Answer:
yes I agree with you I don’t think I’ve done that but it obviously gets other people annoyed when someone says the answer is no in file and maybe it really could be sometimes, but for me it’s annoying when people do that because I then have to open the file up and go to another tab.
But I agree with you that if you download the file it can take points away.
Step-by-step explanation:
yes.
Step-by-step explanation:
you have to know how many inches make a foot or vice versa the you do simple proportion by equating the inches to the foot to get the answer. simple as abc
<span>120/x - 120/(x+10) = 1
120x + 1200 - 120x = x(x+10)
1200 = x^2+10x
x^2 + 10x - 1200 = 0
(x+40)(x-30) = 0
Positive solution:
x = 30 km/hr (rate on the 1st trip)
x+10 = 40 km/hr (rate on the return trip)</span>
338+188=526
188+338=526
Commutative property

when adding numbers, order doesn't matter. This fact is called the commutative property.
