5 x (12 - 6) divided by 2

Answer:

9

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 9 when x = - 3

9 = - 3k ( divide both sides by - 3 )

- 3 = k

y = - 3x ← equation of variation

When y = - 27 , then

- 27 = - 3x ( divide both sides by - 3 )

9 = x

Answer:

Step-by-step explanation:

X^2-3x=7/4 should first be rewritten in standard form, which here would be:

x^2 - 3x - 7/4 = 0.

1.  Identify the coefficient of the x term and take half of that number:

    -3/2

2. square this result:  (-3/2)^2 = 9/4

3.  add this last result, 9/4, between the -3x term and the -7/4 term, and then      subtract it as shown:

     x^2 - 3x + 9/4 - 9/4 - 7/4 = 0

4.  Rewriting the first 3 terms as the square of a binomial, we get:

    (x - 3/2)^2  -  16/4 = 0, or    (x - 3/2)^2  =  16/4

5.  Take the square root of both sides, obtaining:

     x - 3/2 = ±√4/2 or ±√2

6.  Write out the two roots:  x = 3/2 + √2

     and                                   x = 3/2 - √2

33.3% do not sing in the talent show.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of kids = 3

Number of kids who sang = 2

The number of kids who do not sing.

= 3 - 2

= 1

The percentage of kids who do not sing.

= 1/3 x 100

= 33.33%

Thus,

33.3% do not sing in the talent show.

Answer:

One equation you could use is 6(7 + 5) + 3.

Answer:

[tex]((3 * 7) - 6) * 5[/tex]

Step-by-step explanation:

For this problem, we will use trial and error.

It will take a while, but we can reduce the amount of guesses we have to make.

Looking at the problem, it is obvious that we will require multiplication at some point, as adding all the numbers together is nowhere near 75.

Let's start this problem by finding the prime factors of 75:

75 = [tex]25 * 3[/tex]

75 = [tex]5 * 5 * 3[/tex]

The prime factors of 75 are: [tex]5 * 5 * 3[/tex].

Our numbers are 7, 5, 6, and 3.

We already have a 5 and a 3, so we need to use 7 and 6 to get 5, and that's impossible, so this is a pass.

Next, we'll look at another factor, [tex]25 * 3[/tex].

We already have a 3, so we can ignore that. We need to use 7, 6, and 5 to get 25.

Here are some of the results:

[tex](5 * 6) - 7 = 23[/tex] (Nope)

[tex](7 * 5) - 6 = 29[/tex] (Nope)

[tex]6 + 5 + 7 = 18[/tex] (Nope)

There's more combinations, but the numbers are either too large or too small. This is a pass too.

Now, we'll try another factor, [tex]15 * 5[/tex].

We already have a 5, so let's ignore it and use 7, 6, and 3 to get 15.

[tex]7 + 6 + 3 = 16[/tex] (Nope)

[tex](6 * 3) - 7 = 11[/tex] (Nope)

[tex](3 * 7) - 6 = 15[/tex] (Yep)

So our expression to make 15 is [tex](3 * 7) - 6[/tex]. Then we multiply the whole thing by 5. Thus our expression is:

[tex]((3 * 7) - 6) * 5[/tex]

Let's check our answer:

[tex]((3 * 7) - 6) * 5[/tex]

[tex](21 - 6) * 5[/tex]

[tex]15 * 5[/tex]

[tex]75[/tex]

The expression gives us 75, which is what we want, so our answer is correct.

Answer:

1 d know

Step-by-step explanation:

the correct use of the distance formula is the equation :

√((27 - 12)² + (y₂ - 15)²).

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given a diagram of a line for that distance, the line needs to find

the general formula for distance

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Thus, for the given coordinates formula for distance

d = √((27 - 12)² + (y₂ - 15)²)

therefore, the equation √((27 - 12)² + (y₂ - 15)²) is the correct use of the distance formula.

Answer:

the dimensions would b 10 10 and 10

Answer:

The set of values are described below:

[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

Step-by-step explanation:

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]OJ \parallel RS[/tex] and [tex]OP \parallel RM[/tex]. By Alternate Internal Angles, we find that [tex]\angle R \cong \angle O[/tex]. In addition, the sum of internal angles in triangles equals 180°. Then, we have the following system of linear equations:

[tex]m\angle R + m\angle M + m\angle S = 180^{\circ}[/tex] (1)

[tex]m \angle O + m \angle P + m\angle J = 180^{\circ}[/tex] (2)

[tex]m\angle S = 65^{\circ}[/tex] (3)

[tex]m \angle M = m\angle P = 90^{\circ}[/tex] (4)

The solution of this system is [tex]m\angle R = 25^{\circ}[/tex], [tex]m \angle O = 25^{\circ}[/tex] and [tex]m \angle J = 65^{\circ}[/tex].

Lastly, the remaining sides are found by definition of congruence

Segment RS

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline {RS} \cong \overline {OJ}[/tex]. Hence, [tex]RS = 25\,cm[/tex]

Segment JP

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline{SM} \cong \overline {JP}[/tex]. Hence, [tex]JP = 10\,cm[/tex]

The set of values are described below:

[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

Answer:

James will need to buy 3 boxes of crackers for the party.

Step-by-step explanation:

remember: 16oz=1 pound

If James needs 3 pounds of crackers, and each box is 20oz, that means each box is a little over 1 pound. (1.25 pounds to be exact). So, we know that he needs to buy 3 boxes of crackers. This is because 20×3=60 ounces which is 3.75 pounds. Meaning, 3 boxes is the correct answer since we can't cut a box in half.

hope this helps!

Answer:

3 boxes

Step-by-step explanation:

First, calculate how many oz in one pound: 16 oz = 1 pound

Now we know that our situation includes smaller to larger.

Since we are going smaller to larger, we need to multiply.

You should multiply 20 x 3 = 60 oz from what I learned.

60 oz = 3.75 pounds. In another situation you would round, but who cares about rounding. Your answer is 99.100% correct

If this was wrong, I'm sorry. The way I learned is smaller to larger: multiply; larger to smaller: divide.

Hopefully, this was right!

Over means that 40 should be excluded

C) ASA

Step-by-step explanation:

angles are indicated equal and they share the common diagonal between those angles, so ASA

The given two triangles are congruent due to the ASA postulate, which is the correct answer that would be an option (C).

Two triangles are said to be congruent if their corresponding sides and angles are equal.

The given triangles are given in the figure.

We can see that there are two angles that are the same and one side is the same.

According to ASA, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.

So, we conclude that the given two triangles are congruent.

Hence, the given two triangles are congruent due to the ASA postulate.
