Say we have ratios and i have to determine which one does not belong 12 : 18 2 to 3 6/9 18 : 21
so the ratio that does not belong is?

Solve 2x+y=3 x+y=5 in substitution method

Problem situation: caren is making rice and beans. she can spend no more than $10 on ingredients. she buys one bag of rice for $4.99. beans cost $0.74 per pound. how many pounds of beans, x, can she buy? inequality that represents this situation: 10≥4.99+0.74x drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.

Plzzz answer both questions and i will give you 100 points
