Answer: x=0
Step-by-step explanation:
[tex]x=4+(4x-4)\\\\x=4+4x-4\\\\x=4x\\\\3x=0\\\\\boxed{x=0}[/tex]
The solution to the equation x = 4 + (x + 4) is 0.
The correct option is "one real solution".
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
Expanding the expression on the right-hand side, we have:
x = 4 + (4x - 4)
x = 4x
Subtracting 4x from both sides, we get:
x - 4x = 0
-3x = 0
Dividing both sides by -3, we get:
x = 0
Therefore, there is one solution to the equation x = 4 + (4x - 4) as the equation simplifies to 0.
So the correct answer is 0, "one real solution".

Leah wants to buy a home for
$380,000, but can only get a loan from the bank for $330,600. What percentage does Leah have to put down in order to pay for the home?
Leah have to put down 13% of the total money in order to pay for the home.
What is a Home Loan ?The amount of money a person borrows from a bank to buy a house is termed as Home Loan.
It is given that
Leah wants to buy a home for $380,000
The amount of money he can get from bank is $ 330,600
The amount of money Leah needs to have
= $ 380000 - $ 330600 = $49400
The percentage Leah have to put down in order to pay for the home is
=($49400 /$380000 ) * 100%
= 0.13 * 100 %

The system of inequalities of the graph is (a) y > x² + 2x - 3 and y > 2x + 3
How to determine the inequalities?The complete question requires that we determine the system of inequalities of the graph (the graph is attached)
Going by the list of options, the equation of the quadratic curve is:
y = x² + 2x - 3
From the graph, we can see that:
The curve uses a dotted lineThe upper part is shadedThe above means that the inequality is greater than i.e. >
So, we have:
y > x² + 2x - 3
The above eliminates options (b) and (c)
From the graph, we can see that the straight line has a positive slope, a dotted line and the upper part is shaded.
The linear inequality in option (a) has the above characteristics.
So, the inequality is:
y > 2x + 3
Hence, the system of inequalities of the graph is (a) y > x² + 2x - 3 and y > 2x + 3

Based on statistics from a worldwide health organization, in there were million people worldwide living with a certain disease, and million deaths from the disease. By , the number of people living with the disease had grown to million, and million deaths were reported. Find the percent change for each statistic, and write any conclusions you can draw.
Based on the statistics from the worldwide health organization, the percentage change in those living with the disease is 19.7% and the change in those who have died is 70%.
This shows that the disease is getting worse and not being treated effectively.
What do the statistics on the disease show?The number of those living with the disease went from 71 million to 40 million:
= (85 - 71) / 71
= 19.7% increase
The percent change in those who have died is:
= (6.8 - 4) / 4
= 70% increase
This shows that the measures being implemented against the disease are not working because both the number of people who have the disease and have died from it has increased.

There is a 45% chance of snow on Friday. Thereis a 78% chance that I will go sledding if it snows. What is the probability that I will go
sledding?
Answer:
35.1% chance of going sledding
Step-by-step explanation:
45% chance of snow on Friday
Convert percentage to decimal form (divide by 100)
45% = 0.45
78% chance of sledding if it snows
Convert percentage to decimal form (divide by 100) to multiply
78% = 0.78
Multiply to find the probability of both occurring
0.78 * 0.45 = 0.351
Convert back into a percentage (multiply by 100)
0.351 = 35.1% chance of sledding

Multiply through by x - 3
Then factor the result
4*(x - 3) / (x - 3) = x*(x - 3)
4 = x * (x - 3 ) Remove the brackets
4 = x^2 - 3x Subtract 4 from both sides
4-4 = x^2 - 3x - 4 Simplify
0 = x^2 - 3x- 4
This factors
0=(x - 4)(x + 1)
Answer
x - 4 = 0
x = 4
x+ 1 = 0
x = - 1

How much of an alloy that is 30% copper should be mixed with 200 ounce of an alloy that is 70% copper in order to get an alloy that is 40% copper?
The alloy of copper will be 600 ounces.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Let us represent
Number of ounce of 30% copper = x
Hence, our Equation will be given below:-
x × 30% + 200 × 70% = (x + 200) × 40%
0.3x + 140 = (x + 200)0.4
0.3x + 140 = 0.4x + 80
Collect like terms
0.4x - 0.3x = 140 - 80
0.1x = 60
x = 60/0.1
x = 600 ounces
Therefore the alloy of copper will be 600 ounces.

Compute the estimated cost of the ending inventory, assuming the gross profit rate is 35%.
The estimated cost of the ending inventory, assuming the gross profit rate is 35% is; $11250
How to find Estimated Cost?Let us first calculate the gross profit;
Gross Profit = Sales * Profit%
Gross Profit = 395000 * 35%
Gross Profit = $138250
Cost of goods sold = Sales - Gross Profit
Cost of goods sold = 395000 - 138250
Cost of goods sold = $256750
Cost of ending inventory = Cost of goods available for sale - Cost of goods sold
Cost of ending inventory = 268000 - 256750
Cost of ending inventory = $11250
