Answer:
Unit rate is 3 ounce of water per ounce of mix
Step-by-step explanation:
you combine 12 ounces of mix with 36 ounces of water.
12 ounces of mix for 36 ounces of water
For unit we need to find the ounces of water for 1 ounce of mix
12 ounces of mix for 36 ounces of water
so 1 ounces of mix for 36 / 12 = 3 ounces of water
3 ounces of water for 1 ounce of mix
Hence, 3 ounces of water per ounce of juice
0.87 is 87/100 does 87 and 100 have any common factors ? Nope so it's 87/100
Solve the following system:
{-3 + 2 x + y = 0 | (equation 1)
{-1 + x + y = 0 | (equation 2)
Express the system in standard form:
{2 x + y = 3 | (equation 1)
{x + y = 1 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + y = 3 | (equation 1)
{0 x+y/2 = (-1)/2 | (equation 2)
Multiply equation 2 by 2:
{2 x + y = 3 | (equation 1)
{0 x+y = -1 | (equation 2)
Subtract equation 2 from equation 1:
{2 x+0 y = 4 | (equation 1)
{0 x+y = -1 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 2 | (equation 1)
{0 x+y = -1 | (equation 2)
Collect results:
Answer: {x =2 , y = -1
