Answer: 12.9
Step-by-step explanation:
Change each proportion so that it is __ kg = 1 pound and __ stone = 1 pound. Once you do this you should get that 0.45 kg = 1 pound and 0.07 stone = 1 pound. Then, you set up another proportion using these conversions, which would be 0.45 kg over 0.07 stone is equal to 83 kg over x stone. Once you solve for x, you get the answer of 12.9

Answer:
2.(b) w= 3
3. x= -3 or x= 3
Step-by-step explanation:
2.(b) Method 1:
[tex] \frac{2w - 1}{5} + w + 2 = 2w \\ \frac{2w - 1}{5} = 2w - w - 2 \\ [/tex]
Simplify:
[tex] \frac{2w - 1}{5} = w - 2[/tex]
×5 on both sides:
[tex]2w - 1 = 5(w - 2)[/tex]
Expand:
[tex]2w - 1 = 5w - 10[/tex]
Bring constants to 1 side, w terms to the other:
[tex]5w - 2w = 10 - 1[/tex]
Simplify:
[tex]3w = 9[/tex]
Divide both sides by 3:
[tex]w = 9 \div 3 \\ w = 3[/tex]
Method 2:
[tex] \frac{2w - 1}{5} + w + 2 = 2w[/tex]
Multiply by 5 throughout:
[tex]2w - 1 + 5(w + 2) = 5(2w)[/tex]
Expand:
[tex]2w - 1 + 5w + 10 = 4w[/tex]
Simplify:
[tex]7w - 9 = 4w[/tex]
+9 on both sides:
[tex]7w = 4w + 9[/tex]
-4w on both sides:
[tex]7w - 4w = 9[/tex]
Simplify:
[tex]3w = 9[/tex]
Divide by 3 on both sides:
[tex]w = 3[/tex]
3. [tex] \frac{6x - 12}{3} + 4 = \frac{18}{x} [/tex]
Multiply by 3x on both sides:
[tex] \frac{3x(6x - 12)}{3} + 3x(4) = \frac{3x(18)}{x} \\ x(6x - 12) + 12x = 3(18)[/tex]
Expand:
[tex]x(6x) - x(12) + 12x = 54 \\ 6x^{2} - 12x + 12x = 54 \\[/tex]
Simplify:
[tex]6 {x}^{2} = 54[/tex]
Divide by 6 on both sides:
[tex] {x}^{2} = 9[/tex]
-9 on both sides:
[tex] {x}^{2} - 9 = 0[/tex]
Factorise:
*Since a²-b²= (a +b)(a -b),
[tex] {x}^{2} - {3}^{2} = 0 \\ (x + 3)(x - 3) = 0[/tex]
Thus,
x +3= 0 or x -3= 0
x= -3 or x= 3
Answer:
w = 3
Step-by-step explanation:
(6x-12)/3 + 4 = 18/x
Simplify fraction
2x -4 +4 = 18/x
Combine -4+4=0 Divide by 2 to reduce
x = 9/x
Multiply both sides by x
x² = 9
x = 3, -3

Please help ;-;
Answer:
any number more than 0 including 0
Step-by-step explanation:
Answer:
It's 0,
Step-by-step explanation:
Why because 12 is less then if your were going to create a line and 0 is going to be in the middle, that shows in that case 12 is going to be on the left side of the 0 because 12 is a positive number and 0 is not.
Find the unit rate. Unit rate from chart
Answer:
I don't see a chart
Answer:
The unit rate is 15.
Explanation:
Time (hours)
6: $90 90/6 = 15
12: $180 180/12 = 15
18: $270 270/18 = 15
24: $ 360 360/24 = 15
You should find the unit rate by dividing y by x. I divided all of the y's by the x's and I got 15 for all of them, which means that the unit rate is 15.

how do you change y – 5 = - (x – 1) into slope intercept form?
Answer:
y = -x + 6
Step-by-step explanation:
Slope intercept form is y = mx + b.
So distribute the negative sign on the right side to get:
y - 5 = -x +1
Then add the 5 on the left side to both of the sides to get y alone, then you will get:
y = -x +6
That is in slope intercept form.
Which of the following expressions are equivalent to each other?
(Group of answer choices)
1. 2(x+4)
2. 8+2x
3. 2x+4
4. 3(x+4)−(4+x)
5. x+4
Answer:
Number 1 and 2
Step-by-step explanation:
For number 1, you have to distribute the 2 so 2*x=2x, and 2*4=8
That makes 2x+8 and number 2 is the only answer
What the slope is, and if it's a fraction it needs to be simplified.
Answer:
3/2
Step-by-step explanation:
The equation for slope is y/x.
This does not need to be simplified because you don't want a decimal when using slope. To find the slope pick an x value and its corresponding y value

explain why the product of two negative integers is not negative. Use (-1) ·(-1)as an example
The product of two negative integers is not negative because multiplying two negative numbers always gives positive result.
What is multiplication?Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division.
The result of a multiplication operation is called a product.
So, to prove product of two negative integers is not negative
Taking the example of (-1) ·(-1).
Now since multiplying two negative numbers always gives positive result.
Thus, (-1) ·(-1) = +1
which is not negative.
Thus, the product of two negative integers is not negative because multiplying two negative numbers always gives positive result.

Answer:
$308
Step-by-step explanation:
Let x=hourly pay
5x=70
x=14
22(14)
=308
Answer:
$308
Step-by-step explanation:
Let the amount earned be a
and hours be h
a ∝h
a = kh where k is the constant
if $70.00 is earned in 5 hours,
70 = 5k
k = 70/5
k = 14
For 22 hours, it is
a = kh
a = 14 × 22
a = 308
Find the product: (-8)(-6) =
Hi! (-8)(-6) can also be written as -8 × -6. Ignore the negative signs for now.
8 × 6 = 48.
When two negative numbers are multiplied together, the answer is always positive. Think of it as two negative signs (-) make a positive sign (×) when put together.
The answer is -48.

Step-by-step explanation:
GCF=Greatest common factor
we know that it can not be 15 due to 15 not going into 54 due 54 not ending in a 5 or 0. and we know it cannot be 9 either due to 9 not going into 30
so it is 6 because 6 goes into 30 5 times and 6 goes into 54 9 times

Step-by-step explanation:
The data in which table represents a linear function that has a slope of zero? (picture should be in order of abcd, but just incase please when answering save the image and add it to your answer)
Answer:
imma be honest, im not sure how to save images but the correct answer is the one where all the Y-values are 5. this is because the change in y-values is 0, so that would be the numerator over whatever the change in x-values would be, simplifying to zero. so it would be a horizontal line since all the y-values are the same

Find the side length of a square whose area is 121 ft^2
Answer:
The side length is 11 ft
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 ft^2 = s^2
Take the square root of each side
sqrt( 121 ft^2) = sqrt(s^2)
11 ft = s
The side length is 11 ft
