The difference (the answer of a subtraction problem) is:
2/7 - 2/5 --> 10/35 - 14/35 = -4/35
The answer sum (the answer of an addition problem) is:
2/7 + 2/5 --> 10/35 + 14/35 = 24/35
Hope this helps.

Answer:
yes since it grows at a constant rate at 7.5 feet/5 days so it should be proportional if you treat it as an algebraic equation and solve for the rate of 1 day's growth but that gives an assumption that no factors would affect the growth and it'll always grow at that exact rate

Step-by-step explanation:
hello :
x=-10 and x=0 because :
for x=0 : 0^3+5(0)²-50(0) = 0
for x= -10 : (-10)^3+5(-10)²-50(-10)=-1000+500+500 =0
Answer:
Step-by-step explanation:
Calculate the number of CD's of the different musical styles
× 72 = = 12 ← dance CD's
× 72 = = 18 ← hip hop CD's
× 72 = 3 × 9 = 27 ← reggae CD's
total = 12 + 18 + 27 = 57
number of rock CD's = 72 - 57 = 15
fraction of rock CD's = =
