Answer:
The value of x = 20
Step-by-step explanation:
Given the expression
[tex]\frac{4}{5}x\:-\:\frac{1}{4}x\:=\:11[/tex]
The L.C.M of 5,4: 20
Multiply by LCM = 20
[tex]\frac{4}{5}x\cdot \:20-\frac{1}{4}x\cdot \:20=11\cdot \:20[/tex]
Simplify
[tex]16x-5x=220[/tex]
[tex]11x=220[/tex]
Divide both sides by 11
[tex]\frac{11x}{11}=\frac{220}{11}[/tex]
[tex]x=20[/tex]
Therefore, the value of x = 20

One spring day, Caroline noted the time of day and the temperature, in degrees
Fahrenheit. Her findings are as follows: At 6 a.m., the temperature was 52° F. For the
next 3 hours, the temperature rose 2° per hour. For the next 6 hours, it rose 1° per
hour. The temperature then stayed steady until 6 p.m. For the next 3 hours, the
temperature dropped 1° per hour. The temperature then dropped steadily until the
temperature was 60° at midnight. On the set of axes below, graph Caroline's data.
Answer:
Please see attached graph
Step-by-step explanation:
In the attached image you will find the red dots hour per hour that reflect the temperature changes described in the text. The finer red line joins the points to give continuity to the graph.

(100+30x)
30.rº
Answer:
x = 1[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
As you can see, the two angles are supplementary as they lie on the same straight line so they should add up to 180°.
100 + 30x + 30x = 180
Evaluate like terms.
60x + 100 = 180
Isolate 60x.
60x = 180 - 100
= 80
Find x.
x = 80 ÷ 60
x = 1[tex]\frac{1}{3}[/tex]

A bag contains 28 counters all of different colours. Colin chooses one counter and gives it to
Obi, and another counter and gives it to Zeema. In how many ways can Colin do this?
Answer:
756 ways
Step-by-step explanation:
Given
[tex]Counters = 28[/tex]
[tex]Selection = 2[/tex]
Required
Determine the number of ways
The first counter can be selected in 28 ways
The second can be selected in (28 - 1) ways
The number of selection is:
[tex]Selection = 28 * (28 -1)[/tex]
[tex]Selection = 28 * 27[/tex]
[tex]Selection = 756[/tex]
Hence, number of possible selection is 756

Write the values of n such that -15 < 3 ≤ 6
Help please ❤️❤️
Answer:
-4,-3,-2,-1,0,1
Step-by-step explanation:
First, doublepound and simplify it.
-15<3n
3n<6
Solve:
-5<n
n<2
Compound:
-5<n<2.
So the values are -4,-3,-2,-1,0,1
Hope this helps plz hit the crown :D
Answer:
The values of 'n' such that -15 < 3n ≤ 6 will be:
[tex]-5<n\le \:2[/tex]
[tex]-5<n\le \:2[/tex] can also be represented as: -4, -3, -2, -1, 0, 1, 2
Hence, the values of integer n will be:
-4, -3, -2, -1, 0, 1, 2Thus,
[tex]-15<3n\le \:6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-5<n\le \:2\:\\ \:\mathrm{Interval\:Notation:}&\:(-5,\:2]\end{bmatrix}[/tex]
The line graph is also attached below.
Step-by-step explanation:
Given the expression
-15 < 3n ≤ 6
Lets us solve the inequality for n
[tex]-15<\:3n\le \:6[/tex]
Divide all parts by n
[tex]\:-\frac{15}{3}<\frac{3n}{3}\le \frac{6}{3}[/tex]
simplify
[tex]-5<n\le \:2[/tex]
Therefore, the values of 'n' such that -15 < 3n ≤ 6 will be:
[tex]-5<n\le \:2[/tex]
[tex]-5<n\le \:2[/tex] can also be represented as: -4, -3, -2, -1, 0, 1, 2
Hence, the values of integer n will be:
-4, -3, -2, -1, 0, 1, 2Thus,
[tex]-15<3n\le \:6\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-5<n\le \:2\:\\ \:\mathrm{Interval\:Notation:}&\:(-5,\:2]\end{bmatrix}[/tex]

The scatter plot shows a number of CD's (in millions) that were sold from 1999 to 2005. If the trend continued,about how many CDs were sold in 2006?
A. 900
B.850
C.750
D.650
There 650 million CDs were sold in 2006 if there were 800 million CDs sold in 2002, and there were 700 million CDs in 2005 option (D) is correct.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
From the graph:
(2002, 800) and (2005, 700)
We can draw a line for the best fit as follows:
[tex]\rm (y-800) = \frac{700-800}{2005-2002}(x-2002)[/tex]
[tex]\rm (y-800) = 33.33(x-2002)[/tex]
When x = 2006
[tex]\rm (y-800) = -33.33(2006-2002)\\[/tex]
y = 666.68
Which is near 650 million
Thus, there 650 million CDs were sold in 2006 if there were 800 million CDs sold in 2002, and there were 700 million CDs in 2005 option (D) is correct.

Write an equation for the line parallel to the given line that contains C. C(1,4); y = 1/8x-4 (Write in slope intercept form)
Answer:
he equation of the line is parallel to the given line and passing through the point C( 1,4) is x - 8 y + 31=0
slope intercept form
[tex]y = \frac{x}{8} + \frac{31}{8}[/tex]
Step-by-step explanation:
Explanation:-
Given equation of the line
y = 1/8x-4
8 y = x - 32
x - 8 y -32=0
The equation of the line is parallel to the given line a x + b y + k=0
x - 8 y + k=0
This line is passing through the point ( 1,4)
x - 8 y + k=0
1 - 32 + k =0
k = 31
The equation of the line is parallel to the given line and passing through the point C( 1,4) is x - 8 y + 31=0
slope intercept form
8 y = x + 31
[tex]y = \frac{x}{8} + \frac{31}{8}[/tex]

what is the equation of the line in point slope form that has a slope of -7/8, going through point (12,-3)
Answer:
y= (-7/8)x +7.5
Step-by-step explanation:
We know that the form for the equation of a line is
y= mx+b, with m being the slope, so our equation is
y=(-7/8)x+b. As b should be a constant, we need to find b. Plugging (12,-3) in, we have -3 = (-7/8)(12)+b = -10.5+b. Adding 10.5 to both sides, we get b= 7.5, making our equation
y= (-7/8)x +7.5
