X=45 since 90-45=45
Hope this helps
B because distributive property goes like this:
a(b+c)
a(b)+a(c)
That's just an example though
3/4 lb × 10 chunks =
3/4 × 10 =
30/4 = 7 2/4 = 7 1/2 lbs
D-10-2d+7 = 8 + d- 10 -3d
d-2d-10+7 = 8-10 +d -3d
-d-3=-2-2d
-d+2d=3-2
d=1
Final answer: C. d=1

We then do (180-19)
