Answer:
-4.7
Step-by-step explanation:
I just went by trial and error till the answer ended up being 0.6. I know that there's a actual way to solve this mathematically, but that's how I did it in school, and so far, I haven't been yelled at for it. Hopefully this was semi-helpful.

x = [?]
Answers
Answer:
x = 35Step-by-step explanation:
[tex]\frac{2}{5} x + 15 = x - 6[/tex]
First multiply through by 5 to eliminate the fraction
That's
[tex]5 \times \frac{2}{5} x + 15(5) = 5x - 30 \\ 2x + 75 = 5x - 30[/tex]
Next using the subtraction property subtract 5x from both sides
That's
[tex]2x - 5x + 75 = 5x - 5x - 30 \\ - 3x + 75 = - 30[/tex]
Next subtract 75 from both sides
[tex] - 3x + 75 - 75 = - 30 - 75 \\ - 3x = - 105[/tex]
Divide both sides by - 3
[tex] \frac{ - 3x}{ - 3} = \frac{ - 105}{ - 3} [/tex]
We have the final answer as
x = 35Hope this helps you

Water covers 70.8%, or about 3.61 108 km2, of the Earth's surface. Approximate the total surface area of the Earth. (Round your answer to the nearest million.)
Answers
This question was not properly written
Complete Question
Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface. Approximate the total surface area of the Earth. (Round your answer to the nearest million.)
Answer:
510,000,000 million km²
Step-by-step explanation:
Let us represent the total surface area of the earth as = x
We are told in the question that:
Water covers 70.8%, or about 3.61 × 10⁸ km², of the Earth's surface.
70.8% = 0.708
Hence,
0.708 × x = 3.61 × 10⁸
x = 3.61 × 10⁸/0.708
x = 361000000/0.708
x = 509,887,005.65km²
Therefore, the total surface are the earth approximately to the nearest million = 510,000,000 million km²

If K is the midpoint of JL , JK = 6x + 11 and KL = 16x +1, find JL.
Pls I need help
Answers
Since K is the midpoint of JL and we know that JK and KL are separate segments of JL, JK and KL are equal to each other.
6x + 11 = 16x + 1
Subtract 6x and 1 from both sides
10 = 10x
Divide both sides by 10
1 = x
We also know that:
JL = JK + KL = 6(1) + 11 + 16(1) + 1 = 6 + 11 + 16 + 1 = 34

what is 3=x+3-5x i dont know what to do
Answers
Answer: 0
Step-by-step explanation:
No matter how you go at it, x is inevtably going to equal 0. To get x by itself, you have to subtract 3 from the right and left side, which leaves 0=x-5x. That leaves you with -4x=0, and when divided, that equals zero.
Answer:
x = 0
Step-by-step explanation:
Given
3 = x + 3 - 5x , that is
3 = - 4x + 3 ( subtract 3 from both sides )
0 = - 4x , thus
x = 0

Step-by-step explanation:
-5< 4x +3 ≤ 7
Subtract 3 from all sides

-8< 4x ≤ 4
Divide all sides by 4
-8/4< 4x/4 ≤ 4/4
-2 < x ≤ 1
Morgan, Dakota and Taylor showed their work solving the equation 7x+5x+1=73. Identify the student with the invalid first step and justify your reasoning. Morgan: 7x+5x+1=73 12x+1=73 Dakota: 7x+5x+1=73 7x+6x=73 Taylor: 7x+5x+1=73 7x+5x=72
Answers
Answer:
Step-by-step explanation:
Given the equation solved by Morgan, Dakota and Taylor expressed as 7x+5x+1=73, to get the value of x, the valid steps are as shown;
7x+5x+1=73
take the sum of 7x and 5x
12x+ 1 = 73
subtract 1 from both sides
12x+1-1 = 73-1
12x = 72
Divide both sides by 12
12x/12 = 72/12
x = 6
Based on the calculation above, the students with invalid first step is Dakota.
Dakota added 5x with 1 to get 6x which is an invalid step because 1 is not attached to a variable x. A function cannot be added to a constant hence making his first step invalid.
Answer:
As you can see, Taylor failed to add 1 to her equation. This ruins the whole first step. She also used 72 instead of 73 for the answer. Taylor is incorrect.

Answers
Answer:
27.38
Step-by-step explanation:
This is the answer because:
1) Standard form means to write the full number
2) First we have to multiply because we have to use order of operations
3) So do 2 x 10 which is 20
4) Then, do 7 x 1 which is 7
5) Next, do 3 x 0.1 which is 0.3
6) Finally, do 8 x 0.01
The new equation is:
20 + 7 + 0.3 + 0.08
This expression equals to 27.38
Therefore, the answer is 27.38
Hope this helps!
