Ronald is making hats and scarves for charity. He has enough yarn to make 5 hats and 8 scarves. Takes him 12 hrs to knit a hat,

kari74 [83]

Constraints are simply the subjects of an objective function.

The inequality that represents the constraint is: $12x + 6y \le 20$

Represent the number of hats with x, and the number of scarves with y.

From the question, we have:

He spends 12 hours to knit a hat
He spends 6 hours to knit a scarf

So, the equation of the total time spent is:

$Time = 12x + 6y$

This time spent is not more than 20 hours.

So, the inequality is

$12x + 6y \le 20$

Hence, the inequality that represents the constraint is: $12x + 6y \le 20$

Dilly is 7 years younger than Dally. In 4 years time she will be half Dally’s age. What is the sum of their ages now?

Step2247 [10]

Answer:

<u>The sum of their ages now is 13</u>

Step-by-step explanation:

Dally's age = x

Dilly's age = x - 7

In 4 years time Dilly will be half Dally’s age, therefore:

Dilly's age plus four equals to half of Dally’s age plus four,

replacing with the values and variables we know:

x - 7 + 4 = (x + 4) /2

x - 3 = (x + 4) /2

2x - 6 = x + 4 (Multiplying by 2 at both sides)

2x - x = 4 + 6 (Like terms)

x = 10 ⇒ x - 7 = 3

<u>The sum of their ages now is 13 (10 + 3)</u>

What is the solution of x-1/1-x < 0?

kykrilka [37]

Option C is correct option.

Step-by-step explanation:

We need to find the solution of $\frac{x-1}{1-x}$

The given inequality becomes undefined when x = 1 because the denomiator is: 1-x and if x = 1 then it becomes 1-1 = 0 and anything divided by zero is undefined.

So, all values other than 1 are included in the solution of the given inequality.

So, solution is: x<1 or x>1 but x≠1

So, Option C is correct because all numbers are included in number line except 1. An unfilled circle on 1 shows that it is not included in the solution. Rest of numbers are included.

Option C is correct option.

Problems with Equations: Mastery Test

GaryK [48]

Step-by-step explanation:

The answer is 8

Because you have to put each value of x given in the equation 3x = 24

So when you put the value 8

3(8) = 24

24 = 24
