The basic facts she used to help her estimate are (c) 28 + 7 and (d) 30 + 5
<h3>What are estimates?</h3>
Estimates are approximated calculations that are used in place of an actual calculation
The expression is given as:
28 + 7
When the numbers are approximated to the nearest 5, we have:
30 + 5
Hence, the basic facts she used to help her estimate are (c) 28 + 7 and (d) 30 + 5

Answer:
Step-by-step explanation:
I think its the median
The expression is log 4 x = 5
Answer:
x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z
or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z
Step-by-step explanation:
Solve for x:
sin(x) = 1.5
1.5 = 3/2:
sin(x) = 3/2
Take the inverse sine of both sides:
Answer: x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z
or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z
It's A ....just divide numerator and denominator of the both and see which is equal.....and it's A
