Answer:

x = 0.59 to the nearest hundredth

Step-by-step explanation:

Look at the attached figure

∵ There are 5 small squares between every 2 numbers on the x-axis

∴ Each square represents 0.2

∵ There are 5 small squares between every 2 numbers on the y-axis

∴ Each square represents 0.2

∵ The point of intersection between the 2 graphs is nearest to

   the 3rd small square after the zero on the x-axis

∵ 0.2 × 3 = 0.6

∴ The x-coordinate of the point is approximately located at 0.59

∴ x = 0.59 to the nearest hundredth

Answer: 9 pounds of chocolate and 6 pounds of sugar candies

Let's define the variables:

C = pounds of chocolate candies used.

S = pounds of sugar candies used.

We know that he wants to make a total of 15lb, then:

C + S = 15

We also want that the price per pound to be equal to 5$.

This means that the price of the 15 pounds will be the same as the price of the un-mixed candies.

C*$7.00 + $2.00*S = $5.00*15

Then we have a system of equations:

C + S = 15

C*$7.00 + $2.00*S = $5.00*15

To solve this system, we need to start by isolating one of the variables, i will isolate C in the first equation:

C = 15 - S

now we can replace that in the other equation:

(15 - S)*$7.00 + $2.00*S = $5.00*15

Now we can solve this for S.

$105 - $5.00*S = $75

$105 - $75 = $5.00*S

$30 = $5.00*S

$30/$5 = S = 6

Then there are 6 pounds of sugar candy, and we can use the equation:

C + S = 15

C + 6 = 15

C = 15 - 6 = 9

There are 9 pounds of chocolate candy in the mix.

Step-by-step explanation:

By writing and solving a system of equations, we will see that the owner must use 6 lb of the chocolate candies and 9 lb of the sugar candies.

Let's define two variables:

Then, using the given information, we will have that:

x + y = 15

x*$7.00 + y*$2.00 = $5.00*15

If we isolate x in the first equation we get:

x = 15 - y

Now we can replace that in the second equation to get:

(15 - y)*$7.00 + y*$2.00 = $75

$105 - y*$5.00 = $75

$105 - $75  = y*$5.00

$30 = y*$5.00

$30/$5 = y = 6

So the owner must use 6 pounds of the chocolate candies, and the other 9 pounds of the sugar candies.

Step-by-step explanation: To find the area, we can use the F.O.I.L. method.

Notice that these two binomials are identical except

that one has a plus and one has a minus.

These types of binomials are called conjugates.

If you're asked to F.O.I.L. two conjugates, you can  

ignore the outer and inner products,

knowing they will cancel each other out.

So the answer to this problem comes from the product

of the first terms and the product of the last terms.

So our answer is 64x² - 25.

Answer:

There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.

Step-by-step explanation:

At first we need to find which integers between 27 and 53 are divisible by 6, which are, respectively:

[tex]A =\{30, 36, 42, 48\}[/tex]

All integers that have a remainder of 4 divided by 6 are found by summing 4 to each element of A, that is:

[tex]A' = \{34,40,46, 52\}[/tex]

There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.

Answer:

X = -5

Step-by-step explanation:

"Five less than a number is greater than twenty" represents the inequality (x - 5) > 20

Let a number is 'x'.

Now we will construct the inequality for the given statement.

"Five less than a number" means (x - 5)

And "five less than a number is greater than twenty" will be,

(x - 5) > 20

To simplify this inequality,

Add 5 on both the sides of the inequality,

(x - 5) + 5 > 20 + 5

x > 25

       Therefore, five less than a number is greater than twenty is an inequality, (x - 5) > 20

Answer:

Step-by-step explanation:

Step one:

weekly pay = $185

commission= 5.5% of sales= 0.055

let the sale be x

and his gross pay be represented by y

hence the expression for the total/gross pay is

y=0.055x+185

Step two:

Required is the gross pay y for x=3422

substituting we have

y=0.055*3422+185

y=188.21+185

y=373.21

Hence for a sale of $3,422 made his gross pay is $373.21

Step-by-step explanation:

A linear pair of angles is formed when two lines intersect.

Two angles are linear if they are adjacent angles formed by two intersecting lines.

Since the measure of a straight angle is 180°, a linear pair of angles must add up to 180°.

1. Two angles that add up to 180° are called supplementary.

2. The image shows a linear pair of angles. On the left side, the angle measures 2x, on the right side, the angle measures x+30. Since the sum is 180°:

2x + x + 30 = 180

Simplifying:

3x + 30 = 180

Subtracting 30:

3x = 180 - 30 = 150

Dividing by 3=

x = 150 / 3 = 50

x = 50°

3. The angle on the left is 2x = 100°

Angle measure on the left = 100°

4. The angle on the right is x+30 = 80°

Angle measure on the right = 80°
