Step-by-step explanation:

The student put 5 in for y and 1 in for x.  It should be x=5 and y =1

y = 3x+2

1 = 3*5 +2

1 = 15+2

1 = 17

This is not true so this is not a solution

How many different ways can the students at a school select the president, vice president and secretary from a group of 5?
sattari [20]
Answer: 60 ways.
Explanation: Suppose that we had 5 people, A, B, C, D, and E, and we had to select a P, VP, and S.

For the President, we have 5 different selections.
If we choose a president, then we can only pick 1 from 4 people for the VP.
Using the same logic, we'd have 3 different choices for the S.

Hence, we have 5 · 4 · 3 different ways.

Alternatively, this is:

\frac{5!}{(5 - 3)!} = ^{5}P_3 different ways.

Franklin saved money to buy art supplies
Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had  \frac{3}{10} of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount  be x

then ,

x =  1- (amount used on buying brushes + amount used for buying paints)

x = 1- (\frac{1}{5} + \frac{1}{2})

x = 1- (\frac{2+5}{10})

x = 1- (\frac{7}{10})

x =\frac{10-7}{10}

x =\frac{3}{10}
