Nina is bouncing on a trampoline her fourth bounce is 6ft high each bounce afterwards is two thirds as high as the bounce before
V125BC [204]

Answer:

8/3ft

Step-by-step explanation:

To find how high she would bounce, we need to first understand that her height of each jump would be multiplied by 2/3 given that each bounce afterwards is two thirds as high as the bounce before.

We can then set the equation:

6 x 2/3 x 2/3

=6 x (2/3)^2

=8/3

Therefore the answer is 8/3 ft.

Hope it helps!

What is the simplified form of the expression 3a + 7 - a - 7
Sonja [21]
You can simplify expressions by simplifying parentheses by using the distributive property and combing like terms.

Combining like terms is the process of adding up numbers with the same variable(s) and exponent. If a term does not have an exponent then an exponent of 1 is implied.

There is no parentheses in the expression 3a + 7 - a - 7 
But, there are like terms in the expression.

Which are the like terms?

3a and a are both like terms. They both have the same variables and they both have the same exponent.

7 and -7 are like terms, too.

3a + 7 - a - 7
2a

So, 2a is the simplified version.
