<span>1/2 / -2/5 + (-1/4)
= 1/2 * (-5/2) - 1/4
= -5/4 - 1/4
= -6/4
= -3/2
hope it helps</span>
Answer:
$960
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

<em>I = interest amount
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal form)
</em>
<em>t = time
</em>
The first step is to change 3% into a decimal:
3% ->
-> 0.03
Now, lets plug in the values into the equation:


Jameson will be charged $960 of interest after 4 years.
<span>In order to find the average, you have to find the total, and then divide by the amount of days, which in this case is 5. The total is 395/5 = 79. Therefore, the average number of pies sold each day is 79</span>
Mathematical expressions allow us to relate numbers using mathematical symbols to make calculations. some examples are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
<h3>What is a mathematical expression?
</h3>
A mathematical expression is a sequence of characters that are intended to express a general relationship between the terms expressed in the formula.
Mathematical expressions generally have symbols like:
- Add +
- Subtraction -
- Multiplication ×
- Division ÷
- Exponent
- Equal =
- Parentheses ()
According to the above, some examples of mathematical expressions are:
- 2 + 3 = 5
- 4 - 1 = 3
- 2 × 2 = 4
- 4 ÷ 2 = 2
- 2² + 1 = 5
- (1 + 2) + (2 × 1) = 5
- (2 + 3) - 4 = 1
- (2 + 2)² ÷ 4 = 4
- (2 ÷ 4)² × 4 = 1
- (2 + 2)² (4 ÷ 2) - (2 × 4)(5 - 1) + 5 = 5
