You divide 13 into 250 parts which gives you 0.052, multiplied by 100 will give you the percent: 5.2%
3x - 7 = 2x + 7
3x - 2x = 7 + 7
x = 14
2x + 7 + 12y + 1 = 180
2(14) + 7 + 12y + 1 = 180
12y + 36 = 180
12y = 144
y = 12
Answer
x = 14 and y = 12
For volume you would do 20 x 8.5 x 7.5 = 1275 ft^3
For surface are you would add up all the area of the faces
left and right face = 8.5 x 7.5 = 63.75 each
front and back = 20 x 8.5 = 170 each
top and bottom = 20 x 7.5 = 150 each
total = 767.5 ft^2
Which one they both is really easy
They both have the same denominator or bottom half of the fraction so you need to compare the numerators. 6 is more than 4 so Martin bought more fruit than Jack. Hope this helps.
