Answer:
x = 57
Step-by-step explanation:
Median is the number that is halfway mark. If we are given a data, first we need to arrange them in ascending order and take the middle value. That is called median.
If we have odd number of data, we can easily find the middle value.
For instance, 1, 2, 3, 4, 5 here the number of data = 5 which is odd number.
The middle number is 3.
Therefore, median is 3.
If we have even number of data, we have to take middle two values, add them then divide by 2.
In this case, we are given even number of data
30, 45, x, 100
4 data which is even number of data.
Median is given as 51, we need to find the value of x.
The middle two numbers are 45 and x, we have to add them and divide by 2
Median = [Given: median = 51]
51 =
Multiplying both sides by 2, we get
51*2 = 45 + x
102 = 45 + x
Subtract 45 in both sides, we get
102 - 45 = 45 -45 + x
x = 102 -45
x = 57
In this case, the values are "45" and "x". If we pretend that we know the value of the variable "x" (for example we will pretend that x is 55), then we should have an equation that looks like this: (45+55) ÷ 2 = [median]. What this equation is doing is adding the two closest values to the median (45 and 55) and dividing it by 2, the number of values we are averaging. Now we can solve this equation and simplify it to 100 ÷ 2 which is 50, our median.
So if they give us the median instead of the x value, then we can rewrite the equation to fit your request: (45+x) ÷ 2 = 51. Now we can solve for x:
1. Multiply by 2
(45+x) = 102
2. Subtract 45
x = 57
The x value for your question is 57.

The solution is, graph is D ,which graphs represents the solution set for 7(4x – 1 ) + 6x > –279.
What is inequality?
An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
First, solve the inequality:
7(4x – 1 ) + 6x > –279
solving we get,
34x>-272
x>-8
Since x is greater than -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.
Thus, The solution is, graph is D.

Answer: correct option is B.
multiply first terms and multiply last terms and add and see if we get the middle term
example
(x+2)(2x-3)=2x^2+x-6x
2*2x+x*-3=4x-3x=x=middle term so
a. (2x+5)(3x-1)
2x*-1+5*3x=-2x+15x=13x, no we want -13x
b. (2x-5)(3x+1)
2x*1+-5*3x=2x-15x=-13x correct
answer is B

Answer:
x=3 and y=2
Step-by-step explanation:
We are given with two equations
Y=4x – 10
y=2
From the two equations we already have value y=2
To find out x, plug in 2 for y in the first equation
y= 4x -10
2 = 4x -10
add 10 on both sides
12= 4x
now divide by 4 on both sides
3= x
the value of x=3
so x=3 and y =2
