Answer:
AC = 52
Step-by-step explanation:
the diagonals of a square are congruent and bisect each other, hence
AC = BD
2(3x - 4) = 10x - 48
6x - 8 = 10x - 48 ( subtract 10x from both sides )
- 4x - 8 = - 48 ( add 8 to both sides )
- 4x = - 40 ( divide both sides by - 4 )
x = 10
⇒ AC = 2(3 × 10 - 4) = 2 × 26 = 52
3000 is your answer. 3000 x 3 is 9000. :)
45 students for performance
30 students for jazz
19 for both
Add the two bands first
45 + 30 = 75 students
Since there are 19 for both and the question is how many students signed up for only one of the two bands (not both bands).
75 - 19 = 56 students signed for one of the two bands
So you're good to go
I think I’ve done this right maybe not but.
9). -0.35
I don’t know 10
By flipping the fraction of -3/7, you will get the fraction of -7/3 or - 2 1/3.
Therefore, the reciprocal of -3/7 is - 2 1/3.
Hope this helps!
