Answer:
See Explanation
Step-by-step explanation:
1.
Given
[tex]y = 6x - 11[/tex]
[tex]-2x - 3y = -7[/tex]
Solve for x and y
In the first equation, we have: [tex]y = 6x - 11[/tex]
Substitute [tex]6x - 11[/tex] for [tex]y[/tex] in the second
[tex]-2x - 3y = -7[/tex]
[tex]-2x - 3(6x - 11) = -7[/tex]
[tex]-2x - 18x + 33 = -7[/tex]
[tex]-20x+ 33 = -7[/tex]
[tex]-20x= -7-33[/tex]
[tex]-20x= -40[/tex]
Divide through by -1
[tex]20x = 40[/tex]
[tex]x = 40/20[/tex]
[tex]x = 2[/tex]
Recall that:
[tex]y = 6x - 11[/tex]
[tex]y = 6 * 2 - 11[/tex]
[tex]y = 1[/tex]
2,
Given
[tex]-3x - 3y = 3[/tex]
[tex]y = -5x - 17[/tex]
In the second equation, we have: [tex]y = -5x - 17[/tex]
Substitute [tex]-5x - 17[/tex] for [tex]y[/tex] in the first equation
[tex]-3x - 3y = 3[/tex]
[tex]-3x - 3(-5x - 17) = 3[/tex]
[tex]-3x + 15x + 51 = 3[/tex]
[tex]12x + 51 = 3[/tex]
[tex]12x=3 - 51[/tex]
[tex]12x=-48[/tex]
[tex]x = -48/12[/tex]
[tex]x = -4[/tex]
Recall that: [tex]y = -5x - 17[/tex]
[tex]y = -5 * -4 - 17[/tex]
[tex]y = -3[/tex]
3. Given
[tex]-4x + y = 6[/tex]
[tex]-5x - y = 21[/tex]
Add both equations to eliminate y
[tex]-4x - 5x + y - y = 6 + 21[/tex]
[tex]-9x= 27[/tex]
Solve for x
[tex]x = 27/-9[/tex]
[tex]x = -3[/tex]
Substitute -3 for x in the first equation: [tex]-4x + y = 6[/tex]
[tex]-4 * -3 + y = 6[/tex]
[tex]12 + y = 6[/tex]
[tex]y = 6 - 12[/tex]
[tex]y = -6[/tex]
4. Given
[tex]-7x - 2y = -13[/tex]
[tex]x - 2y = 11[/tex]
Make x the subject in the second equation
[tex]x - 2y = 11[/tex]
[tex]x = 11 + 2y[/tex]
Substitute 11 + 2y for x in the first equation
[tex]-7x - 2y = -13[/tex]
[tex]-7 (11 + 2y) - 2y = -13[/tex]
[tex]-77 -14y - 2y = -13[/tex]
[tex]-77 -16y = -13[/tex]
[tex]-16y = -13 + 77[/tex]
[tex]-16y = 64[/tex]
[tex]y = 64/-16[/tex]
[tex]y = -4[/tex]
Substitute -4 for y in [tex]x = 11 + 2y[/tex]
[tex]x = 11 + 2 * -4[/tex]
[tex]x = 11 -8[/tex]
[tex]x = 3[/tex]
5. Given
[tex]-2x + 6y = 6[/tex]
[tex]-7x + 8y = -5[/tex]
Multiply the first equation by 7 and the second by - 2 to eliminate x
The first
[tex]7(-2x + 6y = 6)[/tex]
[tex]-14x + 42y =42[/tex]
The second
[tex]-2(-7x + 8y = -5)[/tex]
[tex]14x - 16y = 10[/tex]
Add the resulting equations
[tex]-14x + 42y =42[/tex]
[tex]14x - 16y = 10[/tex]
------------------------------
[tex]-14x + 14x + 42y - 16y = 42 + 10[/tex]
[tex]42y - 16y = 42 + 10[/tex]
[tex]26y = 52[/tex]
Solve for y
[tex]y = 52/26[/tex]
[tex]y = 2[/tex]
Substitute 2 for y in [tex]-2x + 6y = 6[/tex]
[tex]-2x + 6 * 2 = 6[/tex]
[tex]-2x + 12 = 6[/tex]
[tex]-2x = 6 -12[/tex]
[tex]-2x = -6[/tex]
Solve for x
[tex]x = -6/-2[/tex]
[tex]x = 3[/tex]

