Question

I need a lot of help please ):

Answer 1

Answer:

The answer are

CX=10/3

ML=76

Step-by-step explanation:

NUMBER 4

We know that the averages are divided 1 to 2 by the base

$then \: \\ xc = \frac{1}{3} xf \\ = \frac{1}{3} \times 1 0 = \frac{10}{3}$

NUMBER 5

$ml = \frac{2}{3} mr \\ then \\ 10x - 4 = \frac{2}{3} (12x + 18) \\ 30x - 12 = 24x + 36 \\ 6x = 48 \\ x = 8 \\ then \\ ml = 10 \times 8 - 4 = 76$
