(−0.75x − 7) − (7.5x + 5.4) simplified
Answers
Answer:
[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(-0.75x-7\right)-\left(7.5x+5.4\right)[/tex]
Remove parentheses: (-a) = -a
[tex]=-0.75x-7-\left(7.5x+5.4\right)[/tex]
As we know that: - (7.5x + 5.4) = -7.5 - 5.4
[tex]=-0.75x-7-7.5x-5.4[/tex]
Group like terms
[tex]=-0.75x-7.5x-7-5.4[/tex]
Add similar elements: -0.75x - 7.5x = -8.25x
[tex]=-8.25x-7-5.4[/tex]
Subtract the numbers: -7 - 5.4 = -12.4
[tex]=-8.25x-12.4[/tex]
Therefore, we conclude that:
[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]

Answers
Answer:
The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
Step-by-step explanation:
The college data has large outliers which skews the data, therefore the IQR is better measure of spread.
The high school data does not appear to be skewed so the standard deviation is fine as a measure of spread.

6x+5y=-16
y=7x+5
Answers
Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
Answer:
x = -1
y = -2
( -1, -2 )
Step-by-step explanation:
6x + 5y = -16
They gave us what "y" is and its....
y = 7x + 5
We substitute the "y" in the equation with this "y = 7x + 5
"
6x + 5y = -16
6x + 5(7x + 5) = -16
Now we need to use the distributive property (multiply what is in the parenthesis by "5")
6x + 5 * 7x + 5 * 5 = -16
6x + 35x + 25 = -16
Combine Like Terms ( 6x and 35x)
41x + 35 = -16
Subtract 25 on both sides
41x + 35 - 25 = -16 - 25
41x = -41
Divide by 41 on both sides to isolate the variable
41x/41 = -41/41
x = -1
Now that we have what "x" is (-1) we can use that to find out what "y" is.
y = 7x + 5
Substitute the x with -1
y = 7x + 5
y = 7(-1) + 5
y = -7 + 5
y = -2
x = -1
y = -2
( x, y )
( -1, -2 )

Answer: Only j = 2
============================================
Explanation:
Let's solve for j
[tex]\frac{96}{j} \ge 40\\\\96 \ge 40j\\\\\frac{96}{40} \ge j\\\\2.4 \ge j\\\\j \le 2.4[/tex]
In the second step, I multiplied both sides by j. If j is a positive number, then the inequality sign will not flip. All of the answer choices are positive numbers, so we don't have to worry about the inequality sign flipping.
The last step shows that j = 2.4 or j < 2.4
So j is 2.4 or smaller.
Of the list given to us, only j = 2 fits the description, since something like j = 8 is not 2.4 or smaller.
---------------------------
If j = 2, then,
[tex]\frac{96}{j} \ge 40\\\\\frac{96}{2} \ge 40\\\\48 \ge 40\\\\[/tex]
which is a true statement since 48 is larger than 40. This shows that j = 2 is a solution.
Something like j = 8 does not work because
[tex]\frac{96}{j} \ge 40\\\\\frac{96}{8} \ge 40\\\\12 \ge 40\\\\[/tex]
which is false because 12 is not equal to 40 or larger than 40. This means j = 8 is not a solution. You should find that j = 12 and j = 3 lead to similar false statements.
Of the list given, j = 2 is the only solution.
______________________________
1.) Solve using j = 12:Plug in 12: [tex]\frac{96}{12}[/tex] ≥ [tex]40[/tex]Divide 96 by 12: [tex]=8[/tex] Compare: [tex]8[/tex] ≥ [tex]40[/tex]
So this is False.
2.) Solve using j = 8:Plug in 8: [tex]\frac{96}{8}[/tex] ≥ [tex]40[/tex]Divide 96 by 8: [tex]=12[/tex] Compare: [tex]12[/tex] ≥ [tex]40[/tex]
So this is False.
3.) Solve using j = 2:Plug in 2: [tex]\frac{96}{2}[/tex] ≥ [tex]40[/tex] Divide 96 by 2: [tex]=48[/tex]Compare: [tex]48[/tex] ≥ [tex]40[/tex]So this is True.
4.) Solve using j = 3:Plug in 3: [tex]\frac{96}{3}[/tex] ≥ [tex]40[/tex]Divide 96 by 3: [tex]=32[/tex] Compare: [tex]32[/tex] ≥ [tex]40[/tex]So this is False.
