Answer:
- 5 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )
= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )
= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]
= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]
= [tex]\frac{-21-11}{6}[/tex]
= [tex]\frac{-32}{6}[/tex]
= - [tex]\frac{32}{6}[/tex]
= - 5 [tex]\frac{2}{6}[/tex]
= - 5 [tex]\frac{1}{3}[/tex]

Using a set of numbers find the mean round to the nearest tenth median mode and range 8,6,3,7,1,6,5,6
Answer:
Mean 5.3, Median 6, Mode 6, Range 7
Step-by-step explanation:
First we arrange the numbers from smallest to the largest. (When you are done count them to see if you have the same amount of numbers that you had before you arrange them.)
1, 3, 5, 6, 6, 6, 7, 8
Mean: is the average of all the numbers :add all numbers / how many numbers we have
(1+ 3+ 5+ 6+ 6+ 6+ 7+ 8) /8 = 42/8 = 5.25 ≈5.3 (rounded to the nearest tenth)
Median: is average of the 2 numbers that are in the middle 1, 3, 5, 6, 6, 6, 7, 8
(6+6)/2 = 6
Mode: is the number that appears the most so is 6
1, 3, 5, 6, 6, 6, 7, 8
Range: is the difference between the highest and the lowest value
1, 3, 5, 6, 6, 6, 7, 8
8-1 = 7
Answer:
Mean- 42
Median- 6
Mode- 6
Range- 7

3 4. What is the slope of the line that passes through (-2, 1) and (8,5)?
Answer: 2/5
Explanation: Ask if you want an explanation!
The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (5 - 1) ÷ (8 - (-2))
= ⁴/₁₀
= ²/₅
Checking my answer:
We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - 1 = ²/₅ (x + 2)
In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

A line passes through the points (0, 9) and (9, 19). What is its equation in slope-intercept form?
Answer:
y = 10/9x + 9
Step-by-step explanation:
To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).
Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
Let (x1, y1) = (0, 9)
and (x2, y2) = (9, 19)
Substitute these values on the formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{19 - 9}{9 - 0} = \frac{10}{9}[/tex]
Therefore, the slope (m ) = 10/9.
Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b ). It is also the value of the y when x = 0.
One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.
Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9

Brandon has a total of 187 postage stamps in his collection.
• he has 48 stamps that are each 14 millimeters wide.
• he has 139 stamps that are each 12 millimeters wide.
what is the total width of the stamps in Brandon's collection?
please help!
Answer:
233.4 Centimeters
Step-by-step explanation:
48 x 10 = 480
48 x 4 = 192
480 + 192 = 672
139 x 10 = 1390
139 x 2 = 272
1390 + 272 = 1662
1662 + 672 = 2334
2334mm = 233.4cm
1) Hot dogs are sold in packs of 10 and hot dog buns are sold in packs of 8. Tommy wants
to know the least number of packs of hot dogs and buns he needs to buy so that he does not
have any left over.
) Complete the table.
Answer:
10, 20,30, 40, 50
Step-by-step explanation:
You times them all by 10 for example: 1x10=10 2x10=20 3x10= 30 4x10=40 and 5x10=50.
If we buy four packs of hot dogs and five packs of buns then we don't have any left over.
What is Least common multiple?The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.
For example: Take two integers, 2 and 3.
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20….
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 ….
Therefore, 6 is the least common multiple of 2 and 3.
Given:
Packs 1 2 3 4 5
Hot Dogs 10 20 30 40 50
Bun 8 16 24 32 40
Also, LCM(10, 8)
10= 2 x 5
8= 2 x 2 x 2
So, LCM(10, 8)= 2 x 2 x 2 x 5 = 40
Hence, If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

Answer:
First number line: 3rd line from 0
Second number line: 7th line from 0
(Sorry if I explained it kinda weird, hope this helps!)
Step-by-step explanation:
On the first number line, you would put the dot on the 3rd line from zero. From 0 to one, it's split into 5 equal parts. 0 is 0/5 and 1 is 5/5. So all you do is plot the dot on 3/5, or the 3rd line from 0.
Same thing with the second number line. Except for this time, it's split into 8 equal parts. Just count to the 7th line in between 0 and 1 and plot the dot.

2.4 hours = ____________ seconds
Answer:
8640
Step-by-step explanation:
Take 2.4 hours, And 1 hour is 60 minutes, and 1 minute has 60 seconds, so 1 hour has 3600 seconds, Do one more hour and you have 7200 seconds, Now you need to add another .4 hours, .4 hours is equal to 40 minutes, so how many seconds are in 40 minutes? 1440 seconds are in 40 minutes, so add 7200 and 1440 and you get 8640.

The cost of $ 385 in 2004 was 10% more than the cost in2003. Calculate the cost in 2003.
9514 1404 393
Answer:
$350
Step-by-step explanation:
Let c represent the cost in 2003. Then we have the cost in 2004 is ...
c + 0.10·c = 385
1.1c = 385
c = 385/1.1 = 350
The cost in 2003 was $350.

Answer: 86 degree
Step-by-step explanation:
The Straight line is 180 degrees so if we minus 180 by the outward degree there will be the degree for inward degree
P: 95 degrees T: 160 degree S: 88 degrees R: 91 degree
The degree for the pentagon is 540 degrees so If I minus 540 by all the four inward degrees there will be the missing last degree
95 + 160 + 88 + 91 = 434 degree
540 - 434 = 106 degree
180 - 106 = 94 degree
So the last inward degree is 94
Finally, if I minus 180 by 94 (the way I used to find inward degree and to find outward degree for now) it equals 86 degree
so X is 86 degree
Sorry if this was too confusing:)
Answer:
1st--> x=135
2nd-->x=74
Step-by-step explanation:
1st:
triangle =180°
180-90=90
90÷2=45
straight line=180°
180-45=135
therefore x=135°
2nd:
pentagon=540°
straight line=180°
180-92=88 for line s
180-20=160 for line q
180-85=95 for line p
180-89=91 for line r
160+95+88+91=434
540-434=106
180-106=74
therefore x=74°
