She is losing $20, so it indicates a negative number when really it is positive
Answer:
x = 11, 10 or 9
Step-by-step explanation:
1) y= 1.20(2)+.95(4)
2) y= 6.20*.05= .31
3) 6.20+.31= 6.51
4) 100-6.51= 93.49
Items bought:
x packs of pencils
twice as many packs of erasers, number of packs of erasers = 2x
three times as many rolls of tape, number of rolls of tape = 3x
Now, we have two possible scenarios:
1- The three items cost the same:
cost of one pack of pencils = cost of one pack of erasers = cost of one roll of tape = m
total amount spent = xm + 2xm + 3xm = 6xm
2- The three items do not cost the same:
cost of one pack of pencils = m
cost of one pack of erasers = n
cost of one roll tape = p
total amount spent = xm + 2xn + 3xp = x(m + 2n + 3p)
Answer:
x^2 - 16x +60
Step-by-step explanation:
X^2 -17x + 70 + x -10
x^2 -17x + x +70 - 10
=
