<span>To solve this we have to set up our inequality expressions with the given information:
5 * (x + 27) >= 6 * (x + 26). Now that we know the expression we can solve for x to determine the solution set. We have to rearrange and simplify the equation as follows: 5x + 135 >= 6x + 156. Now we get the x terms on one side and the integers on the other so we can solve for x: -21 >= x . The solution set would be that the number is less than or equal to -21.</span>
Answer:
E = (1, 2)
Step-by-step explanation:
You want ...
(E -G) : (O -E) = 3 : 4
4(E -G) = 3(O -E) . . . . . . . . "cross multiply"
4E -4G = 3O -3E . . . . . . . . eliminate parentheses
7E = 4G + 3O . . . . . . . . . . . add 3E+4G
E = (4G +3O)/7 . . . . . . . . . .divide by 7
E = (4(-5, -1) +3(9, 6))/7 = (-20+27, -4+18)/7 = (7, 14)/7 . . . . fill in G and O
E = (1, 2)
2x + 5y = 270
Two times the amount of wheeled backpacks. Let x = wheeled backpacks.
Five times the amount of non wheeled backpacks. Let y = non wheeled backpacks.
Total backpacks will be 330 so 330 - 60 = 270
Therefore you get 2x + 5y = 270
