1a:
580 - (580 × .1) - 20
580 - (58) - 20
522 - 20
502
1b:
990 - (990 × .25) - 20
990 - (247.5) - 20
742.5 - 20
722.5
I'm not sure how to solve #2.
40 divided by -2/5 equals -4
so -2/5 x -4 equals 40
answer: -4
Hey there! :D
Looking at the angles, do you see the angle and congruence marks?
Try to find the mark that matches up with <ACB
The only angle that has the same mark is <XZY
Try to match up the way the angle is named as well, the short side first, to the vertex, to the longer side.
The third option would be correct.
I hope this helps!

we are given
Firstly, we will distribute negative sign on right side
Since, we have to move both x and y on anyone side
so, we will add x on both sides
now, we add 7 on both sides
