Answer:
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:
None of the above
Step-by-step explanation:
10 + 10 + 4 + 4 = 28
First choice
4 + 4 + 5 + 5 = 18 X
Second choice
8 + 8 + 3 + 3 = 22 X
Third choice
9 + 9 + 7 + 7 = 32 X
Therefore there is none that are the same.

Step-by-step explanation:
a.The quotient of 25/11 =2, 25-2*11=3 not 14
b.25/11 and 14/11 have the same remainder which is 3
c.The quotient of 3/11 =0, 3-0*11=3 not 14
d.14/11 and 3/11 have the same remainder which is 3
e.The quotient of 14/11 is 1, 14-1*11=3
f.14/11 and 3/11 have the same remainder which is 3
g.Incorrect expression
I. Incorrect expression
To find the case cube of a box in cubic feet, first measure its length, width, and height in inches. Next, multiply all 3 figures together, then divide the result by 1728 to get your case cube measurement in cubic feet.
The answer is -13.
Solution:
= |-4b - 8| + |-1 - b^2| + 2b^3
= |-4(-2) - 8| + |-1 - -2^2| + 2(-2)^3
= |8-8| + |-1+4| + 2(-8)
= |0| + |3| + (-16)
= -13
