84 cents a pound divide 2 1/4 by 1.89 equals 0.84
Answer:
11
Step-by-step explanation:
cross multiply - 2(2x-4) = 3(x=1)
4x - 8 = 3x + 3
4x - 3x = 3 + 8
x = 11
I honestly do not know what to say here: it's already in decimal form. Please, if you made a mistake while typing in the problem, tell me.
The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
The answer will be reflect (2, - 3 ) in x = -1
