Jessica:
2 minutes = 60 jumping jacks
1 minute = 30 jumping jacks
Dale:
5 minutes = 150 jumping jacks
1 minute = 30 jumping jacks
Ans: Yes, both their rates are the same. They both jump at 30/min.
6x - 12y = 24 ⇒ 6x - 12y = 24
-x - 6y = 4 ⇒ -2x - 12y = 8
8x = 16
8 8
x = 2
-x - 6y = 4
-(2) - 6y = 4
-2 - 6y = 4
+ 2 + 2
-6y = 6
-6 -6
y = -1
(x, y) = (2, -1)

Answer:
the number of black tokens in the bag is 2
Step-by-step explanation:
The computation of the number of black tokens in the bag is as followS
Given that
There is 8 green tokens
and, the ratio of green tokens to black tokens is 4:1
So let us assume the black tokens be x
So,
Now do the cross multiplication
x = 2 tokens
Hence, the number of black tokens in the bag is 2
