2 1/3 + 1 3/4 = 4 1/12
4 1/12 miles in total.
The ratio is 4:7 because since the ratio is red apples to green apples theirs 4 red apples and theirs 7 green
The friend is wrong - According to the Pythagorean Theorm, if c is the hypotenuse and a and b are opposite sides then c^{2} = a^{2} + b^{2}
if c=65 inches, a=16 inches and b = 63 inches, then
65^{2} =16 ^{2} + 63^{2}
right hand side of the equation = 256 + 3969 = 4225
left hand side of the equation = 65^{2}= 4225
So we see, left hand side = right hand side
Hence the theorm is proved.
-5, -4, 0, 2, 3. From smallest to largest
Answer:
a + 20 = 7*12 (multiplied both sides by 12)
a + 20 = 84 (calculated 7*12)
a = 84 - 20 (subtracted 20 on both sides)
a = 64 (calculated 84-20)
