In USA the average I.Q. is 98 while the top one average I.Q. country is Hong Kong.
But the I.Q. distribution is given by a polinomial graph, few people with extremely low I.Q. 40~70, a lot between 70~100, some between 100~120, few between 120~140 and extremely low 140+
the numbers inside the () are first number is x second number is y so it is (x,y)
so for y<x the second number needs to be smaller than the first number
so right away (3,3) is not the answer
and then y also has to be greater then 2x-3
so replace x with the fist numbers and see what you get.
(2x2)-3 = 4-3 = -1 since -1 is not greater than -1 the second answer (2,-1) is not right
3rd one (-1,-2) 2(-1)-3 = -2-3=-5
so -2 is greater than -5 and -2 is less than -1 so the 3rd one is the answer
Answer:
1 Simplify \frac{5}{6}x
6
5
x to \frac{5x}{6}
6
5x
.
\frac{5x}{6}=4
6
5x
=4
2 Multiply both sides by 66.
5x=4\times 65x=4×6
3 Simplify 4\times 64×6 to 2424.
5x=245x=24
4 Divide both sides by 55.
x=\frac{24}{5}x=
5
24
Answer:
-1
Step-by-step explanation:
4*-6x=-24x
4*-3=-12
add 12 to both sides to get -24x=24
divide both sides by -24
you end up with x=-1
