a - b= 2

Step-by-step explanation:

expanding the brackets

we have 15x^2+13x+2

a= 15 b= 13

thus, a-b =15-13

=2

The value of a - b if,  (3x + 2) (5x + 1) = ax² + bx + 2 is 2 i.e a - b = 2.

At least two numbers or variables, one or more arithmetic operations, and a statement are all required components of a mathematical expression. The term "expression" or "mathematical expression" refers to a finite collection of symbols that are well-formed in line with context-dependent criteria.

Given:

(3x + 2) (5x + 1) = ax² + bx + 2

Write the left term of the equation in the format of the right term,

3x (5x + 1) + 2(5x + 1)

15x² + 3x + 10x + 2

15x² + 13x + 2

Compare the above equation to ax² + bx + 2,

a = 15 and b = 13

Calculate the value of a - b as shown below,

a - b = 15 - 13

a - b = 2

Answer: Each piece would be 3/4 feet long

Step-by-step explanation:

If the piece of  lumber is 2 1/4 ft long, and it is cut into 3 pieces then divide

2 1/4 by 3 to find out how long each piece of cut wood would be.

2 1/4  is the same as 9/4

[tex]\frac{9}{4} / \frac{3}{1}[/tex] = 9/12  which also simplifies to  3/4

Cost of the strawberry will be $0.31 per ounce.

   Given in the question,

We can write the cost as [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}[/tex].

Since, 1 pound = 16 ounces

To convert the cost of the strawberry in dollars per ounce, multiply the price by the conversion factor [tex]\frac{1\text{ Pound}}{16\text{ Ounces}}[/tex].

So the cost of strawberry = [tex]\frac{4.96\text{ Dollars}}{1\text{Pound}}\times \frac{1\text{ Pound}}{16\text{ Ounces}}=0.31\text{ Dollars per ounce}[/tex]

    Therefore, cost of the strawberry will be $0.31 per ounce.

Answer:

Step-by-step explanation:

Yes, you can form a kite.  The top two would be 2 units, and the bottom two would be 4 units.  It would still have two of each, just like the rectangle, but would be a different quadrilateral.  

Alternately, you could turn the rectangle into a parallelogram by leaning it.  Rectangles have 90 degree angles, so it wouldn't be a rectangle anymore.

[tex]\huge\boxed{\sf x = -7}[/tex]

Step-by-step explanation:

Let the number be x

So,

=> The sum of number and 15 is x + 15

=> Three times will be 3(x+15)

Given that it equals 24

So, the given condition is:

3(x+15) = 24

Resolving Parenthesis

3x + 45 = 24

Subtracting 45 to both sides

3x = 24 - 45

3x = -21

Dividing both sides by 3

x = -7

Answer: 1 hand = 0.22... cubits.

Step-by-step explanation:

We want to write the relation between hands and cubits.

We know that there are 9 hands in 2 cubits.

So we can write:

9 hands  = 2 cubits.

Now, we want to have an unit in the left side (so we can see how many cubits are equal to exactly one hand).

Then we can divide by 9 in both sides of the equality.

(9 hands)/9 = (2 cubits)/9

1 hand = 0.22... cubits.

Answer:

22.5 hands = 3 paces

If a beverage is made by mixing 3 parts of water with 5 parts of fruit juice then 3/5 fraction of water is mixed with 1 part of fruit juice.

Given that, a beverage is made by mixing 3 parts of water with 5 parts of fruit juice.

Fraction is a combination of numerator and denominator. The number above the division sign is known as numerator and the numerator below the division side is known as denominator.

We have been given that to make a beverage 3 parts of water with 5 parts of fruit juice and we are required to find the fraction of water mixed with 1 part of fruit juice.

Water mixed with 1 part of fruit juice

= Water mixed with 5 parts of fruit juice/5

= 3/5

Hence, if a beverage is made by mixing 3 parts of water with 5 parts of fruit juice then 3/5 fraction of water is mixed with 1 part of fruit juice.

The perimeter of the triangle is 36 units.

The distance between two points A(x₁, y₁) and B(x₂, y₂) is given by:

The coordinate of the triangle is A(0, 0), B(10, 0) and C(5, 12). Hence:

AB = 10 units

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

Answer:

50

Step-by-step explanation:

Since M is the midpoint of XY, this means that XM and MY must be equivalent from the definition of midpoint.

So:

[tex]XM=MY[/tex]

The entire length of the segment (XY) is:

[tex]XY=XM+MY[/tex]

We know that XM is equivalent to MY. Substitute MY for XM:

[tex]XY=MY+MY[/tex]

Combine like terms;

[tex]XY=2MY[/tex]

We are told that YM (or MY) is 25. So:

[tex]XY=2(25)[/tex]

Multiply:

[tex]XY=50[/tex]

So, the length of XY is 50.

And we're done!

Answer:

B

Step-by-step explanation:

sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] → B

The equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]

From the question, we are to determine which equation should one solve to find x

Considering the right triangle in the diagram,

Opposite = x

Adjacent = 9

Hypotenuse = 10  

By SOH CAH TOA

We have that

[tex]sin\theta = \frac{opposite}{hypotenuse}[/tex]

Where θ is the angle

Then, we can write that

[tex]sin\ 26^\circ =\frac{x}{10}[/tex]

This is the equation that should be solved in order to find x

Hence, the equation that should be solved in order to find x is [tex]sin\ 26^\circ =\frac{x}{10}[/tex]. The correct option is C. [tex]sin\ 26^\circ =\frac{x}{10}[/tex]
