### What does equivalent expression mean in math?

It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.

### How do you find 40 percent as a fraction in simplest form?

The word "percent" means "per 100" so your percentage becomes a fraction with the denominator 100. 40% = 40/100 Simplify by dividing both the numerator and denominator by the same number. This number will be the Greatest Common Factor (GCF) of the two numbers. Here, the GCF is 20, because 40 = 2 x 2 x 2 x 5 100 = 2 x 2 x 5 x 5 and the common factors 2 x 2…

### What is the value of 2 to the power 50?

Lets take a short cut that can be beneficial to working with larger powers. 1. Lets reduce the 50 to 10 to start. 210 = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 1024. 2. Now you can take that 1024 and multiply it by 1024. 1024 x 1024 = 1,048,576 Which is now the same as 220 3. Again take your 1,048,576…

### How much is land in Thailand?

The equation x-2=0 is the same as x=2, which has an undiefned slope. Slope is found by (change in y/change in x). x = 2 is a vertical line, so there is no change in x (0), which means the equation would then by (change in y/0) which is undiefned (you can't divide by zero).To actually solve the equation you really don't need to solve but just know what a slope of undiefned means. The…

### What is Fifteen more than half a number is 19 in equation?

"More" in a word problem means addition is involved. "Half" indicates division by 2 (or multiplication by 1/2). "A number" means a variable, so we can us x. Finally, "is" mean equals. So, 15 more than half a number is 19 would be represented as follows: 15 + x/2 = 19 Solving this, we get: 15 + x/2 = 19 x/2 = 4 x = 8
