6u+18+9u=-12 simplify
Answer:
u = -2
Step-by-step explanation:
Group
[tex]6u+9u+18=-12[/tex]
Add similar elements in the equation
[tex]15u+18=-12[/tex]
Subtract 18 from all sides
[tex]15u+18-18=-12-18[/tex]
Simplify this
[tex]15u=-30[/tex]
Divide all sides by 15
[tex]\frac{15u}{15}=\frac{-30}{15}[/tex]
Divide 15 by 15, removing u
[tex]\frac{15}{15} = u[/tex]
Transform [tex]\frac{-30}{15}[/tex] by using the fraction rule.
[tex]-\frac{30}{15}[/tex]
Divide 30 by 15.
[tex]\frac{30}{15} = 2[/tex]

The coordinates of the midpoints of the segment with the endpoints are (-1, 0.5)
How to determine the coordinates of the midpoints of the segment with the endpoints?The endpoints of the segment are given as
J = (-6, 3)
K = (4, -2)
The coordinates of the midpoints of the segment with the endpoints are calculated as
Midpoint = 1/2 * (J + K)
So, we have
Midpoint = 1/2 * (-6 + 4, 3 - 2)
Evaluate the sum and the difference
So, we have
Midpoint = 1/2 * (-2, 1)
Evaluate the product
So, we have
Midpoint = (-1, 0.5)
Hence, the coordinates of the midpoints of the segment with the endpoints are (-1, 0.5)

Scientific notation?
The scientific notation of the number 140.02943 is 1.4002943 × 10⁻².
What is termed as the scientific notation?Scientific notation is a technique for expressing numbers that are too large or small to be written in basic decimal form. In some contexts, scientific notation is also recognised as standard form, scientific form, or standard index form.The primary reason for the importance of scientific notation is that it enables us to transform very large or extremely small numbers into much manageable sizes. It is much simpler to work with these numbers when they are written in scientific notation. Scientific notation is also crucial because it ensures that calculations involving large numbers remain accurate, as it is often easy to lose track of successfully counting extremely large numbers. For instance, someone will most likely be able to work with 10¹⁰ rather than 10,000,000,000.The given number is;
140.02943
Shift the 2 decimal to the left of the decimal; because of this, the resultant number will get multiplied by 10⁻².
= 1.4002943 × 10⁻²
Thus, the number in the scientific notations will be written as; 1.4002943 × 10⁻².

Determine which equation is false based on the solution set.
S:{5}
A: 6 = 2y − 4
B: 4(b + 5) = 40
C: one fifth times x plus 16 equals 17
D: −32 = 2(3p − 6)
Answer:
d) -32 = 2(3p - 6) is false.
Step-by-step explanation:
A) 6 = 2y - 4
→ 6 = 2(5) - 4
→ 6 = 10 - 4
→ [ 6 = 6 ]
So, the equation is true.
B) 4(b + 5) = 40
→ 4(5 + 5) = 40
→ 4(10) = 40
→ [ 40 = 40 ]
So, the equation is true.
C) (1/5)x + 16 = 17
→ (5/5) + 16 = 17
→ 1 + 16 = 17
→ [ 17 = 17 ]
So, the equation is true.
D) -32 = 2(3p - 6)
→ -32 = 2(15 - 6)
→ -32 = 2 × 9
→ [ -32 ≠ 18 ]
So, the equation is false.
Carla is riding her tricycle in a race. We only know that 20 seconds after the race began, she was 55 meters from the starting line, and 30 seconds after the race began, she was 85 meters from the starting line. Find the equation of the line describing Carla’s motion during the race, where y represents her distance from the starting line in meters, and x represents the time since the race began in seconds.
The equation of a line describing Carla's motion during the race is y = 3x - 5.
What is slope?The slope is defined as the rate of change of the y-axis with respect to the x-axis.
As we are representing y as distance in meters and x as time in seconds we can form two co-ordinates for the distance Carla covered, They are
(20,55) and (30,85).
Now to form an equation of a line we have to first determine the slope(m) and y-intercept (b).
We know slope(m) = (y₂-y₁)/(x₂-x₁).
∴ Slope(m) = (85 - 55)/(30 -20).
= 30/10.
= 3.
Now, The equation of this line can be written as slope intercept form as y = mx + b.
55 = 3(20) + b.
b = -5.
So, y = 3x - 5 is our required equation of this situation represented by a line.