Answer:
The answer is below
Step-by-step explanation:
Let's work it out slowly
A)
$18.79 + $2.11 - $1.92 + $17.28
- 18.79 + 2.11 + 17.28 = 38.18
- 38.18 - 1.92 = 36.26
Ans = $36.26
B)
$7.45 + $24.45 + $74.17 + $76.52
- 7.45 + 24.45 = 31.9
- 74.17 + 76.52 = 150.69
- 150.69 + 31.9 = 182.59
Ans = $182.59
C) $98.45 - $10.63 + $2.82 - $20.26
- 98.45 - 10.63 - 20.26 = 67.56
- 67.56 + 2.82 = 70.38
Ans = $70.38
Hope you understand

Translate the sentence into an inequality.
The sum of a number times 10 and 16 is at most 28.
Use the variable c for the unknown number.
Given:
The sum of a number times 10 and 16 is at most 28.
To find:
The inequality for the given statement.
Solution:
Let the unknown number be c.
A number times 10 = 10c
Sum of a number times 10 and 16 = 10c + 16
At most 28 = Number should less than or equal to 28.
The inequality for given sentence is
[tex]10c+16\leq 28[/tex]
Therefore, the required inequality is [tex]10c+16\leq 28[/tex].

Answer:
1. -12 2. you get - 3. -6
Step-by-step explanation:
Well hope that makes sense. Please heart.
12 plus -12 is 0. -3 plus 2 is -1 or -. -4 plus -2 is -6.
You add -12 to 12 to make it zero.
If you have - - - and add + + you get -1.
If you have - - - - and add - - you get -6.

A printing machine produces labels.Four percent of the labels produced are defective.Suppose 372 labels were defective.
how many labels are not defective?
Answer:
8928
Step-by-step explanation:
If 4% is 374, what is 1%? so 374/4
374 = 4%
93 = 1%
Now if 4% is defective, how many is not defective?
100% - 4% = 96%
If 1% is 93 then what is 100%?
8928 = 96%
There were 8,928 labels are not defective.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that labels are created using a printing press. Four percent of the labels that are created are inaccurate.
Let the total number of labels would be x
As per the question, 372 labels were defective.
So 4% of x = 372
⇒ 4x/100 = 372
⇒ x = 37,200/4
⇒ x = 9,300
Since 4% is defective labels,
So labels are not defective: 100% - 4% = 96%
Now, we have to calculate the evaluation of 96% of 9,300.
⇒ (96/100)9,300
⇒ (0.96)9,300
⇒ 8,928
Therefore, there were 8,928 labels are not defective.

Answer:
88 degrees
Step-by-step explanation:
First, notice that when you rotate a point 272 degrees clockwise, there will be 88 more degrees before it returns to its original point (since a 360 turn is equivalent to not moving, and 360-272=88).
Because of that, we can deduce that rotating a point 88 degrees counterclockwise will be equivalent to rotating it 272 degrees clockwise.
We can know that that's the smallest possible positive answer, because any angle smaller than 360 will be the smallest possible way to express it.

What is a rational number and how do you know?
For a recent season in college football, the total number of rushing yards for that season is recorded for each running back. The mean number of rushing yards for the running backs that season is 790 yards. One running back had 1,637 rushing yards for the season, which is 2.42 standard deviations above the mean number of rushing yards. What is the standard deviation of the number of rushing yards for the running backs that season?
(A) 250 yards
(B) 300 yards
(C) 350 yards
(D) 400 yards
(E) 450 yards
Answer:
(C) 350 yards
Step-by-step explanation:
From available information
Mean = 790
1 running back = 1637 yards
Standard deviation above mean = 2.42
Using formula
z =( x - mean)/sd
2.42 = (1637-790)/sd
2.42 = 847/sd
We cross multiply
2.42sd = 847
Divide through by 2.42
Sd = 847/2.42
Sd = standard deviation = 350
So our answer is 350 and therefore option c.
