A scale measures weight to the nearest 0.1 pounds
we have to find the most appropriate way to report weigh using this scale
we are given with a few no. of weighs
now lets discuss about weight one by one
200 pounds-it is looking a rounded figure
152 pounds-it is again looking a rounded figure
152.127-it is .not possible because its nearest measure is only 0.1
152.2-it is looking most appropriate as it has one decimal and the given weight scale is also correct to one decimal place
Multiples ! By the patagrium there!!!!!
Let student tickets are x and adult tickets are y
x + y = 516.........x = 516 - y .........(substitute in 2)
3x + 5y = 2046 ......(2)
3(516-y) + 5y = 2046
1548 - 3y + 5y = 2046
2y = 498
y = 249
x = 516 - y = 516 - 249 = 267
so the correct answer is b
I think the answer is the second one, Tessa wasn't sure how far she would swim during the first class. She would swim 3 laps during the second class. The question is confusing, because the equation s+3 is supposed to be the DISTANCE she swam in 2 classes. The problem didn't specify that distance equals laps, but I think the answer is correct
11.y= 300(12)
12. 300x2= 600=24 m so we need 150 more. well 300/2=150 and 12/2= 6 so 24+6=30 30Gal
13. 30x3.75= $112.50
