What is the result of adding these two equations?<br> 6x + 2y = -2<br> 3x – 2y = -5

Artemon [7]

Answer:

x=-7/9

y = 12/9

Step-by-step explanation:

6x + 2y = -2

3x - 2y = -5

9x = -7 (-2y and +2y eliminated)

x = -7/9

if 3x -2y = -5 then

3 ×(-7/9) -2y =-5➡

-21/9 -2y = -5➡

-2y = -5 + 21/9

-2y = -24/9

Dafna1 [17]

Answer:

A) 0.15

B) 0.36

Step-by-step explanation:

First Box consist 1 red pills and 19 blue pills

second box consist 6 red pills and 14 blue pills

Third box consist 2 red pills and 18 blue pills

a) Prob ( randomly chosen pill is red) $= \frac{1}{3} \times \frac{1}{20} + \frac{1}{3} \times \frac{6}{20} + \frac{1}{3} \times \frac{2}{20}$

$\frac{1}{60} (1+6+2) = 0.15$

b)Prob ( 1 reds and 10 blue pilss) = $\frac{1}{3} \frac{^1C_1\times ^{19}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^6C_1\times ^{14}C_{10}}{^{20}C_{11}} + \frac{1}{3} \frac{^2C_1\times ^{18}C_{10}}{^{20}C_{11}}$

$= \frac{1}{3} 1.106 = 0.368$
