Answer:
z=12
Step-by-step explanation:
subtract both sides by 4:
-z/3=-4
then multiply both sides by -3:
z=12
This sequence starts with an initial set; let’s call it s1. This set contains 20 cans, and every set following would have two less cans than the last set. So,
s1=20
s2=s1-2=18
s3=s2-2=16
•
•
•
s9=s8-2=4
How many cans in the display represents the value of each set added together, so we can denote this as
s1+s2+s3+...+s9
and replacing with values:
20+18+16+...+4 = 108
The number of cans in the display equals 108.
(The set notation seems weird, but by practicing this application now, the Calculus version will seem easier.)

Hello using PEMDAS I came up with 63
division and multiplication first then add and subtract leaving you with 63
Answer:
They cost 730 all together.
Step-by-step explanation:
One the surface area of the hall is 310m^2.
so, 310 divided by 25 is 12.4, which means they need 13 tin of paint.
The cost for it is 13*10 which is 130.
For the area of the floor, it is 40*15, which is 600m^2.
Which costs 600.
So, 600+130=730.
