The answer is 9/1 because 54/6 is and and so are all the others
Xiao should have written this
Xiao's mistake was that
he forgot to put 3 times 30 so it
could be 90.
3(20) + 3(30)
60 + 90
150
Answer:

Step-by-step explanation:
1) Multiply both sides by 3.

2) Use this rule: a/b × c = ac/b.

3) Simplify 4 × 3 to 12.

4) Simplify 12/9 to 4/3.

Therefor, the answer is, t = 4/3.
and in decimal form it would be, 1.333333.
When you write a number that is less than 1 in scientific notation how does the power of 10 differ from when you write a number greater than 1 in scientific notation?
Answer : In scientific notation all numbers are written in the form m × 10ⁿ. If the number is less than 1, ten is raised to a negative power, so : m × 10⁻ⁿ.
Example : a decimal number less than 1 is 0.02 = 2 x 10⁻² in scientific notation.
Hope this helps!
