B. 32; 48 should be the answer
First, you have to make the denominators the same.
5 1/3 is now 5 4/12
4 3/4 is now 4 9/12
5 4/12
- 4 9/12
4 16/12
- 4 9/12
7/12
Hope this helps!
Answer:
3 ≤ w ≤ 4
Step-by-step explanation:
the statements are 3 ≤ w and 4 ≥ w ( or w ≤ 4 )
These can be combined into the single inequality
3 ≤ w ≤ 4
Answer:
D. 9990 possible combinations
Step-by-step explanation:
The first digit has 10 choices (can be all of them), the second digit also has 10 choices. The third and fourth digits also have 10 choices.
Multiply them together you get 10*10*10*10 = 10000 possible combinations.
But since all 4 characters cannot be the same, we subtract 10 from 10000 (there are 10 combinations which the 4 characters are the same: 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, and 0000) and we get 9990.
Answer:
"1. (−3, −7)"
Step-by-step explanation:
If we have a point (x,y),
1. Reflection across x axis makes it (x, -y)
2. Reflection across y axis makes it (-x, y)
So we see x-axis reflection simply changes sign of y coordinate & y-axis reflection changes the sign of x coordinate (keeping x and y same, respectively).
Thus, the question asks to reflect (-3,7) about x-axis, so we change sign of y coordinate, 7 becomes -7. THus, the point becomes:
(-3,-7)
Answer choice #1 is right.
