I need help on this question I don’t get what it’s asking what so ever
Answer:
y=4
Step-by-step explanation:
The question is asking what is the value of y:
Since all lengths have a dash on them they are all equal :
So 3y = y+8
3y = y + 8
First we subtract y from both sides:
3y-y = y+8-y
2y = 8
Divide both sides by 2:
2y÷2 = 8÷2
y = 4
Answer:
Step-by-step explanation:
The question is asking you to find the value of y in a square.
A square has same length in all sides so we can achieve that:
y+8 is equal to 3y
simplifying that, we find out the answer is 4. How?
We have previously acheived that:
y+8=3*y
So we need to find y using these steps:
1. Subtract 3y from both sides:
y+8−3y=3y−3y
−2y+8=0
2. Divide both sides by -2:
y=4

Let's divide each number of crystals by each number of pounds:
7/14 = 1/2
14/28 = 1/2
21/42 = 1/2
28/56 = 1/2
The ratio of crystals to pounds is always 1:2.
This is a proportional relation.

*you can use decimals if needed*
Answer:
116 km squared
Step-by-step explanation:
When you get crazy shapes like this, try and look for the basic ones inside (i.e. triangles, rectangles, etc.) I can find one big triangle and two rectangles, one small and one larger. Vide the attatchment for reference.
Step 1. Find the missing variables, x, y, and z
y = 2
x = 6 - 2 = 4
z = 8 + (4) + 2 = 14
Step 2. Find the area of each shape
Triangle:
Area = bh/2 = (8 x 14)/2 = 56 km sq
Big rectangle:
Area = bh = 8 x 6 = 48 km sq
Small rectangle:
Area = bh = 2 x 6 = 12 km sq
Step 3. Add all the areas together
56 + 48 + 12 = 116 km sq
I hope this helps!
What steps do I need to take to solve the last part of this equation and how do I solve them using the quadratic formula?
Answer:
simplify the radical
Step-by-step explanation:
You have shown the solution using the quadratic formula.
The final step is to simplify the radical expression. That is done by factoring out perfect squares and simplifying the fraction.
[tex]x=\dfrac{\pm\sqrt{120}}{12}=\dfrac{\pm\sqrt{2^2\cdot30}}{12}=\dfrac{\pm2\sqrt{30}}{12}\\\\x=\dfrac{\pm\sqrt{30}}{6}=\left\{\dfrac{1}{6}\sqrt{30}\,,\ -\dfrac{1}{6}\sqrt{30}\right\}[/tex]

Additional comment
0 is the additive identity element, so adding or subtracting zero changes nothing.

Long-billed curlews eat many different kinds of insects, including grasshoppers, as a source of food. It has been shown that pesticide use kills many of these insects. How would you expect an increase in pesticide use to affect to the population of long-billed curlews in the same area
An increase in the use of pesticides in the same area would lead to the population of long - billed curlews decreasing.
How will the population of long-billed curlews be affected by pesticides ?An increase in pesticide use that kills many of the insects that long-billed curlews eat, such as grasshoppers, would likely have a negative impact on the population of long-billed curlews in the same area.
Since grasshoppers and other insects are a primary food source for long-billed curlews, a decline in insect populations due to pesticide use could lead to reduced food availability and increased competition for remaining food sources. This could lead to decreased population size and potentially even local extinctions.

Please Help ! What is the slope of the line?
Answer:
There are 3 ways to find the slope of a line.
I'll use a simple method.
First, let's look at a random point on this line(and make sure it's close to the start of the line).
I'll choose (1,4).
Then, see how much it rises and how far it runs to another fixed point.
Though, in this case we can see that the rise is going down and the run is moving towards the right. So, the slope will be negative since the rise is negative.
You always want to confirm if it'll be a negative or positive slope and which direction the slope is guiding you to.
Now, if we go down 8 and over 3, we'll reach a fixed point of (4, -4).
Therefore, we can infer that the slope of this line will be 8/3.
Answer:
8/3
Step-by-step explanation:
rise over run, only clearly intercepts a point twice.

Solve this pls 4x+32=5x-22
Answer:
54
Step-by-step explanation:
4x + 32 = 5x -22
Group like terms
32 + 22 = 5x - 4x
54 = X
X = 54
Answer:
x = 54
Step-by-step explanation:
4x + 32 = 5x - 22
5x - 4x = 32 + 22
x = 54
To clarify this,
(4 x 54) + 32 = 248
(5 x 54) - 22 = 248

Kalyue drew a rectangle with a perimeter of 20 inches. Then he tried to draw a square with a perimeter of 20 inches. What are the dimensions of square with a perimeter of 20 inches?
Step-by-step explanation:
a square has 4 identical sides.
so, when you have to "walk" around the perimeter of a square you have to go 4 times the same distance.
therefore
20 = 4×side length
side length = 20/4 = 5 in
it is a 5 in × 5 in square.
FYI a rectangle has 2 pairs of sides that are equally long inside their pair.
and so you have in this case a perimeter of
2×6 + 2×4 = 12 + 8 = 20 in
