Manuela works at least 22 hours in a week.
Step-by-step explanation:
Given,
Per hour salary of Manuela = $15
Amount deducted = $125
Amount received = $205
Let,
x be the number of hours per week.
Per hour salary * Number of weeks - Amount deducted ≥ Amount received
[tex]15x-125\geq 205\\15x\geq 205+125\\15x\geq 330[/tex]
Dividing both sides by 15
[tex]\frac{15x}{15}\geq \frac{330}{15}\\x\geq 22[/tex]
Manuela works at least 22 hours in a week.

For what value of x is the rational expression below equal to zero?
X-4/x-6
Answer:
Step-by-step explanation:
When x equals to 4
4-4 = 0
-------------
4-6 = -2
0/-2 = 0
The rational expression X-4/x-6 equals zero when X equals 4, as long as the denominator is not zero, which avoids division by zero.
The question asks: For what value of x is the rational expression below equal to zero? The expression given is X-4/x-6. To find when this expression is equal to zero, we need to understand that a rational expression equals zero when its numerator is zero (and the denominator is not zero, to avoid division by zero).
To solve X-4 = 0, we simply add 4 to both sides of the equation, getting X = 4. This means that the rational expression is equal to zero when X equals 4, given that X is not equal to 6 to avoid making the denominator zero, which would be undefined. Hence, the value of X that satisfies the condition is 4.

Solve for y.
2(-4y + x) = 4
Answer:
Step-by-step explanation:
-4y + X = 2
-4y = 2 - x
y = 2 - x/ -4
hope this helps!!
The value of y in terms of x is -1/2 + x/4.
To solve for y, we start with the equation 2(-4y + x) = 4.
Distribute the 2 inside the parentheses: -8y + 2x = 4.
Move the term with x over to the other side by subtracting 2x from both sides: -8y = 4 - 2x.
Isolate the y by dividing both sides by -8: y = (4 - 2x) / -8.
Simplify the right side by dividing both terms by -8: y = -1/2 + x/4.

-2 square root 20- square root 125
Answer:-5.93958251....
Step-by-step explanation:
To simplify the expression -2√20 - √125, we first factored the square roots, realizing that √20 equals 2√5 and √125 equals 5√5. Plugging these back into the equation, we then combined like terms to get the final answer of -9√5.
The question asks to simplify the expression -2√20 - √125.
First, let's simplify the square roots by factoring out squares from under the radical:
√20 = √(4×5) = √4√5 = 2√5√125 = √(25×5) = √25√5 = 5√5Now let's substitute these simplified forms back into the original equation and simplify:
-2(2√5) - 5√5 = -4√5 - 5√5
Combine like terms to get the final simplified result:
-9√5

What is wrong with this solution?
-5m - 16 = 19
5m - 16 + 16 = 19 + 16
Step One:
Step Two:
Solution:
m = 7
Final answer:
The solution shown is incorrect because the equation is not simplified before performing operations.
Explanation:
The solution shown is incorrect. Let's go step by step to find the error:
Step One: -5m - 16 = 19
Step Two: 5m - 16 + 16 = 19 + 16
Step Three: 5m = 35
Step Four: Divide both sides by 5: m = 7
The mistake in the solution occurs in Step Two. The previous equation should be simplified to 5m = 35 before dividing by 5. The addition of 16 on both sides should be taken care of first by canceling it out, resulting in 5m = 35 instead of 5m + 0 = 35.
Therefore, the correct solution is m = 7.
Final answer:
The solution to the equation -5m - 16 = 19 is m = -7, not m = 7. The student initially misplaced the sign after dividing by -5.
Explanation:
The student has made a mistake in the initial steps of solving the equation -5m - 16 = 19. The correction process involves isolating the variable m on one side of the equation to find its value.
Step One
Add 16 to both sides of the equation to eliminate the -16:
-5m - 16 + 16 = 19 + 16
-5m = 35
Step Two
Divide both sides by -5 to solve for m:
-5m / -5 = 35 / -5
m = -7
The correct solution is m = -7, not m = 7. It is important to follow the addition rules and subtraction rules carefully and to remember to divide by the coefficient of m, which in this case is -5, resulting in changing the sign of the solution.
