6^9 x 6^-7 = 6^2
x= -7
Hope this helps :)
The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.

Answer:
Step-by-step explanation:
b + n = 192
n = 5b
b + 5b = 192
6b = 192
b = 192/6
b = 32 <==== 5 beads per bracelet
n = 5b
n = 5(32)
n = 160 <==== 160 beads per necklace
Is there more to the problem?
