If Johnny can run 2 miles in 15 minutes, How many miles can Johnny run in 32 minutes? Please round to the nearest tenths place.
We will write this as a fraction. 2/15 = x/32 To find x, we will use a criss cross method multiply x by 15 and multiply 2 by 32 15(x) = 2(32) 15(x) = 64 (divide both sides by 15) x = 4.26667 x = 4.3 miles (rounded to the nearest tenths place)
Find the area and the perimeter of a rectangle with sides equal to 3in and 8in.
Area = L x W (length x width) Area = 8 x 3 Area = 24in Perimeter = 2L + 2W (add all sides together) Perimeter = 2(8) + 2(3) Perimeter = 16 + 6 Perimeter = 22
Altogether three students have 23 apples. Timothy has 8 apples. Tina has X apples. Taylor has 3 times the amount of apples as Tina. How many apples does Tina have?
We don't know X but we can find it. We know that Taylor has 3 times X and Timothy has 8. All together we have 23. 3X + 8 = 23 3X - 8 = 23 - 8 (subtract 8 from both sides) 3X = 15 (divide 3 on both sides to get X by itself) X = 5 Tina has 5 apples.
