Which value of x satisfies the inequality below?
13< x
Answers
Answer:
20
Step-by-step explanation:
since the sign is pointing to the "greater number"
any number over 13 is fine
The value of x can be 14, 15, .... and so on.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12. This is a real-world example of an inequality.
Given:
13< x
So, we have to choose the value which are greater than 13.
The value of x cannot be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.
Thus, the value of x can be satisfies by 14, 15, .... and so on.

solve the linear equations elimination -2x+3y= 7 5x+8y= -2
Answers
Answer:
x=-2, y= 1
Step-by-step explanation:
Given data
-2x+3y= 7 --------------1
5x+8y= -2--------------2
Multiply 1 by 5 and 2 by 2 and add
-2x+3y= 7 X 5
5x+8y= -2 X 2
-10x+15y= 35
10x+16y= -4
0x+31y= 31
31y= 31
y= 31/31
y= 1
put y= 1 in eqn 1
-2x+3y= 7

. Stephanie has a jewelry box shaped like a cube with a volume of 125 cubic inches. Write an expression to find the edge length of the jewelry box in inches.
Answers
Answer:
25
Step-by-step explanation:
To get this right, we need to get the correct formula for the volume of a cube.
Imagine this:
What is the area of a square? Easy ! Length of the edge times itself. You can imagine what this means as the edge if the we have one line E move straight along an E-long line, the path it made is the square.
Similarly to the cube. Imagine what can be a volume of a cube with edge E that has something to do with the edge?
That's right. A square with edge Emove vertically straight in a E-long line. So the correct volume should be the area of the square times the length of its edge. But the area of the square is already the edge times itself
In formula, if a cube has volume V and edge length E, we have the equation.
V = E×E×E

We know that x = 3, and that we need to add x (which equals 3) to 6.
So, all we need to do is add 6 + 3.
6 + x = 9
We know this because for the expression 6 + x, we replace x with it's given value, which is 3.
