So the vs eliminate each other which leaves the ws and the 1,7. Then you add the 2 ws to get 2w and then add the numbers to get 2w=8, then divide 8 by 2 and you get w=4
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:
Kevin is 6
Step-by-step explanation:
Let k represent Kevin's age now. Then Brendon's age now is (k-3). Two years ago the relationship of their ages was ...
k-2 = 4((k-3) -2)
k -2 = 4k -20 . . . . . eliminate parentheses, collect terms
3k = 18 . . . . . . . . . . add 20-k
k = 6 . . . . . . . . . . . . divide by 3
Kevin is 6 now.

1.one solution is the answer
Step-by-step explanation:
Answer:
Matha - Jim = 200 feet.
Step-by-step explanation:
<em><u>Jim's distance</u></em>
J = sqrt(w^2 + L^2)
J = sqrt(300^2 + 400^2)
J = sqrt(900 + 1600)
J = sqrt(2500)
J = 500
<em><u>Martha's distance</u></em>
M = 300 + 400
M = 700 Feet
Answer
M - J = 700 - 500 = 200
Jim walks 200 feet less than Martha.
