By analyzing the equation and using provided options, we find that the right values for the digits x, y, and z are 1, 2, and 3 respectively. When multiplied together, the product (x)(y)(z) equals 6.
Explanation:The mathematical problem you've presented is akin to a simple addition of numbers, but with a twist: the digits x, y, and z each represent different unknown digits. Our task is to determine the value of the product (x)(y)(z) given the vertical addition:
4zLooking at the addition, we can see that when we add the second digit of the second row (2) with the first digit of the third row (x), the result must be a digit with a 1 carried over because there is a 1 in the hundred's place of the result. That means 2 + x has to be equal to 10 or 11 (since x is a digit, the highest value for x could be 9).
Using the option provided (d) x. 1, y. 2, z. 3, we can see that the column with z's would sum to 7 (4z), the column with x's would sum to 11 (since 1 + x = 11, x = 1), and the column with y's would sum to 14 (since y would then be 2) which fits the pattern of the problem provided. Therefore, the values for x, y, and z are 1, 2, and 3 respectively.
The value of (x)(y)(z) is thus 1 × 2 × 3 = 6.
Final answer:
To find the value of (x)(y)(z), we need to solve the equation 4z/27 + x5/y14 = 0. By substituting different values for x, y, and z, we find that (x)(y)(z) = 6.
Explanation:
To find the value of (x)(y)(z), we need to solve the given equation:
4z/27 + x5/y14 = 0
Since x, y, and z each represent a different digit from 0 to 9, we can try different values to solve for (x)(y)(z).
Let's start with the first term: 4z/27. The only possible value for z is 2, because 4z/27 must give us a rational number. So, let's substitute z = 2 into the equation:
4(2)/27 + x5/y14 = 0
8/27 + x5/y14 = 0
Next, let's solve for the second term: x5/y14. To make this term equal to 0, we can set x = 1 and y = 3. Substituting these values into the equation:
8/27 + 15/314 = 0
Now, let's find the value of (x)(y)(z) = (1)(3)(2) = 6.

If 10 pencils and 7 erasers cost $4.23 and 3 pencils and 1 eraser cost $0.95, what is the cost of 2 erasers?
Answer: $0.58
Step-by-step explanation:
Let x represent pencil and y represent eraser
10x + 7y = 4.23 → 1(10x + 7y = 4.23) → 10x + 7y = 4.23
3x + y = 0.95 → -3(3x + y = 0.95) → -21x - 7y = -6.65
-11x = -2.42
÷-11 ÷-11
x = 0.22
3x + y = 0.95
3(0.22) + y = 0.95
0.66 + y = 0.95
y = 0.29
2y = 2(0.29) = 0.58

B. No. (0,0) satisfies y > 2x - 1 but does not satisfy y ≤ x^2 - 4.
C. Yes. (0,0) satisfies both inequalities.
D. No. (0,0) does not satisfy either inequality.
Answer:
option-B
Step-by-step explanation:
we are given system of inequality as
[tex]y\leq x^2-4[/tex]
[tex]y>2x-1[/tex]
now, we can check solution
At (0,0):
we can plug x=0 and y=0
and check inequality
[tex]0\leq 0^2-4[/tex]
[tex]0\leq -4[/tex]
so, this is FALSE
now, we can check second inequality

So, this is TRUE
so, option-B
Answer: Hello mate!
we want to know if the pair (0,0) is a solution for the system, where the usual notation for a pair is (x,y), and the system is:
y ≤ x^2 - 4
y > 2x - 1
The first step is replacing the numbers in the system by the numbers in the pair, and look if the pair is a solution or not.
the first inequality gets:
y ≤ x^2 - 4
0 ≤ 0^2 - 4
0 ≤ - 4
This is false, so (0,0) is not a solution for this inequality.
Now let's see the second one:
y > 2x - 1
0 > 2*0 - 1
0 > -1
This is true, then the pair (0,0) is a solution for this inequality.
then the answer is the option B, the pair (0,0) is not a solution for the system, satisfies y > 2x - 1 but does not satisfy y ≤ x^2 - 4.
which is a correct two-column proof? Given: <H and <X are supplementary. prove: l || n
Answer:
option-B
Step-by-step explanation:
we are given
<H and <X are supplementary angles
so,
<H+<X=180
we know that
<H and <E are vertically opposite angles
so, they must be equal
<H=<E
we can plug it
<E+<X=180
It means that angle(E) and angle(X) are supplementary angles
and these two angles are same side interior angles
By using same side interior angles converse
so, line(l) and line(n) must be parallel
so, option-B
Answer:
Option (B) is correct
Step-by-step explanation:
∠H and ∠X are supplementary as given, ∠H + ∠X = 180
And, ∠H = ∠E ( Vertical opposite angles are equal )
So, by substitution ∠E + ∠X = 180
So, the sum of same side interior angles ∠E and ∠X is 180 therefore, by using converse of same-side Interior angles theorem we get l║m.
The correct option is B

