Profit = revenue - expenses
250 = 25x - (12x + 60)
250 = 25x - 12x - 60
250 = 13x - 60
250 + 60 = 13x
310 = 13x
310/13 = x
23.85 = x....so she would have to sell 24 purses
Answer:
9x^3-17x^2-x+7
Step-by-step explanation:
Distribute the negative you'll get
(12x^3-8x^2)+(-3x^3-9x^2-x+7)
Combine like terms
12x^3-3x^3=9x^3 , -8x^2-9x^2=-17x^2 , -x , +7
Putting it all together:
9x^3-17x^2-x+7
Word problems commonly include mathematical modelling questions, where data and information about a certain system is given and a student is required to develop a model.
We have been given that
4 3/4 + 2 1/4 = ?
Convert into word problem .
Bob has 4 apples in which 3/4 apples are good and also he has 2 bananas in which 1/ 4 bananas are good . Then find out how much of amout i good condition ?
Solution - 4 × 3/4 = 3
and 2 ×1/4 = 1/2
then total good = 3 + 1/2 = 3.5
If it is factor problem then
Solution -.
4 3/4 + 2 1/4 = ?
simlify the equation
= 19/4 + 9/4
= ( 19 + 9 ) / 4
= 28 / 4
= 7.
