Given: ⅓ (18x + 27) = 81 Prove: x = 12
Answers
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.

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.
What is an Equilateral Triangle?An equilateral triangle is a triangle whose three sides have the same length, and all three interior angles are equal to 60 degrees each.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.

For what values of t can 2x^2+tx+10 be written as the product of two binomials?
Answers
The value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.
What is binomial?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.

Answers
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°.

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
Answers
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

A rectangle has dimensions 8 1/5 in by 13 in. A diagonal of the rectangle forms two matching right triangles. What is the area of one of the triangles.
The area of one of the triangle is ____ in.
Answers
Answer:
53.3 in^2
Step-by-step explanation:
Given data
Base B= 13in
Height H= 8 1/5 in= 41/5in
The expression for the area of a triangle is
Area= 1/2 Base * Height
Substitute
Area= 1/2* 13* 41/5
Area= 6.5*41/5
Area= 266.5/5
Area= 53.3 in^2
Hence the area is 53.3 in^2
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,

Answers
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.
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters, and (6q – 9) centimeters.
