Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.

Hence:

x + y = 7                    (1)

Also, John wants to spend at most $9.00 on cat food each week. Hence:

1.5x + 0.75y ≤ 9       (2)

The list of possible points after solving graphically are:

(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:

(5, 2) i.e. 5 wet food and 2 dry food

anzhelika [568]

Answer:

N*B*x/100

Step-by-step explanation:

To determine an equation of the total number of dollars, it is necessary to review the variables that influence

The most important, N that would be the number of shares of A.

The other variable is B, since it would be the price of the shares that were purchased.

Lastly, we have x, since he originally had was A's shares, therefore his increase occurred in A's shares, that is, x.

Therefore, the equation would be:

N * B * x / 100

It is divided by 100 since x is a percentage.

Can anybody help me?
lakkis [162]

You know that 6x+3 equals 45 because the two sides are equal. So you first put the equation 6x+3=45. Then you use the subtraction property of equality and subtract 3 from both sides. This gives you 6x=42. Then you divide 6 from both sides to get you final answer, x=7
