Answer:

The characteristics of a good math explanation are following:

1. Step by step explanation: The first characteristics of a good math explanation is step by step solution. Do not skip steps because the assumption that the other person knows what you did is not always correct.

2. Justify each step: Mention the reasons behind each step, i.e, theorem, formula, rule etc.

3. Result verification: After find the solution the last step is to verify the solution.

We need to check whether the solution fulfills the given conditions or not. If it satisfy all the given conditions, then it is correct otherwise we need to check our work.

Arnold can read 3 pages in 7 minutes. Brenda can read 8 pages in 14 minutes. Who is the faster reader? Justify your answer.

Mrac [35]

Answer:

Brenda

Step-by-step explanation:

You can divide the number of pages by the number of minutes to find the amount of minutes it takes to read 1 page. For Arnold, 3 pages / 7 minutes = 1 page per approximately 0.43 minutes. For Brenda, 8 pages / 14 minutes = 1 page per approximately 0.57 minutes. Brenda reads slightly faster since 0.57 > 0.43

Greg’s sister Ava is 4 years older than him. If the sum of Greg’s age and 2 times Ava’s age is 35, How old is Ava?

Fofino [41]

Answer:

Step-by-step explanation:

Create an equation: g+(G+4)(2)=35

Parentheses: g+2(G+4)=35

Distributive property: g+2g+8=35

Combine like terms: 3g+8=35

Subtractive property: 3g=27

Division property: g=9

Greg is 9. Since Ava is 4 years older you add 4 to find her age. Ava is 13. You take Ava’s age times 2 ( equals 26) then add Greg’s age (equals 35). And it should equal 35.
