If you are converting from a large unit to a smaller unit, will you always divide?
Explain and include an example.
If you are going from a larger unit to a smaller unit, you multiply by successively. If you are going from a smaller unit to a larger unit, you divide by successively. The factor label method can also be applied to conversions within the metric system.
When you are converting from a larger unit to a smaller unit, you will always divide.
What is unit conversion?
When you are converting from a larger unit to a smaller unit, you will always divide. This is because as you move from a larger unit to a smaller unit, you are breaking the quantity down into more individual parts, hence the need for division.
For instance, to convert 5 m to centimeters;
5 meters x (100 centimeters / 1 meter) = 500 centimeters
As you can see, we divided 5 meters by 100 (the number of centimeters in one meter) to obtain the equivalent length in centimeters, which is 500 centimeters.

Step-by-step explanation:
A garden store purchased a lawn mower and marked it up 160% from the original cost of
$82.67. A week later, the store placed the lawn mower on sale for 10% off. What was the
discount price?
Answer:
$119.04
Step-by-step explanation:
160% of $82.67
= 160/100 * 82.67
= 16/10 * 82.67
= $132.272
After discount,
90/100 * 132.272
= 119.0448
≈ $119.04

Aloha! Looking for some help with an Algebra 1 equation. See photo below. Thank you in advance.
Answer:
(4, 11 ) ; (- 4, 27 )
Step-by-step explanation:
Given
f(x) = x² - 2x + 3 → (1)
f(x) = - 2x + 19 → (2)
Substitute f(x) = x² - 2x + 3 into (2)
x² - 2x + 3 = - 2x + 19 ( add 2x to both sides )
x² + 3 = 19 ( subtract 3 from both sides )
x² = 16 ( take square root of both sides )
x = ± [tex]\sqrt{16}[/tex] = ± 4
Substitute these values into (2) for corresponding values of y
x = 4 : y = - 2(4) + 19 = - 8 + 19 = 11 ⇒ (4, 11 )
x = - 4 : y = - 2(- 4) + 19 = 8 + 19 = 27 ⇒ (- 4, 27 )

Answer:
Equation: y = -3x -2
Graph: Attached below ↓↓↓↓↓
Step-by-step explanation:
The equation is y = -3x + b
We need B at this point.
Since we have a point given to us,( -2, 4)we can input the x and y
Solve:
4 = -3(-2) + b
4 = 6 + b
b = -2
So the equation we have is y = -3x -2
Let's graph the line.
We go 2 units below the x-axis, because the y-intercept is -2, and the slope is -3, so we go down 3 units, and to the right 1.

what is meant by the phrase " equivalent scales"?
Answer:
A household equivalence scale allows for transforming the income in an n-member household into an equivalent one-adult-member household. This is necessary for well-being comparisons across households with different number of members.
An equivalence scale is a measure of the cost of living of a household of a given size and demographic composition, relative to the cost of living of a reference house- hold (usually a single adult), when both households attain the same level of utility or standard of living.
The equivalence scale used in the OECD Income Distribution Database divides household income by the square root of the household size. This implies that, for instance, a household of four persons has needs twice as large as one composed of a single person.
the ratio is equivalent to 28

Answer:
A reflection over the x-axis
Step-by-step explanation:
If you were to put a mirror up to the x-axis and look at one of the shapes, you would "see the" other so we can conclude this is a reflection over the x-axis.
In other words, you could "fold" the graph in half over the x-axis and the two figures would line up.

I’m not understanding how you can solve for this?
Answer:
-1/12
Step-by-step explanation:
You have to substitute the given values of x and y into the expression 4xy². So now the expression would look like this: 4×-1/3×1/4².
Now just simplify from there.
4×-1/3×1/16
-4/3x1/16
-4×1/3×16
-4/48
-1/12

Which fraction is not equivalent to 9/12
15/20
24/32
6/8
16/24
Answer:
16/24
Step-by-step explanation:
9/12–> simplify to 3/4
3/4=15/20
24/32=3/4
6/8=3/4
16/24 is not equal
Answer:
16/24 isn't equivalent to 9/12
Step-by-step explanation:
9/12 = 0.75
Let's see what all the fractions equal to first.
15/20 = 0.75
24/32 = 0.75
6/8 = 0.75
16/24 = 0.667
As you can see, the fraction 16/24 doesn't equal 0.75.
Evaluate |3b - 4a| for a = -3 and b = -5.
Answer:
3
Step-by-step explanation:
To evaluate |3b - 4a| substitute a = -3 and b = -5 in the given expression.
|3(-5) - 4(-3)| , multiply
|-15 +12| , add
|-3| , take the -3 out of the absolute value
3
Hey there!
|3b - 4a|
= |3(-5) - 4(-3)|
= |-15 - (-12)|
= |-15 + 12|
= |-3|
= |3|
= 3
Therefore, your answer is: 3
