Answer:
B and D
Step-by-step explanation:
B -> -1.4z multipled by 40 is - 56z, 0.7 multipled by 40 is 28, thus giving us - 56z + 28.
D -> When we expand (8z - 4)(-7) we will get -56z + 28 as 8z multipled by - 7 is - 56z (remember positive times negative equals negative) and - 4 multipled by - 7 is 28 (negative times negative equals positive)
1) u + 2 = 4
u = 2
2) -5 = s - 3
-2 = s
3) 5/13t = -9
t = -9 × 13/5
t = -39/5
t = -7 4/5
4) 6 = x + 2/3
x = 6 - 2/3
x = 5 1/3
5) 13 + w/7 = -18
w/7 = -18 - 13
w/7 = -31
w = -31 × 7
w = -217
6) 17 = -13 - 8x
-8x = 17 + 13
-8x = 30
x = 30/-8
x = -15/4
x = - 3 3/4

*Also, next time, please post your questions individually, so that you could get a quicker answer, thanks! :)
technically, yes because there is a mathematic formula behind numbers going on as long as it is a repeated pattern throughout the new numbers
Answer:
31.8 in^2 per slice
Step-by-step explanation:
to get the radius (r) you divide the diameter (d) by 2, so its 18/2 which is 9, then you plug 9 into the formula for a circle
A=πr2=π·92≈254.469
thats the area for the whole pizza, then you divide that by 8 (for the 8 slices) which is 254.47/8, which gives you 31.80875
31.80875 rounds to 31.8 in's, but you have to make sure its in^2 because its area
