irina1246 [14]

Answer:

Step-by-step explanation:

Given that:

Percentage of blue, orange and green = 10%

Percentage of yellow, red and purple = 23.3333%

Number of skittles in bag by color :

Red = 137

Orange = 39

Yellow = 130

Green = 39

Blue = 43

Purple = 112

According to the color distribution :

Number of blue, orange and green should be the same and also number of yellow, red and purple skittles must be the same.

Total number of skittles :

(137 + 39 + 130 + 39 + 43 + 112) = 500

10% of the total = 0.1 * 500 = 50

Hence,

We should have 50 blue, orange and green skittles

23.33333% of total = 116.666 (about 117 skittles of yellow, red and purple color)

2x + y = -4<br> 5x - 3y = 1<br><br> Solve with elimination method

Ivanshal [37]

Answer:

For the first equation the answer for "X" will be,

$x = \frac{ - 4 - y}{2}$

if you want me to solve for y instead then the answer will be,

$y = - 4 - 2x$

for the second equation the answer for "X" will be,

$x = \frac{1 + 3y}{5}$

If you want me to solve for y instead then the answer will be,

$y = - \frac{1 - 5x}{3}$
