Answer: A) + a
add the two equations together to get A.
the ones cancel eachother out and you cant add to a
Simplify. Combine like terms.
7 - 9 = -2
4t - 2 = -6 + 6t
Isolate the t. Note the equal sign. Add 2 to both sides, and subtract 6t from both sides
4t (-6t) - 2 (+2) = -6 (+2) + 6t (-6t)
4t - 6t = -6 + 2
Simplify
-2t = - 4
Isolate the t, divide - 2 from both sides
-2t/-2 = -4/-2
t = -4/-2
t = 2
t = 2 is your answer
hope this helps
Well if 10/100 are left handed, that means that 10% of all the kids are left handed and 90% of the kids are right handed. so the probability that 80% of the students selected are right-handed, is likely.
the filaments are called hyphae (singular, hypha). Each hypha consists of one or more cells surrounded by a tubular cell wall. A mass of hyphae makes up the body of a fungus, which is called a mycelium (plural, mycelia). The hyphae of most fungi are divided into cells by internal walls called septa (singular, septum).