A certain star is 3.9 x 10^2 light years from the Earth. One light year is about 5.9 x 10^12 miles. How far from the earth (in miles) is the star?
Answer: The star is 2 quadrillion( 1 followed by 15 zeroes) and 301 trillion( 1 followed by 12 zeroes) miles away from Earth. To shorten this into scientific notation(the format used to write large numbers) is: 2.301 x 10^15.
Step-by-step explanation: First, find the exact value of the units of measurement, which in this case is light years. To do so, your best choice would be to separate the equation given for light years. (Note: the line through the middle is just to separate two very similar series of steps.)
1. 5.9 x 10^12 into 5.9 x (10^12)
2. 10^12 = 1,000,000,000,000. 10^12 is the same as adding 11 zeroes since it is multiplying by tens, not 12 zeroes since there is already a zero on the ten. This number is one-trillion(we will shorten this number to 1T).
3. 5.9 x 1T = 5.9 T. Don't get nervous of the big numbers, this is the same as doing 5.9 x 1 and then adding a name afterwards. Now that we have our number, we must remember the question is asking for miles, so keep in mind this large number is the miles.
4. 5.9T --> 5.9 | T Take off the T from 5.9T for now to make this problem a little simpler for this next part.(Note: the | is a separator)
------------------------------------------------------------------------------------------------------------- 5. 3.9 x 10^2 into 3.9 x (10^2)
6. 10^2 = 100. 10^2 is the same as multiplying adding one zero to the ten. This number is one-hundred.
7. 3.9 x 100 = 390. Please remember that this step is to find the number of light years away from the Earth.
8. 390 x 5.9 = 2301. This is the number of lightyears times the number of miles without the zeroes. The next step is to add the zeroes which brings the number into trillions.
9. 2301 | T --> 2301T. Next is to simplify this number, since every zero after 3 makes the number into a different name, this number is now has 15 zeroes. This number(one-quadrillion) will be shortened to Qu.
10-ish. 2301T = 2.301Qu. This is the name of a number with 15-17 zeroes.
10. 2.301Qu = 2.301 x 10^15. This is just turning the number into scientific notation.

what is the least whole number that rounds to 230000 when rounded to the nearest ten thousand?
The least whole number that can be rounded to 230,000 is 225,000.
What is the least whole number?The ten thousand number (10,000) is usually the fifth digit in a number when counting from the right to the left. For example, in 132,456, 3 is the ten thousand number.
To round off to the nearest ten thousand, if the thousand digit is equal to or greater than 5 (i.e. 5,6, 7, 8, 9), 1 is added to the ten thousand digit and other numbers less than the ten thousand digit becomes 0. For example, when 234,612 is rounded to the nearest ten thousand, the number becomes 235,000.
If the thousand digit is less than 5 (i.e. 0, 1, 2, 3, 4), there is no change in the ten thousand digit other numbers less than the ten thousand digit becomes 0. For example, when 234,412 is rounded to the nearest ten thousand, the number becomes 234,000.
The numbers that can be rounded off to 230,000 are: 225,000, 226,000, 227,000, 228,000, 229,000, 230,000, 231,000, 232,000, 233,000, 234,000

the 3rd term of a linear sequence is 17. the 45th term is 269. determine the formula for the nth term.
Step-by-step explanation:
a linear or arithmetic sequence has a start value as first term, and then every following term is created by adding the same constant to the previous term.
a1 = a
a2 = a1 + c = a + c
a3 = a2 + c = a + c + c = a + 2c
a4 = a3 + c = a + c + c + c = a + 3c
...
as we can easily see
an = an-1 + c = a + (n-1)c
in our case
a3 = 17 = a + 2c
a = 17 - 2c
a45 = 269 = a + 44c = 17 - 2c + 44c = 17 + 42c
252 = 42c
c = 6
a = 17 - 2c = 17 - 2×6 = 17 - 12 = 5
so,
an = 5 + (n-1)×6

paced the long shadow of the telephone pole and found that it was 35 meters long. How high is the telephone pole in meters? Enter your answer
with one digit to the right of the decimal point.
The telephone pole will stands 10.5 meters tall.
Given shadow of you = 5 meters
The true height is 1.5 meters.
We must determine the telephone pole's height because its lengthy shadow is 35 meters long.
Assume that x is the height of the telephone pole..
Now we can write this as
height of shadow/ actual height
5 / 1.5 = 35 / x
By cross multiplication we get
5 * x = 35 * 1.5
We get it by dividing '5' by both sides
x = 35 * 1.5 / 5
x = 10.5 meters
