Answer:
x = 18
Step-by-step explanation:
The line joining 2 midpoints of the non parallel sides of a trapezoid is 1/2 the sum of the two parallel lines.
Put in much simpler language XY = 1/2 (BC + AD)
4x - 2 = 1/2 (6x + 1 + x) Combine the right
4x - 2 = 1/2 (7x + 1) Multiply by 2
8x - 4 = 7x + 1 Add 4 to both sides
8x = 7x + 5 Subtract 7x
x = 5
But what you want is the length of XY
XY = 4x - 2 = 4*5 - 2 = 18
Sorry I noticed too late that I used x for s. The answer would still be 18.

Answer:
n = 1.92
Step-by-step explanation:
Multiply both sides of the equation by 3.2
[tex]3.2*\frac{2}{3.2} =3.2*\frac{9.6}{16}[/tex]

Find the sum of the first 22 terms of the arithmetic sequence, the first term is - 2 and the common difference is -5.
Answers
Answer:
The sum of the first 22 terms of the sequence is -1199.
Step-by-step explanation:
Arithmetic sequence:
The general term of a arithmetic sequence is given by:
[tex]A_n = a_1 + (n-1)r[/tex]
In which [tex]a_1[/tex] is the first term and r is the common difference.
The sum of the first n terms of a arithmetic sequence is given by:
[tex]S_n = \frac{n(a_1+a_n)}{2}[/tex]
First term is - 2 and the common difference is -5.
This means that [tex]a_1 = -2, a_n = -5[/tex]
Sum of the first 22 terms
[tex]S_{22} = \frac{22(-2+a_{22})}{2} = 11(-2+a_{22})[/tex]
In which
[tex]a_{22} = -2 + (22-1)(-5) = -107[/tex]
So
[tex]S_{22} = 11(-2 - 107) = 11(-109) = -1199[/tex]
The sum of the first 22 terms of the sequence is -1199.

A group of friends was working on a student film. They spent $330 on costumes, which was 55% of their total budget. What was the total budget for their student film?
Answers
Answer:
$600
Step-by-step explanation:
Let "x" represent their total budget for the film.
Amount spent on costumes = $330
Percent spent on costumes = 55%
Therefore:
55% of x = $330
55/100 × x = 330
55x/100 = 330
Cross multiply
55x = 100 × 330
55x = 33,000
Divide both sides by 55
x = 33,000/55
x = 600
Total budget = x = $600
1. If 5x + 6 = 10, what is the value of 10x + 3?
Answers
All because, we only need to find the value of x.
We are given two equations.
5x + 6 = 10 and 10x + 3 =?
So, we will find the the value of x in the first equation, so that we can substitute the value of x in the second one and there we are with the answer.
5x + 6 = 10
For finding the value of x, all we have to do is,
Transpose the number 6 to 10
Therefore. 5x = 10 - 6 ( Take the equal sign as The Magic Bridge on which if anyone crosses it , will change its sign.)
So we have,
5x = 4
So x = 4/5 ( Multiplication will change to division after crossing the equal sign)
( Doubtful? Substitute the value of x and try!)
Now that we got the value of x,
We can just simply substitute the value of x in the second equation.
10x + 3 = ?
x = 4/5
10*4/5 +3 => 5 and 10 get canceled to 2 at the numerator.
By normal multiplication and then addition, we will get,
8 + 3 = 11
Hope this helps!!!! :)
Answer:
11
