NP and MQ are medians of triangle NML. Find XQ if MQ=3x-3 and XQ=2x-6. PLEASE HELP

Step-by-step explanation:

We assume that point X is the intersection point of the medians. Then ...

  MQ = 3XQ

  3x -3 = 3(2x -6)

  3x -3 = 6x -18 . . .  eliminate parentheses

  15 = 3x . . . . . . . . . add 18-3x

  5 = x . . . . . . . divide by 3

Now, we can find XQ:

  XQ = 2x -6 = 2(5) -6

  XQ = 4

boxplot e is the answer

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
