Answer:
x= 13
Step-by-step explanation:
(X+2) 3 = (x-4) 5
distribute on both sides: 3x + 6 = 5x - 20
add 20 to both sides: 3x + 26 = 5x
subtract 3x from both sides: 26 = 2x
divide both sides by two: 13 = x
You plug the x value into whichever function it applies to. X represents the number of shirts ordered. So for example, the first question asks the total cost if you order 57 shirts. Look at the piecewise function. If says is x>50 (or equal), you use the equation 14x + 20. 57 is greater than 50 so plug it into the equation. (14)(57) + 20 = 818. You should be able to do the rest now. If you have any more questions, you can ask.
51 is the highest multiple you can take from 53
One way to find this out is take 53-30 and you get 23 from this you know 21 is the highest multiple you can get so 30+21 = 51
51/3 is 17 so each student gets 17 blocks and the thus remainder is 2
Another way is to divide 30 and 21 by 3 and add them both together and you will get the same answer
Do always make the numbers easier to solve and save time scrambling..
