Answer: 
Step-by-step explanation:
To solve for y, we want to make sure y is isolated. SInce y is already isolated, all we need to do is divide both sides of the equation by 3.
[divide both sides by 3]
or 
Step-by-step explanation:
- 5x²-45=0
- 5x²=45
- x²=9
- x=√9
- x=3
hope it helps.
Use the compound amount formula for continuous compounding:
A = Pe^(rt)
Here,
A = $3000e^(0.055^5) = $3950 (rounded up from $3949.59)
Answer:
x ÷ 1/4
Step-by-step explanation:
<u>Concepts:</u>
- An expression a mathematical sentence that has at least two numbers and a minimum of one math operation (addition, subtraction, etc.) in it. An expression cannot have an = sign in it.
- A variable is an unknown, numerical value in an equation, often represented by the letter x.
<u>Solving:</u>
Let's translate the first part of the expression:
1. "A number"
- Since we're unaware of the number in this expression, we can mark it as a variable, x.
- This means that, so far for our expression, we only have the variable, "x".
2. "divided by 1/4"
- When we're dividing, we use the ÷ symbol to represent that operation.
- Now, let's put the first part of our expression with the second one: "x ÷ 1/4"
Therefore, the expression for this situation is x ÷ 1/4.
The mid point is 15 because it is in the middle of 10 and 20
