Answer:
15x to the power of 2
Step-by-step explanation:
3x × 5x = ?
Here we will do more than give you the solution to 3x × 5x. We will also explain and teach you how we came up with the answer, so you can understand it and solve similar problems in the future without help.
In this problem, 3 and 5 are the coefficients and two Xs are the variables. When a coefficient is next to a variable there is an invisible multiplication sign. So you could rewrite the problem as follows:
3 × x × 5 × x =
So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:
3 × 5 = 15
x × x = x2
Then you put the answers together and make the multiplication sign invisible again to get the following answer:
3x × 5x = 15x2

If 3/4 = x/18 , then x is equal to
Answer: x = 13.5
3/4 = x/18
⇔ x = 3/4 .18 = 27/2 = 13.5
Step-by-step explanation:
Answer:x = 27/2
Step-by-step explanation:
Step 1: Cross-multiply
3/4=x/18
(3)*(18)=x*(4)
54=4x
Step 2: Flip the equation.4x=54
Step 3: Divide both sides by 4x/4=54/4x
= 27/2

Please help, I need help on this math question
Answer:
Probably C
Step-by-step explanation:
Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever
For example, 0.2222... or 0.671671.... (The "..." means that it repeats like that forever)
A. 3/7= 0.142857142857142857... (6 repeating digits) This is a repeating decimal because the last six digits continue forever
B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.
C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)
D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.
There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)
But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.
Good Luck! :)
Some questions have the form y = kx, where k is a number. Drag each question to the correct category below. ( X = y/2 ),( y = .11x) , (y = 0.04x), (Z/x =9),( x - 5 =y), (5 = xy ). Has the form y = kx. Can be put into form y = kx. Other.
Answer:
Has the form y = kx
( y = 0.11x)
(y = 0.04x)
Can be put into form y = kx
(z/x = 9)
Other
(5 = xy)
( x = y/2)
Step-by-step explanation:
y = kx
( y = 0.11x)
(y = 0.04x)
kx = y
(z/x = 9)
-----------
( x = y/2 )
( x - 5 = y)
(5 = xy)

Which sequence of transformations creates a similar, but not congruent, triangle?
A) Rotation and translation
B) Reflection and rotation
C) Dilation and rotation
D) Translation and reflection
Answer:
C) Dilation and rotation
Step-by-step explanation:
Dilation changes the size of the shape (how big or small the shape is), rather then changing the shape itself (into a completely different shape). The other options are transformations, but they only move the shape along the graph, nothing else. Hope this helps!
4y (4y - 4) - 4 (-4 + 5 + 4y²)
please simplify <3
Answer:
16y - 4
Step-by-step explanation:
4y(4y - 4) - 4(- 4 + 5 + 4y^2)
16y - 16y - 4(1 + 4y^2)
16y - 16y - 4(4y^2 + 1)
16y^2 - 16y^2 + 4
16y - 4

Explain the power of products property and give an example.
Answer:
We use the power of a product rule when there are more than one variable being multiplied together and raised to a power of something. The power of a product rule tells us that we can simplify a power of a power by multiplying the exponents and keeping the same base.
If x-y=6 and x^2+y^2=24, find x^3-y^3.
Answer:
162.06
Step-by-step explanation:
sorry i'm not the best an explaining but i'm confident in my answer.
the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)
then we have this
x-y=6
x+y=4.90
I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)
In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get
2x=10.9 (the y cancels out)
now we have a simple equation and all that is left is to solve it
10.9/2=5.45
x=5.45
Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.
(5.45)-y=6
y= - .55
now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06
Therefore x³-y³≅162.06!

Katya cut part of the jump rope off to make it shorter. The new length is 8 and StartFraction 1 over 6 EndFraction feet. The difference between the original length and the new length is StartFraction 5 over 6 EndFraction foot. The equation x minus 8 and StartFraction 1 over 6 EndFraction = StartFraction 5 over 6 EndFraction can be used to represent this problem, where x is the original length of the rope. What was the original length of the rope?

Patrick wants to rent a canoe and has a $15 coupon to use at Cool Canoes. The fee for canoe rental is $20.00 per hour. Which equation represents the total cost of renting a canoe, where c is the cost of renting a canoe and h is the number of hours it is rented?
h = 15 − 20c
c = 20h − 15
h = 20c + 15
c = 15h + 20
Answer:
c= 20h-15
Step-by-step explanation:
Trust me :)
Since its $20 an hour, the variable h represents the number of hours.
Then since he has a coupon for $15 off, then that needs to be subtracted because a coupon is used to save money.
