Answer:
15200mm
Step-by-step explanation:
I just asked googl
Answer:
15.2m is 15200mm
Step-by-step explanation:
you multiply or divide the original number by however many tens places the other measurement is away. So, 15.2(m) is 3 tens places away from (mm) so you would multiply 15.2(m) by 1000 (15.2 x 1000) and you would get 15200
x + 5y = -27
-2x - 5y = 24
Answers
Answer:
Step-by-step explanation:
x+5y=-27
-2x-5y=24
If the signs are the same u minus if they are different u add
So they are different were gonna add
x+5y=-27
-2x-5y=24
-1=-3
You cant divide it further x=-3
Next were gonna subsitute in any equation
x(-3)+5y=-27
-3+5y=-27
+3 to -27
-7+3=-24
5y=24

So, to the question: How many two-fifths are in one?
Well now. How shall we handle this? Hmm…
I know! Let's count the fifths (just numbers, no booze), because it's probably as good a way of getting to an answer as any other way, the question is about fifths, and counting the fifths will at least give us a picture of what we're dealing with here.
Let's jump ahead, to see where we want to end up:
We want to end up with five fifths, also known as 5/5, because 5/5 is the same as 1. How do I know that 5/5 is the same as 1? Well, I know (you'll just have to trust me on this) because saying “5/5” is the same as saying “5 divided by 5”, and saying “1/2” is the same as saying “1 divided by 2", and so on. This is true for all fractions.
So: if 5/5 is the same as 5 divided by 5, then 5/5 equals 1. (You can see why, right? Any number divided into itself is equal to one; also, five goes into five exactly one time!).
And counting the fifths,
1/5 + 1/5 + 1/5 + 1/5 + 1/5 = 5/5 = 1
Or, to count them another way,
1/5 + 1/5 = 2/5
2/5 + 1/5 = 3/5
3/5 + 1/5 = 4/5
4/5 + 1/5 = 5/5
Now that we can see what's inside of that 5/5, let's count how many two-fifths are in five-fifths by adding 2/5 together until we get as close to 5/5 as possible without going over:
2/5 + 2/5 = 4/5
leaving just 1/5 remainder, meaning that there are two 2/5 in 5/5.
We can see that that is true and correct by looking at our little counting exercise above.
Now to make sure our reasoning is clear let's count our fifths again, this time slightly rearranging the way we write the numbers, and then taking things one step further:
(1/5 + 1/5) + (1/5 + 1/5) + 1/5 = 5/5
(2/5) + (2/5) + (1/5) = 5/5
And there it is: there are two 2/5 in 1!
So let's complete the addition for the sake of those like myself who need to see these things through to their furthest conclusion:
(2/5) + (2/5) + (1/5) = 5/5
4/5 + 1/5 = 5/5
5/5 = 5/5
5/5 = 1
1 = 1. And 2/5+2/5=4/5.

Answers
Answer:

Step-by-step explanation:
If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.

17) Find DE 3x - 28 3x – 30 G E F 33
Answers
The numerical length of DE is 11.
We have a Line Segment DG such that E and F is between D and G.
We have to determine the length of DE.
What is Line Segment?A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
According to question, we have -
DE = 3x - 28
EF = 3x - 30
FG = x
DG = 33
Now -
DG = DE + EF + FG
33 = 3x - 28 + 3x - 30 + x
7x = 33 + 58
7x = 91
x = 13
Therefore -
DE = 3x - 28 = 3 x 13 - 28 = 39 - 28 = 11
Therefore - DE = 11
Hence, the numerical length of DE is 11.

Azif is a project manager for a publishing company. His yearly salary is $65,00. This year he will also get a bonus that is 2% of his salary. What is Azif's gross income?
Answers
Answer:
Gross income= $66,300
Step-by-step explanation:
Giving the following information:
Yearly salary= $65,000
Bonus= 2% of the salary
To calculate the gross income, first, we need to determine the monetary value of the bonus:
Bonus ($)= 65,000*0.02
Bonus ($)= $1,300
Now, the gross income:
Gross income= 65,000 + 1,300
Gross income= $66,300

Answer:
The line equation of the line is:
[tex]y=-\frac{3}{8}x+3[/tex]Step-by-step explanation:
Given the two points
(0,3)(8,0)Finding the slope between (0,3) and (8,0)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:0\right)[/tex]
[tex]m=\frac{0-3}{8-0}[/tex]
[tex]m=-\frac{3}{8}[/tex]
Therefore, the slope of the line: m = -3/8
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = -3/8 and the point (0,3)
[tex]y-3=-\frac{3}{8}\left(x-0\right)[/tex]
[tex]y-3=-\frac{3}{8}x[/tex]
Add 3 to both sides
[tex]y-3+3=-\frac{3}{8}x+3[/tex]
Simplify
[tex]y=-\frac{3}{8}x+3[/tex]
Therefore, the line equation of the line is:

PLEASE HELP!!!! On average, Jack can fold his laundry in 30 minutes, but, depending on how much laundry he has, his time can vary from the average by 10 minutes.
Which absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry?
Let x represent the maximum and minimum time.
|x−30|=10
|x+10|=30
|x−10|=30
|x+30|=10
Answers
Answer:
I think it is the third choice
The absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry is, |x−30|=10. So, Option A is correct
What is an Equation ?An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.
For example, 3x+2y=0.
Types of equation
1. Linear Equation
2. Quadratic Equation
3. Cubic Equation
Given that,
On average, Jack can fold his laundry in 30 minutes
How much laundry he has, his time can vary from the average by 10 minutes
So, maximum time can be 40 minutes
And minimum time can be 20 minutes
Therefore, The result is |x-30| =10
