X+6≠x, unless X ≠ x.
small x minus 6 would be equal to big X.
So you estimate 715 to mk it as 700 then divide it by 8
It is 45 because complementary means 90
2. Some fractions could be different in denominator and numerator so you'll have to make all denominators the same in order to order them. It'll make it easier because the numerator will show which numbers are greater than the other. For example, 1/2 and 3/4, u could convert both to equivalent fractions. Make 1/2 into 2/4 and 3/4 stays the same, 3/4 is greater than 2/4 so it goes first.
3. 2/3, 7/12, 4/9, 1/2, 3/8, 5/24.
It's in this order because their equivalent fractions are,
27/72, 48/72, 36/72, 42/72, 36/72, 15/72.( that's the order they're in in the question)
10. D. Use inverse operations
D. Reverse
Hopefully this helps!
