Ashley is wrong. I have no clue what a placement chart is but I'll solve it anyway.
(5/10)x100 = (5x100)/10 = 500/10 = 50
Answer:
Step-by-step explanation:
in tri ADC and tri BDC
∠ADC =∠BDC = 90
DC is common
AD = BD (given)
triangle ADC ≅ tri BDC by SAS congruency
hence AC = BC by CPCT ( congruent parts of congruent triangles)
hence, BC = 13
First, start at zero. Now, because we are multiplying -4 by 3, we will jump over by 4 to the left ; 3 times on the number line. We should reach -12, and if we check our work, 3 x -4 = -12.

1152
I also put this on your last post
Answer: x > 5 and x < 10
Step-by-step explanation:
in the first inequality, divide both sides by -2 and remember to reverse the inequality sign when you divide by a negative number.
For the second one, add 4 to both sides.
