Answer:

Firstly, rewrite the equation:

⅓ (18 + 27) = 81

Substitute x for the given number of it's supposed equivalent.

In this case x = 12.

⅓ (18(12) + 27) = 81

Solve using PEMDAS and simplify what is in the parenthesis first. Then, multiply.

(18 x 12) + 27 = 243

Now, solving using PEMDAS, multiply the total of what you got that was originally in the parenthesis by ⅓ .

⅓ (243) = 81

When you multiple these number they are equivalent to 81.

81 = 81

Since the equation given, when substituted x for 12, is equivalent to 81, this proves that substituting x for 12 makes this equation true.

Answer:

68°

Step-by-step explanation:

The sum of all internal angles of a circle always total 360°.

So, we can add the three angles (ADB, BDC, ADC) and equate them to 360°.

90 + (2x+1) + (2x-3) = 360

90 + 4x -2 = 360

4x - 2 = 360 - 90

4x - 2 = 270

4x = 272

x = 272/4

x = 68°

From here, you can find any of the two unknown angles by simply plugging in x = 68°.

Answer:

Step-by-step explanation:

For these, you can find the appropriate formula by looking at the ratio of the first two terms. That will be the number in parentheses in the explicit formula. If there is no match, it is not geometric.

The value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.

A binomial expression is an expression that has two terms.

In order to get the value of t for which the given expression 2x²+tx+10 will be a product of two binomial. We need to find a number(A) that is when broken into two other numbers(B and C), the sum of these numbers(B and C) is the number itself(A). Also, the product of the two numbers is equal to the product of the rest two terms of the expression(2 and 10).

Therefore, the number that fulfills this condition is 9. Let's check by substituting the value of t as 9.

[tex]2x^2+tx+10\\\\= 2x^2+9x+10 \\\\= 2x^2+5x+4x+10\\\\ = x(2x + 5)+2(2x+5)\\\\= (x+2)(2x+5)[/tex]

Hence, the value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.

Given:

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,

and (6q – 9) centimeters.

To find:

The expression that represents the perimeter, in centimeters, of the triangle.

Solution:

We know that, perimeter of a triangle is the sum of its all sides.

[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]

Combining like terms, we get

[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]

[tex]Perimeter=(13p)+6q+(-18)[/tex]

[tex]Perimeter=13p+6q-18[/tex]

Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.

Answer:

15 ounces

Step-by-step explanation:

Each box contains 4 toys; a 5-ounce truck and three bags of marbles. The bags of marbles are all identical. How much does each bag of marbles weigh?

We need the total weight of the box. This is not given in the question, hence:

Let us assume

The total weight of the = 50 ounces

A 5-ounce truck and three bags of marbles.

Let the weight of one bag of marble = x

Hence,

5 ounces +3x = 50 ounces

3x = 50 ounces - 5 ounces

3x = 45 ounces

x = 45 ounces/3

x = 15 ounces

Therefore, the weight of each bag of marble is 15 ounces

Answer:

x = 4 units

Step-by-step explanation:

2/z = z/6

z² = 12

z = 2√3

using the Pythagorean theorem:

x² = 12 + 2²

x² = 16

x = 4

Based on the definition of an equilateral triangle, the value of x is: B. 4 units.

If triangle MRN is created when an equilateral triangle is folded in half, therefore:

x = 1/2 of (NM)

x = 1/2(6 + 2)

x = 1/2(8)

x = 4 units

Therefore, based on the definition of an equilateral triangle, the value of x is: B. 4 units.

Answer:

IS THERE A PICTURE SO WE CAN SEE

No, because he kept adding to both sides rather than distributing 2 from x and 9 from the start

Answer:

I don't agree with his method because he should've used the distribute method for the first step. For step 2, he would've needed to add 18 on both sides. Step 3 would be for him to divide both sides by 2, not subtract 2.

Step-by-step explanation:

2(x - 9) = 10

step one: distribute

⇒ 2x - 18 = 10

step two: add 18 on both sides and then simplify

⇒ 2x - 18 + 18 = 10 + 18

⇒ 2x = 28

step three: divide both sides by 2

⇒ [tex]\frac{2x}{2} = \frac{28}{2}[/tex]

⇒ x = 14

Answer:

The answers is x=3

Step-by-step explanation:

Divide both sides by the numeric factor on the left side then solve.
