Answer:
4
Step-by-step explanation:
two-thirds = 2/3 (it's easier to write it out in number format)
2/3 = 4/6
So, there are 4 sixths in two-thirds.
Answer:
4 sixths
Step-by-step explanation:

Two glasses of milk and 3 snack bars have a total of 62 carbohydrates, and 3 glasses of milk and 2 snack bars have a total of 58 carbs. Determine how many carbs are in one glass of milk in one snack bar.
Step-by-step explanation:
So looking at this question, we have two variables (1 - a glass of milk; 2 - a snack bar) and two equations to use to solve for the two variables. Remember that for any number of variables, you need that same number or more equations to solve for the variables.
Let's say that a glass of milk is represented by g and a snack bar is represented by s.
So we essentially have two equations here:
4 glasses of milk + 3 snack bars = 88 carbs, or:
4g + 3s = 88
2 glasses of milk + 4 snack bars = 74 carbs, or:
2g + 4s = 74
Now that we have this, we can solve for our equations. There are two ways to do this:
SUBSTITUTION - solve for one variable, then substitute it in
Let's solve for g using the second equation. First, we'll isolate g by subtracting 4s from both sides.
2g = 74 - 4s
Next, we can divide the whole equation by 2 to solve for g.
g = 37 - 2s
Now, we can substitute this into the first equation for g and solve for s.
4g + 3s = 88
4(37 - 2s) + 3s = 88
148 - 8s + 3s = 88
148 - 5s = 88 (now subtract 88 from both sides and add 5s to both sides)
60 = 5s
s = 12
Now we can use this to solve for g in the original equation
g = 37 - 2s
g = 37 - 2(12) = 37 - 24 = 13
ELIMINATION - eliminate one variable to solve for the other, then use that to solve for the first
Let's look at our two equations
4g + 3s = 88
2g + 4s = 74
Let's eliminate the variable g first by multiplying the second question by -2.
4g + 3s = 88
-4g - 8s = -148
If we add these two equations together, we get
-5s = -60
Divide both sides by -5 and we get
s = 12
Now, we can plug s into either equation to solve for g as we did above.
for the following system, use the second equation to make a substitution for why in the first equation. Will mark brainlyest!
2x + y = 5
y + 3 = 2x
a. 2 x + 3 - 2 x = 5
b. 2 x + 2 x - 3 = 5
c. 2 x + 2 x + 3 = 5
Answer:
b
Step-by-step explanation:
get y by itself in the second equation: y= 2x-3
substitute this into the y of the first equation:
2x+2x-3= 5

Step-by-step explanation:
The graph of the function g(x) is a transformation of the parent function f(x)=x2. Which equation describes the function g?
1. g(x)=(x−4)2
2.g(x)=x2+4
3.g(x)=x2−4
4.g(x)=(x+4)2
Answer:
g(x) = x^2 - 4 (Answer #3)
Step-by-step explanation:
The graph of the parent function f(x) = x^2 is a parabola with vertex at (0, 0). That of g(x) is the same, except that the first graph has been translated down by 4 units.
When this happens, the original function f(x) = x^2 + 0 changes to
g(x) = x^2 - 4 (Answer #3)

Step-by-step explanation:
2. Find the area of the regular polygon.
*HINT* - You must solve for the side of the octagon before you can find the area of the figure.
a. What is the Perimeter of the figure?
b. What is the area of the figure?
Answer:
a. 80 units
b. 482.843 units²
Step-by-step explanation:
First things first, we need to solve for the side of the octagon. We can do so by using Pythagorean Theorem: a² + b² = c² where c is the hypotenuse and a and b are the other two sides.
12² + b² = 13²
144 + b² = 169
b² = 25
b = 5
Now that we know half of the side of the octagon is 5, we know that one side of the octagon is 10.
a. To find perimeter we just add every side together (or since every side is the same size, we multiply by 8)
10 × 8 = 80
b. The formula for finding the area of an octagon is 2(1 + radical 2)a² where a is the length of a side. By plugging in to a calculator we get:
2(1 + radical 2)(10)² = 482.843
Simplify this expression. 3-³

Amanda uses the recipe shown to make trail mix for a camping trip. How many cups of M&M's will she need to make 180 cups of trail mix?
Answer:
40 cups
Step-by-step explanation:
7 part nuts and 2 parts M&M makes up 1 trail mix
7 and 2 part = 9 parts in total
There are 180 cups in total, so each part would be:
180/9 = 20 cups = 1 part
Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:
M&Ms required = 2 * 20 = 40 cups

write three to the power of two sevenths in radical form and explain?
Answer:
4782969
Step-by-step explanation:
Answer:
[tex]\sqrt[7]{3^{2}}[/tex]
Step-by-step explanation:
[tex]3^{2/7}[/tex]
^ That is 3 to the 2/7ths power. We know that. Now it needs to be in radical form. That takes a bit of thinking.
If you have a power that is less than one (like 1/2) it is can be written as a root. So say you're given [tex]2^{1/2}[/tex]. That is the same exact thing as saying [tex]\sqrt{2}[/tex]. It's the same thing. You can say it either way.
In the same way, a squared power, like [tex]2^{2}[/tex], is the same as representing it like a fraction, like [tex]2^{2/1}[/tex]. They both mean the same thing.
So by pointing these out, a fraction power = the power / the root.
If that makes sense.
So, with this in mind, let's look at what we have again.
[tex]3^{2/7}[/tex]
So we can split it up to say that 3 is raised to a 2nd power times a 1/7th power.
So we know what a 3 to the 2nd power is: [tex]3^{2}[/tex].
And since we have a fraction that's also included, we now know that is a root. So we can represent that like this: [tex]\sqrt[7]{3}[/tex].
But those two answers need to be combined. We can do that like this: [tex]\sqrt[7]{3^{2}}[/tex]
Answer: [tex]\sqrt[7]{3^{2}}[/tex]
So there it is! I hope that helped you!!
