Answer:
18
Step-by-step explanation:
xy + 4 = 40
xy = 40 - 4
xy = 36
What two numbers can b multiplied to give 36? Then add them.
9 + 4 = 13
18 + 2 = 20
6 + 6 = 12
12 + 3 = 15
The odd option is 18
Answer:
3 hours 40 minutes.
Step-by-step explanation:
We are told that we have 1320 garments and it takes an employee 20 seconds to tag a garment.
1 employee tags one garment in 20 seconds.
So garments tagged by 1 employees in 1 minute will be
garments.
2 employees will tag 3*2=6 garments in 1 minute.
To find the total time it will take two employees to tag all the garments we will divide total number of garments by 6.


Therefore, it will take 220 minutes or 3 hours and 40 minutes for 2 employees to tag 1320 garments.
Answer:
6
Step-by-step explanation:
Inverse proportion.
z = k/w
z = 3, w = 4
Solve for k constant.
3 = k/4
(4)3 = (4)k/4
12=k
The value of k constant is 12.
z = k/w
Put w as 2 and k as 12 and solve for z.
z = 12/2
z = 6
The value of z when w equals 2 is 6.
