Mathematics High School

Mrs. Nelson gave her students a task: Start with the expression 2x^3. Add, subtract, multiply, divide, or use exponents to make a new expression that is equivalent to 16x^10. The answers of several students are shown below. For each student, determine if they are right or wrong. Then explain why using your exponent rules.

Susana:

x^7(2x^3+14x^3)

Right or Wrong?​

Why?

Answers

Answer 1

Answer:

Right

Step-by-step explanation:

The problem is right because if you solve it the solution is 16x^10

x^7(2x^3+14x^3)

Collect like terms

x^7 x 16x^3

Calculate the product

16x^10

2 Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn. Write the inequality to represent the number of weeks (w) will he need to save in order to save at least $75? (You are not solving this inequality.)​

Answers

Answer:

15 + 5w ≥ 75

Step-by-step explanation:

Let the number of weeks be represented as w.

We are told from the question that:

Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn.

The word "at least" in mathematics means equal to or greater than and it is represented by the sign ≥

Therefore, our inequality equation is written as:

15 + 5w ≥ 75
