The inequality that represents the possible ways nina can eat 12 or more grams of protein is 2x + 3y ≥ 12
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Let x be the number of cheese squares that she eats and y is the number of turkey slices that she eats. If nina can eat 12 or more grams of protein, hence:
2x + 3y ≥ 12
The inequality that represents the possible ways nina can eat 12 or more grams of protein is 2x + 3y ≥ 12

There are no real solutions to solve Z. If there may be a typo or something, there are no solutions.
Answer:
Step-by-step explanation:
Answer:
33 1/3 L of the 40% solution, 16 2/3 L of the 25% solution
Step-by-step explanation:
Set up two equations...
Let x represent the number of Liters of the 40% solution
Let y represent the number of Liters of the 25% solution
We need 50 liters total, so
x + y = 50
and we need the 50 L to be 35% solution, so
0.4x = 0.25y = 0.35(50)
Solve the first equation for one variable...
x = 50 - y (subtract y from both sides in equation 1)
Now substitute that value into the second equation...
0.4(50 - y) + 0.25y = 17.5 (x becomes 50 - y, 0.35(50) = 17.5)
Now solve for y...
20 - 0.4y + 0.25y = 17.5
-0.15y = -2.5
y = 16.66666667
y = 16 2/3 L
So we need to plug that into the first equation to find 'x'
x + 16 2/3 = 50
x = 50 - 16 2/3
x = 33 1/3
