x:y=2:3 and x+y=10.Find value of x and y
Answer:
We know that x is 2
Whilst y is 3
this can be changed due to it’s ratio
So in this code x+y=10
2+3=10
We can do it this way.
2+3=5 (add the ratios)
10/5=2 (Divide the sum by the number needed)
2*2=4 (multiply the quotient for each ratio)
3*2=6 (multiply the quotient for each ratio)
x is 4
y is 6
Answer:

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day!!
We can solve this problem in two steps, Comprehension and Solving
I'll start off with comprehension.
Comprehension
We know that ratios are basically fractions as they both show comparison, so we can make x:y into [tex]\frac{x}{y}[/tex].
We also have another equation, making this problem a system of equations.
Now that we know what to do, we can begin solving!
Solving
We can solve this by first getting our two equations.
[tex]\frac{x}{y}=\frac{2}{3}[/tex]
We can simplify the 2nd equation so that we know what one variable is.
[tex]x+y=10\\x=10-y[/tex]
We can now input our second equation into the first equation.
[tex]\frac{10-y}{y}=\frac{2}{3}\\3(10-y)=2y\\30-3y=2y\\30=5y\\y=6[/tex]
If y is six, then we can use the second equation to solve for x.
[tex]x+6=10\\x=4[/tex]
We know that x is 4 and y is 6.
We can now check our answers.
1st Equation
[tex]\frac{4}{6}=\frac{2}{3}?\\[/tex]
[tex]\frac{2}{3}=\frac{2}{3}[/tex]
2nd Equation
[tex]4+6=10?\\10=10[/tex]
We've proven our answers to be right, therefore, x is 4 and y is 6.

Answer:
17
Step-by-step explanation:
the sequence is plus 3 minus 2. I forgot the actual formula for these kinds of questions but i vaguely remember
an = d (n - 1) + c
I was never able to remember how to use the formula but the sequence would be
5,8,6,9,7,10,8,11,9,12,10,13,11,14,12,15,13,16,14,17,15,18,16,19
if you'll notice, every other number is just one more than the last number...
so the 20th term is 17

Incase you didn't get the notification on your other post.
Answer:
It's D)
C is incorrect because the constant is + 1, not - 8
A is incorrect because the f doesn't go up by 2 for every x value
B is incorrect because 2/3 * 2 would be 4/3 which is 1 1/3, which is wrong because g goes up by 2 every x.
D is correct because f goes up by 1/3, and the y-intercept is 1 (Where the line meets when the x-axis is 0) and 1/3 * 6x is 6x/3 which is 2x, then add the y-intercept to the equation, which should be 2x + 1

Razi is filling bags with party favors for his birthday party. The table to the right shows the number of bags he still needs to fill after 4, 5, 6, and 7 minutes. If he is working at a constant rate, what was the initial number of party favor bags Razi had to fill? 36 48 52 56
Answer:52
Step-by-step explanation:.
By using the concept of the point-slope form of an equation,
The initial number of party favor bags Razi had to fill would be 52.
In this situation, the independent variable (x) is the amount of time in minutes.
The dependent variable (y) is the number of bags remaining.
Since he is working at a constant rate, this makes it a linear function.
In a linear function, the amount he had to fill, to begin with, is the y-intercept.
Since The point-slope form of the equation is,
y - y₁ = m(x - x₁)
First, we find the slope using the formula
m = (y₂-y₁)/(x₂-x₁)
m = (32-36)/(5-4)
m = -4/1
m = -4
Using this and the first point, we have
y - 36 = - 4(x - 4)
Using the distributive property, we have
y - 36 = -4(x)- 4(-4)
y - 36 = -4x--16
y - 36 = -4x + 16
Add 36 to each side:
y - 36 + 36 = -4x + 16 + 36
y = -4x + 52
So, for the initial number of party favor bags Razi had to fill;
Substitute x = 0;
y = - 4 (0)+ 52
y = 52
Hence,
The required initial number is 52.

whats the answer for this??
Step-by-step explanation:
what do you mean "what's the answer for this ?"
you only need to put 3 in place of x (that's what is meant by "x is 3" or x = 3) and then simply calculate.
you know what "squaring" ("something to the power of 2" or x²) means ? it means that you have to multiply that "something" by itself.
y = 3² + 11 = 3×3 + 11 = 9 + 11 = 20

Use the incomplete reaction to complete the activity. Ba(ClO3)2 → ____ + 3O2 In one or two sentences, identify the type of reaction that is occurring and identify the other product. Based on the subscripts of the elements in the other product and the fact that chlorine has seven valence electrons, determine the number of electrons in barium’s (Ba) outer shell.
The missing product of the reaction is BaCl2 and we can see that barium has two electrons on its outermost shell.
The complete reaction is Ba(ClO3)2 → BaCl2 + 3O2. From the reaction equation, we can see that the missing product is BaCl2. The compound is composed of one barium atom and two chlorine atoms.
Since chlorine has seven valence electrons, it means that it requires two electrons from barium to complete its octet in BaCl2. This now means that barium has two electrons in its outermost shell.

sin6x-cos6x=[tex]\sqrt{2}[/tex]
Condense the right side a single sine expression:
sin(6x) - cos(6x) = R sin(6x - t)
Expanding the right side gives
sin(6x) - cos(6x) = R sin(6x) cos(t) - R cos(6x) sin(t)
Then we have
R cos(t) = 1
R sin(t) = 1
Solve for R and t:
(R cos(t))² + (R sin(t))² = 1² + 1²
R² = 2
R = √2
and
(R sin(t))/(R cos(t)) = 1/1
tan(t) = 1
t = arctan(1) = π/4
So we rewrite the equation as
√2 sin(6x - π/4) = √2
Solve for x :
sin(6x - π/4) = 1
6x - π/4 = arcsin(1) + 2nπ
(where n is any integer)
6x - π/4 = π/2 + 2nπ
6x = 3π/4 + 2nπ
x = π/8 + nπ/3
