Answer:b=-10.5, a=31.5
Step-by-step explanation: 3b=-a , -3b=a
a+b =21
-3b+b = 21
-2b=21
b=-10.5
a=-3b
a=-3*-10.5=31.5
Answer:
Step-by-step explanation:
Given diameter (d) = 13 m
circumference
= π * d
= 3.14 * 13
= 40.82 m
Answer:
No
Step-by-step explanation:
you can see that they can not go into each other and come out correct so the answer would have to be no (we were working on this same thing)
18/25, 51/75, 33/50, 13/20, 3/5
Nothing to confuse. The number of partners are 3. $2.03 is the amount of tips they receive per hour. So devide $2.03 to get the amount of tip that one partner receives hourly, which is $0.68.
Now to create a function, it's clearly that the number of hours is the variable x so it would change depending on how many hours each employee has worked. So the equation will be :
y = 0.68x
Apply the number of hours of each employee and get the total of tip they receive per hour.
Edit : if the partners who are working is unknown you can write the equation based on this :
y = ((2.03)x)/n
n is the number of partners who are working so the amount of tip they will receive will depend on how many employees are working in the cafe.
Hope this helps !
