<span>y=1/6x +4 is already in standard form, but the coefficient 1/6 is not an integer. An integer number is not a fraction number or rational number, so in order we have a standard form with integers coefficients only, multiply each member of the equation by 6. that is 6y =x +24, and 4y = x + 16 is the final answerHope this helps. Let me know if you need additional help!</span>
Fourth test mark should be 86
85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82
2003: 35000
2004: 35000 + 2700 = 37700
2005: 37700 + 2700 = 40400 (and so on)
2006: 43100
2007: 45800
2008: 48500
2009: 51200
Answer:
$0.80
Step-by-step explanation:
percent times the original number equals the part
(%)(start or total cost)= (part of the total cost). you need to know the total cost, so you would fill in the part and the percent. 0.9x=0.72. you use x because you don't know what the total cost is. then you divide both sides by 0.9 to get x by itself and you get that x = 0.8, meaning that the present costs $0.80.
