The cost of each bag of gummy bears= $1
Let,s take the cost of a bag of gummy bears to be x and the cost of each chocolate bar to be y.
So from the given question, we get out the first equation as
7 x + 3 y = $22 ------(1)
and the second equation is
3 x + 1 y = $ 8 -------(2)
We have to find the value of x and y by which we will get to know about the cost of each bag of gummy bears and chocolate bar respectively.
Now we have to multiply the second equation with 3
(3 x + 1 y = $8 ) *
we will get :
9 x + 3 y = $ 24 -------( 3)
After equating equations (1 ) and (3)
we get
7 x + 3y = $22-------(1)
9x + 3 y= $24-------(3)
By subtracting of the equation (1) and (3) we get
-2 x = - $2
i.e., x = $1
Now to get the value of y we can put the value of x in any of the above- given equation
Let us put it on equation number (2)
3x + 1 y = $8
= 3 * 1 + y = $ 8
= 3 + y = $ 8
=y = $5
From this, we get the value of x = $1 and y = $ 5 which are the value of gummy bear and chocolate bar
We have to find the value of each gummy bar which is $1

An oceanic -oceanic convergence give rise to volcanic island arcs.
When one oceanic plate subducts another, oceanic-oceanic convergence occurs, leading in the creation of volcanic islands and trenches.Volcanic arcs are volcanoes that originate over a subducting plate and have the shape of an arc. Volcanic activity along a subduction zone, which happens when an oceanic plate falls beneath an oceanic or continental plate, leads to volcanic island arcs.What kind of convergence results in the arcs of volcanic islands?
A volcanic island arc is created when two oceanic plates collide, with the older and heavier of the two subducting beneath the other to start volcanic activity. This process is similar to what happens in an oceanic-continental convergent plate boundary.Learn more about volcanic island arc

Two trains going in opposite directions leave at the same time. train b travels 10 mph faster than train a. in 7 hours the trains are 630 miles apart. find the speed of each.
If two trains going in opposite directions leave at the same time and train b travels 10 mph faster than train a and in 7 hours the trains are 630 miles apart, then the speed of the faster and slower train is equal to 50mph and 40mph respectively.
The speed of each train can be determined by using an algebraic
expression.
As one train travels 10 miles per hour faster than the other, consider x to be the speed of the slower train. In this case, the algebraic expression to find the speeds of each train can be given as,
7x + 7(x + 10) = 630
7x + 7x + 70 = 630
14x = 630 - 70
14x = 560
x = 560 ÷ 14
x = 40 mph
Therefore, x + 10 = 40 mph + 10 mph = 50 mph
Hence, the speed of the faster train is 50 mph and the speed of the slower train is 40mph.

length of a diagonal =
The length of the diagonal is 7.05cm of a square.
The perimeter of the square is 20 cm.
The formula of the perimeter of the square is 4a, where a is the length of the side of the square.

The apparent brightness of stars is measured on a logarithmic scale called magnitude, in which lower numbers mean brighter stars. The relationship between the ratio of apparent brightness of two objects and the difference in their magnitudes is given by the formula
m₂-m₁=-2.5 log b₂ / b₁, where m is the magnitude and b is the apparent brightness.
The star Rigel has a magnitude of 0.12 . How many times brighter is Capella than Rigel?
Capella is 1.09 times brighter than Rigel.
What is logarithmic equation ?In, mathematics a logarithmic equation is inverse of exponential equation. That means, we can easily convert the logarithmic equation into exponential equation and vice versa. The basic form of the logarithm function can be written as .
[tex]log_ax=N[/tex]
where, a is the base of function or equation
x =expression or equation
There are many formulas that are given to us for solving several simple and complex problems based on logarithmic functions and logarithmic equations. Some of them are listed below.
Some important formulas of logarithms are :
log_c a × b = log_c a + log_c b , c is the baselog a/b = log a - log blog a^x = x log alog a^a = 1log (√x) = 1/2 log (x)In the question given here to us,

You have 4 tests so far and you scored 12, 14, 11, 13. You want to keep your overall average at 12. Write and solve
the equation you would use to find what do you need to score on your fifth test to keep this average.
Answer:
You would need to score a 10.
Set-UpThe equation is going to have a total of 5 values where one is unknown. We will call this unknown x and include it as a value in the equation.
Since we are going to have to find an average, we will need a fraction. We also know we will take five total tests. This will equal 12 as this is the desired average.
To start, create the fraction that will add all five values together and divide that by the number of values.
[tex]\displaystyle \frac{12+14+11+13+x}{5}[/tex]
Then, set this equal to 12.
[tex]\displaystyle \frac{12+14+11+13+x}{5}=12[/tex]
SolveTo solve, we will first combine all like terms.
[tex]\displaystyle \frac{50+x}{5}=12[/tex]
Then, divide the fraction.
[tex]\displaystyle 10+\frac{x}{5}=12[/tex]
Now, move the constants to the right side of the equation. To do this, subtract 10 from 12.
[tex]\displaystyle \frac{x}{5}=2[/tex]
Finally, multiply both sides of the equation by 5 to get rid of the denominator.
[tex]x=10[/tex]
Therefore, on test 5, you must score a 10 to maintain an average of 12.
