Explain what the equation 3x = 6 means without using the word equal. Explain why 2 is a solution of the equation.
Answer:
See explanation
Step-by-step explanation:
Given
[tex]3x = 6[/tex]
Solving (a): What the expression means
3 when multiplied by x, gives 6
Solving (b): Why 2 is the solution
We have:
[tex]3x = 6[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} = \frac{6}{3}[/tex]
[tex]x = \frac{6}{3}[/tex]
[tex]x = 2[/tex]
Find the sum of the first 32 terms of the arithmetic sequence 24, 20, 16,
Answer:
[tex]S_{32}[/tex] = - 1216
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 24 and d = a₂ - a₁ = 20 - 24 = - 4 , then
[tex]S_{32}[/tex] = [tex]\frac{32}{2}[/tex] [ (2 × 24) + (31 × - 4) ]
= 16(48 - 124)
= 16 × - 76
= - 1216

On every 3rd day Ivan goes to the gym to exercise. Every 5th day Gavin goes to the gym to exercise. What is the first day Ivan and Gavin will be at the gym on the same day? During 1 hour of television there are 2 shows on. What is the ratio of hours to shows? If you watch 3 hours of television, what will the ratio be?
Answer:
15th day
1 / 2 ; 1 / 2
Step-by-step explanation:
Given :
Ivan = Every 3rd
Gavin = Every 5th
To Obtain the first day they'll be at the gym a together;
Lowest common multiple of the days :
Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24
Multiples of 5 = 5, 10, 15, 20, 25, 30
Lowest common multiple = 15
2.)
Time in hours = 1
Number of shows = 2
Ratio of hours to shows = 1 / 2
Ratio for 3 hours of watching television :
3 * (1 /2) = 3 / 6 = 1 / 2
35%+16/45

Answer:
9 4/9 (this is a mixed fraction btw)
Step-by-step explanation:
Question: 3 4/9 + 5 7/9
Add whole numbers:
3+5 = 8
Combine fractions: 4/9 + 7/9 = 13/9
*fix your improper fraction into a proper one*
so, 13/9 turned into mixed fraction is 1 4/9 (to be clear it's not 14, 1 is the whole number and then the fraction 4/9.) *write it like a mixed fraction please*
anyway, we're not done yet..
8+1 4/9

Solve -7g - 2 = - 30. Show your steps.
Answer:
g = 4
Step-by-step explanation:
-7g - 2 = -30
Add 2 to both sides to get:
-7g -2+2 = -30+2
which is equal to:
-7g = -28
now divide both sides by -7 to get the value of g which is:
g = -28 / - 7
--> g = 4
Answer:
g = 4
Step-by-step explanation:
First you can add 2 to both sides to isolate the x term:
-7g -2 = -30
+2 +2
-7g = -28
Now, you can divide by -7 both sides to find g,
-7g = -28
÷ -7 ÷ -7
g = 4

Hope it is helpful....(a) Construct, using a compass and straightedge, the midpoint of UV and label it M. Then
draw TM, the median from 2T to side UV.
(b) Prove algebraically that the median TM is not perpendicular to UV. Explain.
Please helpppppp
Step-by-step explanation:
a) for the first part, you take your compass and stretch it more than halfway on to line UV. Place the fixed point at V and draw a curve. make sure you keep your compass the same size, put the fixed part of your compass on point U and draw a curve again. both curves should go both upward and downward. Now, your curves should meet at two points. use your straight edge to draw the line that meets at both points. I have drawn an example of what it should approximately look like. for the second part you are simply using your straight edge to draw a line from T down to the median M you previously found. I have drawn a second picture to show you.
b) now to check if they are perpendicular, we must find the slope of each line. I will not be able to do this accurately since I didn't use an exact method to find M, so you must follow my steps.
Step 1: find the slope of UV. To do so, we must take two points from the line. I will take points U and V because they are easiest to see. To find the slope, we can use the equation:
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
where m is the slope.
so, let's define our points.
Point V is (4,4), let's call this point one.
Point U is (14,6), let's call this point two.
So,
x1= 4
y1= 4
and
x2= 14
y2= 6
now, we can plug these into our slope equation.
[tex]m = \frac{6 - 4}{14 - 4} = \frac{2}{10} = \frac{1}{5} [/tex]
You must then use the points T and M in order to solve the second slope. Where T is (2,12). I will keep M as (x1, y1) for now.
The equation should then look like:
[tex]m = \frac{2 - y1}{12 - x1} [/tex]
now, in order for it to be perpendicular to our original slope, it must be the opposite reciprocal, which is the number flipped and made negative. The opposite reciprocal of 1/5 will be -5.
It should NOT be, as we have been told. So, we can state:
"I know that TM is not perpendicular to UV because the UV has a slope of 1/5 and TM has a slope of x, which is NOT the opposite reciprocal on 1/5."
Hope this helps! :)

Answer:
[tex]x = \frac{22}{3}[/tex]
Step-by-step explanation:
Since both CB and ED intersect AD perpendicularly, we can say they are parallel and that ΔACB is similar to ΔAED from Thales intercept theorem. Now, we can set up a proportion from the definition of similar triangles:
[tex]\frac{AB}{AD} = \frac{BC}{DE}[/tex]
We can say that AD = AB + BD(segment addition postulate) and substitute to get AD = 11. Now we can plug in the numbers we have to the proportion:
[tex]\frac{6}{11} =\frac{4}{x}[/tex]
We can cross-multiply to get:
[tex]6x = 44[/tex]
and divide by 6 to get
[tex]x = \frac{22}{3}[/tex]

Which model best represents the data?
y = 47(1.191)x
y = 34(1.204)x
y = 26.9x – 1.3
y = 27x – 4
Answer:
Y=26.9x-1.3is the answer
Step-by-step explanation:
The best model represents y = 26.9x – 1.3
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
As, the data given about productivity is well defined by y = 26.9x – 1.3
As, we have 4 functions so by putting the values we get
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
So, the most accurate is (C)y = 26.9x – 1.3.
