describe all numbers x that are at a distance 2 from the number 6

Answer:

8(x + 6) = 144

Step-by-step explanation:

We can start building this equation by making everything equal to 144 since the problem is representing the total number of apples:

? = 144

Next, we don't know how many apples are in each basket, so we can represent it with a variable, x.

Since 6 apples are added to each basket we will simply add 6 to the "x" amount of apples in each basket:

x + 6 = 144

Lastly, according to the scenario, we have 8 baskets, each holding "x" amount of apples plus the extra 6 that was added, so it will be multiplied:

8(x + 6) = 144

Shana bought  5 bags of popcorn and 2 bottles of soda.

What is an equation?

An equation is consist of two expressions. At least one of the expression contain a variable.

Given that, the cost unit bottle of soda is $3.

The cost of unit bag popcorn is $4.

Assume that she bought s number of soda bottle and p number of bags of popcorn.

Then the cost of s number of soda bottle is $3s.

The cost of p number of bags of popcorn $4p.

She spent $26 in total.

Therefore

3s + 4p = 26.....(i)

She bought 7 things from the shop.

Therefore,

s + p =7 .....(ii)

Solve equation (i) and (ii) by using elimination method:

Multiply equation (ii) by 3 and subtract it from (i)

3s + 4p = 26.

3s + 3p =21

Answer:

x=4.321928

Here’s your explanation

Let's solve your equation step-by-step.

2^x=20

Solve Exponent.

2^x=20

log(2^x)=log(20) (Take log of both sides)

x*(log(2))=log(20)
x=log(20)

log(2)

Then you get your answer x=4.321928

Step-by-step explanation:

Take the log of both sides:

log2(2^x) = log2(20)

xlog2(2) = log2(20)

x(1) = log2(20)

x = log2(20) ≈ 4.322

The area of trapezoid with sides 125ft and 81ft with height 75ft is: 7,725ft².

Area of a trapezoid,

A = 1/2 x (b1 x b2)h

Here given,

b1 = 125ft

b2 = 81ft

The area of trapezoid is 7725 ft²

What is a trapezoid?

In American and Canadian English, a quadrilateral with at least one pair of parallel sides is referred to as a trapezoid. It is referred to as a trapezium in British and other varieties of English.

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases. Unlike the specific situations below, a scalene trapezoid is a trapezoid that lacks equal-sized sides.

Given, the expression for the area a is given as

a = [(b₁ + b₂)/2]*h

where b₁ = 125ft, b₂ = 81ft, h = 75ft.

Substituting these values in the above area expression, we get,

a = [(125+81)/2]*75

a = 103*75

a = 7725 ft²

Thus, the area of trapezoid is 7725 ft²

The coordinate of the reflection about the line y = 9 is thus (7, 4)

Reflection is a transformation in which an object is flipped over a line.

We know that to reflect W(-7, 4) over the line y = 9, the distance of the point W and its reflection from the line y = 9 must be the same.

The distance of point W(-7, 4) from the line y = 9 is d = 9 - (- 7) = 9 + 7 = 15

So, the x - coordinate of the reflection from the line y = 9 is x = 15 - 9 = 7

Since the y - coordinate of the point W, does not change, the coordinate of the reflection about the line y = 9 is thus (7, 4)

So,  the coordinate of the reflection about the line y = 9 is thus (7, 4)

The  missing side length in the given right triangle is d) 23.6cm if the other two sides lengths are 14cm and 19cm respectively. So, correct option is d.

We know very well that if a triangle is a right angled it means that  Pythagorean Theorem is applicable on it.

Pythagorean Theorem states that if a triangle is right angled then the sum of square of two sides which are originating from that angle which is 90 degree is equal to square of third side.

In other words,a²+b²=c² where a and b are two sides originating from 90 degree angle and c is the third side which is opposite of the 90 degree angle.

Now, we have a=14 and b=19cm,we need to find value of c.

So, putting the values, we get

=>14² + 19² =c²

=>c²=361+196

=>c² = 557

=>c=√557

The smallest possible composite, positive, integer x and y such that x/y=5 are x=20, y=4.

The result of multiplying two smaller positive integers is a positive integer known as a composite number. It is, in other words, an integer that is positive and has at least one divisor besides itself and 1. The composite numbers are exactly the numbers that are not prime and not a unit, since every positive integer is either composite, prime, or the number 1.

Because it is the result of the two smaller integers 2 and 7, for instance, the number 14 is a composite number. The integers 2 and 3 are also not composite numbers because they can only be divided by one another and themselves.

The system of equations has infinite solutions, both equations represent the same line.

Here we have the following system of equations:

-3x+6y=12

2y=x+4

And we want to solve this by substitution, first, we can rewrite the first equation as:

-3x + 3*(2y) = 12

Now we can substitute the second equation 2y = x + 4 in the parenthesis, we will get:

-3x + 3*(x + 4) = 12

Now we can solve this for x.

-3x + 3x + 12 = 12

A cube (plural "cubes") is a solid with marks on each face. Since the faces are usually all of the same shape, the dual of the Platonic solids and the Archimedean solids is a natural choice. You can "roll" a die by throwing it in the air and letting it rest on one of its faces.
