The equation that have same solution to 3x-12=24 is 4x - 30 = 18.
What is an equation?A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.
The equation given is illustrated as:
3x - 12 = 24
Collect like terms
3x = 24 + 12
3x = 36
Divide through by 3.
3x / 3 = 36 / 3
x = 12
In this case, 4x - 30 = 18 will be:
4x - 30 = 18.
Collect like terms
4x = 18 + 30.
4x = 48
Divide
x = 48/4
x = 12

what the meaning of geometric sequence?
Answer:
What is the meaning of geometric sequence?
Step-by-step explanation:
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is. a n= a 1 r n – 1. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.
Answer:
Below.
Step-by-step explanation:
It is a sequence of numbers with a common ratio. That is, each term after the first is obtained by multiplying the previous one by the common ratio.
Examples:
2, 6, 18, 54 ... is a geometrics sequence with common ratio 3.
1, 1/2, 1/4, 1/8 ... has a common ratio of 1/2.
-1, 1, -1, 1, -1 ... has a common ratio of -1.
The nth term of a geometric sequence is given by
a r^(n-1) where a = first term and r = common ratio.

2 times 61= 122. Add 24 and you get 146. We can know this is correct because we are given the other angle and it's degrees, whch is also 146 degrees. Therefore, the answer is A, 61.
what is i (5+5) vey (5-5) u
The sentence that represents the expression (5 + 5)ve y(5-5) u is:
love you.
How to translate the expression to a sentence?The expression is given as follows:
(5 + 5)ve y(5-5)u
There are two operations in the expression, as follows:
5 + 5 = 10. (addition of 5 and 5 = multiplication of 5 by 2).5 - 5 = 0. (subtraction of 5 and 5).Then the expression, with the numbers, is given as follows:
10ve y0o.
The number 10 can be interpreted as the two letters lo, as l and 1 are very similar symbols, as are 0 and o, then the updated expression is:
love y0u.
The same is applied to the final zero, as 0 and o are very similar symbols, hence the sentence that represents the expression is:

The number 2n and 2n + 2 will always are 2 consecutive even numbers.
What is termed as the consecutive even numbers?Consecutive numbers are numbers that obey one another in a regular adding up order or pattern. They are written in a series with a fixed difference here between numbers and no numbers skipped in between. We know that even numbers end in 0, 2, 4, 6, and 8. Consider a set of even numbers ranging from 2 to 12 but rather write those in ascending order. When written from smallest to largest, the numbers are organized as 2, 4, 6, 8, 10, 12. The difference between any former leader pair is 2, as we can see. As a result, these numbers comprise the collection of consecutive even numbers.From the given option in the question;

It costs $2.50 to rent bowling shoes. Each game $2.25. Write an equation that represents the cost, c, to bowl after g, number of games
In linear equation, $9.25, you can bowl a maximum of 3 games.
What in mathematics is a linear equation?
An x-y linear relationship, or two variables in which the value of one of them (often y) relies on the value of the other one, is what is known as a linear equation in two variables (usually x). The dependent variable in this scenario is y since it depends on the independent variable, x.If it costs $2.50 to rent bowling shows and each game costs $2.25, then the total cost of playing x bowling games can be represented as
C = 2.50 + 2.50x
If you have a total of $9.25, then
9.25 = 2.50 + 2.25x
Subtracting 2.50 from both sides of the equation, we get
9.25 - 2.50 = 2.50 + 2.25x - 2.25
6.75 = 2.25x
Dividing both sides of the equation by 2.25, we get
6.75/2.25 = 2.25x/2.25
x = 3
Therefore, with $9.25, you can bowl a maximum of 3 games.

Angle XBC is a corresponding angle to angle AXY.
The value of angle BXC is 30 degrees.
How to find measure of angles?When parallel lines are cut by a transversal line, angle relationships are formed such as alternate angles, corresponding angles, linear angles, vertically opposite angles etc.
Therefore, XY and BD are parallel lines and are cut by the transversal line AB and XC.
XBC forms an isosceles triangle.
∠AXY = 75 degrees.
∠XBC is a corresponding angle to ∠AXY.
Corresponding angles are congruent.
Therefore,
∠AXY = ∠XBC
Let's find the angle BXC.
The sum of angle in a triangle is 180 degrees.
The triangle BXC is an isosceles triangle. An isosceles triangle has base angles equal to each other.
Hence,
75 + 75 + ∠BXC = 180°
∠BXC = 180 - 150

Take a as a factor.
a( x² + ( b / a )x + ( c / a ) );
Add and subtract the square of ( 1 / 2 ) of ( b / a ). This is called completing the square because it forms a perfect square trinomial.
a( x² + ( b / a )x + ( b / 2a )² - ( b / 2a )² + ( c / a ) );
Factorise the trinomial.
a( ( x + ( b / 2a ) )² - ( b / 2a )² + ( c / a ) );
Use the distributive property of multiplication.
a( x + ( b / 2a )² + a( ( c / a ) - ( b / 2a )² );
a( x + ( b / 2a )² + a( ( c / a ) - ( b² / 4a² ) );
Simplify the fractions.
a( x + ( b / 2a )² + c - ( b² / 4a );
SolutionSubstitute the values.
- 16( t - ( - 28 / 2( - 16 ) )² + 7 - ( ( 28 )² / 4( - 16 ) );
Time is the x-axis so we need to solve for the axis of symmetry.
h = ( - 28 / 2( - 16 ) );
h = ( - 28 / - 32 );
Simplify the fraction.
h = ( 7 / 8 );
Maximum height is the parabola's y of the vertex.
k = 7 - ( ( 28 )² / 4( - 16 ) );
k = 7 - ( ( 28 )( 28 ) / - 64 );
k = 7 - ( 784 / - 64 );
k = 7 - ( - 49 / 4 );
k = ( 28 / 4 ) + ( 49 / 4 );
k = 77 / 4;
