Explanation

Let's set up the equations based on the given information:

1. 2p + 3c = 86 (Equation 1)

2. 4p + 1c = 112 (Equation 2)

where p is the price of a pen and c is the price of a pencil.

To solve for p and c, we can use substitution or elimination. Let's use the elimination method.

First, solve Equation 2 for c:

4p + c = 112

c = 112 - 4p

Now, substitute this expression for c into Equation 1:

2p + 3(112 - 4p) = 86

2p + 336 - 12p = 86

2p - 12p = 86 - 336

-10p = -250

p = 25

So, the price of a pen is 25.

Explanation

The pattern in the series is as follows:

9 + 1 = 10

10 + 3 = 13

13 + 6 = 19

The next difference should be +9:

19 + 9 = 28

So, the correct answer is 28.

• PowerPoint is a presentation software, not an image editor.
• It is used to create slideshows, presentations, and lectures.

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

• Divide 3 by 1/3: 3 ÷ 1/3 = 3 × 3 = 9
• Subtract 9 from 9: 9 - 9 = 0
• Add 1 to 0: 0 + 1 = 1

So, the solution to the equation is 1.
