{3x}{8}=\frac{4x}{8}.

Now, Jessica lost 75% of what she had left. So, 75% of \frac{4x}{8}.

∴ Candies lost = \frac{75}{100}\times\frac{4x}{8}= \frac{3x}{8}

Now, candies left with Jessica = \frac{4x}{8}-\frac{3x}{8}=\frac{x}{8}.

As per question,

Candies left with Jessica at last is 4. So,

\frac{x}{8}=4

x=32

Hence, Jessica had 32 candies at the beginning.

Find the slope , I NEED HELPPP
Gnesinka [82]

Answer:

Hi there!

Your answer is: 1/2

Step-by-step explanation:

Slope is determined by rise/run. How many units the graph increases divided by how many units it goes left or right!

In your graph, we see that it rises 1 unit per 2 units it goes right. This means that your slope is 1/2!
