Answer:
7/10 or 70%
Step-by-step explanation:
6 red chips, 10 blue chips, and 4 yellow chips = 20 chips
P( not red) = not red chips / total
= (blue + yellow) / total
= (10+4)/20
=14/20
=7/10
= 70%
Solve the following system using elimination:
{3 x - 4 y = -24 | (equation 1)
{x + y = -1 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x - 4 y = -24 | (equation 1)
{0 x+(7 y)/3 = 7 | (equation 2)
Multiply equation 2 by 3/7:
{3 x - 4 y = -24 | (equation 1)
{0 x+y = 3 | (equation 2)
Add 4 × (equation 2) to equation 1:
{3 x+0 y = -12 | (equation 1)
{0 x+y = 3 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -4 | (equation 1)
{0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = -4, y = 3
