Hihi! I really need help with this one and I need to show just a bit of work for it- if it's right I'll give brainliest :D ( It's called brainliest- right? )

Answer:

i think it is B

Step-by-step explanation:

If 10x = qx for all values of x, then q must be equal to 10. so, the answer is (D)

Two or more expressions with an Equal sign is called as Equation.

To have infinitely many solutions, both sides of the equation should be equal regardless of the value of x.

This means that the left side of the equation should simplify to a constant, and the right side of the equation should also simplify to the same constant.

Starting with the left side of the equation:

-8x + 1/4(20x - 12) = qx - 13x - 3

-8x + 5x - 3 = qx - 13x - 3 (distributing 1/4 to (20x - 12))

-3x - 3 = qx - 13x - 3 (combining like terms)

-3x = qx - 13x (subtracting 3 from both sides)

Now, let's simplify the right side of the equation:

-3x = qx - 13x

-3x + 13x = qx (adding 13x to both sides)

10x = qx

Hence, If 10x = qx for all values of x, then q must be equal to 10. so, the answer is (D)

Answer:

He would save $455.5

You would multiply 13 by 16 to get the total area of the deck.

Then you would multiply 208 times 21.09

Then you would multiply 208 by 18.90

You would get two numbers: 4386. 72 and 3931.2

You subtract the two numbers and you get 455. 52

Step-by-step explanation:

Answer:

455.52

Step-by-step explanation:

16x13=208

Cedar:

208x21.09= 4,386.72

Pressure-treated:

208x18.90= 3,931.2

Difference

4,386.72-3,931.2= 455.52

Answer:

95 over 2

because if it is 47 you double that since the denominator is 2 then you add the numerator and now you have your answer.

Answer:

12 1/2 mins

Step-by-step explanation:

If the teacher has 47 1/2 minutes left, and there are 60 minutes in an hour, all you have to do is 60-47.5 which is 12.5. To change this into a mixed number, we know 5 is half of 10, so it is 12 1/2 minutes. Hope this helped.

Answer: n>1.5

( n2 here means 2×n not n² )

Step-by-step explanation:

5 + 2n > 8

Subtract 5 from both sides

5 -5 + 2n > 8 -5

2n > 3. Divide both sides by 2

2n/2 > 3/2

n = 1.5

Answer:

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.

Answer:

x∠ = 32

Step-by-step explanation:

since this is a right triangle we can tell that one angle is a right angle (that is, a 90-degree angle)

and since the outsider angle is 122 degrees the sum between the inside one and the outside one must be 180 which means it is 180 - 122 = 58

so we know that the right angle is 90 degrees, the other one is 58 and the sum of angles in a triangle is 180, x must equals 32

180 - 90 - 58

Answer:

after 5 trash cans the waste away would be cheaper

Step-by-step explanation:

28+8x

12x

you would plug in numbers for x until one of them is cheaper in this case waste away is cheaper by $8 after 5 trash cans

There are fewer than six trash cans, so it is less expensive for a customer to choose Waste Away as their trash service.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let x be the number of trash cans.

The cost for Trash Management is 25 + 8x, and the cost for Waste Away is 12x.

To determine the number of trash cans for which Waste Away is less expensive, we need to find the number of trash cans such that the cost for Waste Away is less than the cost for Trash Management, which can be expressed as 12x < 25 + 8x.

Solving for x, we get 12x - 8x < 25, which simplifies to 4x < 25.

Dividing both sides by 4, we get x < 25/4.

Therefore, it is less expensive for a customer to use Waste Away as their trash service if they have fewer than 25/4 = 6.25 trash cans.

Since the number of trash cans must be an integer, the inequality can be rewritten as x < 6.
