If x=students, the equation would be x=12 (x is less than of equal to twelve). I don’t know what you mean by constraints; perhaps if you explain more, I could help?

Geoff wants to make a 200 ml of 6% alcohol solution mixing a quantity of a 3% alcohol solution with a 8% alcohol solution. What
Marina86 [1]

Answer:

Volume of 3% alcohol = 80 ml

Volume of 8% alcohol = 120 ml

Step-by-step explanation:

Final volume of 6% alcohol solution = 200 ml

Let the volume of 3% alcohol volume = a ml

Therefore, volume of 8% alcohol = (200 - a) ml

Equation for the given situation will be,

3a + 8(200 - a) = 6×200

3a + 1600 - 8a = 1200

1600 - 5a = 1200

5a = 400

a = 80 ml

Therefore, volume of 3% alcohol to be used = 80 ml

And volume of 8% alcohol to be used = (200 - 80) = 120 ml

Marsha has budgeted no more than $3,000 on centerpieces for the tables at the reception, which inequality represents all possibl
Black_prince [1.1K]

Answer:

x+y\leq 3000

Step-by-step explanation:

Given : Marsha has budgeted no more than $3,000 on centerpieces for the tables

x denotes the number of Guest Tables Lily Arrangements

y denotes the number of Family Table Rose Arrangements

To Find: Which inequality represents all possible combinations of x,  and y,  that Marsha can buy for no more than $3,000?

Solution :

Since there are x number of Guest Tables Lily Arrangements.

And there are y  number of Family Table Rose Arrangements

Since she cannot spend more than 3000 on centerpieces .

So, the inequality becomes:

x+y\leq 3000

Hence inequality represents all possible combinations of x and y that Marsha can buy for no more than $3,000:

x+y\leq 3000