Final answer:
In mathematics, solving absolute value problems involves finding the value of an unknown variable within the absolute value expression. Here is a step-by-step process to solve an absolute value problem: Isolate the absolute value expression, remove the absolute value bars, solve the resulting equations, and check the solution. For example, to solve the equation |2x - 3| = 5, isolate the absolute value, solve for x, and check the solutions.
Explanation:
In mathematics, solving absolute value problems involves finding the value of an unknown variable within the absolute value expression.
Here is a step-by-step process to solve an absolute value problem:
Isolate the absolute value expression on one side of the equation.
Remove the absolute value bars by considering both positive and negative cases.
Solve the resulting equations to find the values of the variable.
Check the solution to ensure it is valid by substituting it back into the original equation.
For example, to solve the absolute value equation |2x - 3| = 5, we isolate the absolute value by moving the constant term to the other side: 2x - 3 = 5 and 2x - 3 = -5. Then we solve both equations separately to find the values of x: x = 4 and x = -1. Finally, we check the solutions by substituting them back into the original equation to ensure they satisfy the equation.
Aidens age Is 1/7 of his father’s age. His father will be 61 years old in five years. In how many years will Aidens age be 1/5 of his fathers age ?
Answer:
see below PLEASE GIVE BRAINLIEST
Step-by-step explanation:
Aiden's father will be 61 in 5 years:
61 - 5 = 56
Since Aiden is 1/7 of his father's age just divide his father's age by 7:
56 ÷ 7 = 8 Aiden is currently 8 years old.
Aiden his father is he 1/5 his fathers age
9 57 9 x 5 = 45 NO
10 58 10 x 5 = 50 NO
11 59 11 x 5 = 55 NO
12 60 12 x 5 = 60 YES
Aiden is 1/7 of his father's current age, and his father is currently 56. Given that we want Aiden's age to be 1/5 of his father's, the number of years that would need to pass is 14 years.
Explanation:Firstly, let's determine Aiden's current age and his father’s current age. We know that Aiden's age is 1/7 of his father’s age, and that his father will be 61 in five years, meaning that his father is currently 56. Thus, Aiden, being 1/7 of his father’s age, is 8 years old.
Let's denote the number of years that we are looking for as 'x'. In 'x' years, Aiden will be 8+x years old, and his father will be 56+x. For Aiden’s age to be 1/5 of his father’s age, the following must be true: (8+x) = 1/5*(56+x). Solving this equation gives us x = 14. Therefore, in 14 years, Aiden's age will be 1/5 of his father's age.

Answer: Choice D) ordered pair is not a solution to the second equation
We can see this by replacing x and y with 1 and -4 respectively
2x + y = 4
2*1 + y = 4 .... replace x with 1
2*1 + (-4) = 4 ... replace y with -4
2 - 4 = 4
-2 = 4 .... this equation is false because -2 and 4 are different values
The last equation being false means that the original equation 2x+y = 4 is also false when (x,y) = (1,-4). Therefore, this ordered pair is not a solution to the second equation 2x+y = 4
A solution to the system must make BOTH equations true simultaneously, not just one.

which variable is most important to the following problem? A company has 95,000 shares of stock to sell. A stockbroker decides to buy 150 shares of the stock for each of her 250 clients. How many shares will the company have left to sell after the stockbroker makes her purchase
A. the number of shares the stockbroker bought for each customer
B. the price of one share
C. the number of shares remaining after the stockbroker buys shares for her customers
Answer: the price of shares is never mentioned
the number of shares bought for each customer (what customers? does customer = client?) .... bought for each client is what you're solving for
so C. number of shares remaining to be sold
if 95,000 shares available before sale, 75,000 after, 20,000 were sold.
20,000 shared among 250 people is 80 shares each.
Answer:
C. the number of shares remaining after the stockbroker buys shares for her customers
Step-by-step explanation:
Here Most important variable is asked, So Option (C) is the best choice. It is the most important variable for finding the number of shares the company has left.
Option (A) can't be chosen because it is comparatively less important than option (C).
Option (B) never can be an important variable since the price of shares is not given.
Also, The number of shares the company has left after stockbroker's purchase = 95000 - 150×250 = 57500.
