Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
2x - y = 3 → (1)
x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by subtracting x from both sides
y = 3 - x → (3)
Substitute y = 3 - x into (1)
2x - (3 - x) = 3
2x - 3 + x = 3
3x - 3 = 3 ( add 3 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
substitute x = 2 into (3) for corresponding value of y
y = 3 - 2 = 1
Solution is (2, 1 )

what's the definition of electrolysis
Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

Twelve waters cost $9. How many can you buy with $3?
Answer:
4 bottles of Water
Step-by-step explanation:
First, we need to find how much each water costs. So, I created this equation below.
9/12=?
The answer to the equation is .75, or 75 cents.
So, we can now make yet another equation to find the amount to buy with 3 dollars.
3/.75=?
The answer to that equation is 4.
Thus, the answer is 4 bottles of water.

Solve the equation 14=-(x-8)
Answer:
x = -6
Step-by-step explanation:
Answer:

Step-by-step explanation:
14=-(x-8)
14=−x+8(Distribute)
flip equation:
−x+8=14
Subtract 8 from both sides
−x+8−8=14−8
−x=6
divide by -1 both sides
x=-6

In ΔHIJ, h = 450 cm, i = 210 cm and j=640 cm. Find the measure of ∠I to the nearest degree.
Answer:
10
Step-by-step explanation:
The measure of an angle∠I is 10 degrees between the 450 cm and 640 cm sides.
What is the Cosine Rule?The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
c² = a² + b² − 2ab cos(C)
The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.
In the given triangle ΔHIJ,
Sides:
h = 450 m
i = 210 m
j = 640 m
The angle of ∠I is 10 degrees between the 450 cm and 640 cm sides.
According to the cosine rule,
j² = h² + i² − 2ab cos(I)
Substitute the values in the Cosine Rule,
450² = 210² + 640² - 2(210)(640)cos(I)
After solving we get the value of angle ∠I :
∠I = 9.56038°
Rounded to the nearest degree.
∠I = 10°
Thus, the measure of an angle∠I is 10 degrees.

A boat goes 24 miles at a constant speed in 4 hours against a river current.
It takes the boat 3 hours to go the same distance at the same speed with the
current of the river. What is the speed of the boat and what is the current of
the river?
The speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
A boat goes 24 miles at a constant speed in 4 hours against a river current.
It takes the boat 3 hours to go the same distance at the same speed with the current of the river.
Let's suppose the speed of the boat is x miles/hour and the current of the river is y
x- y = 24/4
x - y = 6 ..(1)
x + y = 24/3
x + y = 8 ..(2)
Adding equation (1) and (2):
2x = 14
x = 7 miles/hour
y = 8 - 7 = 1 miles/hour
Thus, the speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.
