Answer:
(-2y+5x) / (3x - 2y)
Step-by-step explanation:
If we write this sentence, we have:
((-2/x) + (5/y)) / ((3/y) - (2/x))
If we do LCM in the denominators of each fraction, we have:
((-2y+5x)/xy) / ((3x - 2y)/xy)
We can cut the 'xy' in the numerator and denominator of the whole fraction:
(-2y+5x) / (3x - 2y)
The final expression we have is (-2y+5x) / (3x - 2y)

Find the value of \(n\) such that the equation \(x^2-n=0\) has 24 and -24 as solutions.
Answer:
The value is 576.
Step-by-step explanation:
24x24=576 (positive or negative 24)
\(x^{2}\)-n=0
\(x^{2}\)-576=0
Add 576 to both sides.
\(x^{2}\)=576
\(\sqrt{x^{2} }\)=\(\sqrt{576}\) Find Square Root.
x=±24 It's True!
To the nearest square meter, what is the curved surface area of the half pipe if it’s 7 m long?
The radius is 2.5 m
Answer: 55 m²
Step-by-step explanation:
The arc length of a half-circle is πr, so the area of the curved surface is A = πrl = π(2.5 m)(7 m) = 17.5π m² ≈ 55 m²

I have 60% on my iPad and my brother has 90% on his how much more percentage I need as a fraction.
Answer:
1/3
Step-by-step explanation:
just convert it?
3/10
Step-by-step explanation:
60% is the same as 60/100
90% is the same as 90/100
90-60=30
30/100
30/100 is divided by 10 on each side to simplify it to 3/10

Step-by-step explanation:
QUESTION 7:
We are trying to find angles 1 and 2.
Known angle: 107˚.
In this question, we have 2 parallel lines with a transversal. A transversal is a line that passes through 2 parallel lines making it so that the angles on both sides are exactly the same.
Step 1: Find the measures of all the angles using the one we already know.
I will start with the angle adjacent (right next to) the angle that measures 107˚. As you can see, it is a supplementary angle because both of them form a straight line, or 180˚.
Therefore,
107+x= 180
x= 180-107
x= 73˚
Next, I will find the measure of the angle that is vertical to the one that measures 107˚. Note that angles that are vertical to each other are always identical, or in other words they have the same measure. Hence, the angle "vertical", or opposite to the one that measures 107˚ has to measure 107˚ as well. You can also tell this is true because they look the same.
Now I'll find the measure of the angle vertical to the one that measures 73˚. As we know, vertical angles are identical, so the one vertical to it is 73˚.
Here, I'll solve for angles 1 and 2. Like I said earlier, when a transversal crosses through 2 parallel lines, there will be 2 sets of angles that all have the same measurements.
To solve for angle 1, simply know what angle is right below it, and that is the one that measures 107˚. (If you look at the 2 lines, you will see that both angle sets are essentially duplicates of each other.) Likewise, angle 2 has to be 73˚ because the one under it is also 73˚.
Angle 1: 107˚
Angle 2: 73˚
QUESTION 8:
Again, we have a transversal that passes through 2 parallel lines. One angle measures 95˚. When there are 3 seperate angles along a straight line, the one next to the one with the given measurement will be the same as that one.
So angle 3 is 95˚. To find angle 4, find the angle measurement that's vertical to angle 3, which is 95˚. Now, since that angle and angle 4 are supplementary (both form a straight line which is always 180˚), 95+x= 180.
(x stands for angle 4)
x+95= 180
x= 180-95
x= 85
Angle 4= 85˚.
QUESTION 9:
ANGLE 5: 49˚
When there is a transversal, there are 2 identical pairs of angles. Therefore, angle 5 must be 49˚.
ANGLE 6: 131˚
angle 5 and angle 6 form a straight line which means they are supplementary angles. Therefore, both angles must add up to 180˚. So 49+x= 180
x= 180-49= 131
(x stands for angle 6)

is 50.24 and 50.23 rational or irrational numbers pls explain pls pls
its easy i know but my brain hurts
Answer:
50.23 and 50.24 are both rational numbers.
Step-by-step explanation:
Rational numbers can be written like a ratio.
●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.
●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)
●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.
50.23
= 50 + 23/100
= 50•(100/100) + 23/100
= 5000/100 + 23/100
= 5023/100
50.23 is equal to 5023/100.
50.24 = 5024/100 = 2512/50 = 1256/25
Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)
Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

The approximate weights of the two animals are 5.12 x 102 lbs. and 6.8 x 102 lbs. Find the total weight of the two animals. Write the final answer in scientific notation with the correct number of significant digits. Can you please help me and stop deleting my question :(
these are the answers
1.2 x 103 lbs.
1.19 x 103 lbs.
11 x 102 lbs.
5.8 x 102 lb
Answer: Option A is the correct answer
Step-by-step explanation: I took the test and got it right
The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.
Given approximate weights of the two animals are as:
1. 5.12 x 10² lbs
2. 6.8 x 10² lbs
We need to find the total weight of the two animals.
Step 1: Add the weights together:
5.12 x 10² lbs + 6.8 x 10² lbs
Step 2: Perform the addition:
(5.12 + 6.8) x 10² lbs
11.92 x 10² lbs
Step 3: Express the result in scientific notation with the correct number of significant digits:
The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:
11.9 x 10² lbs
This matches option 2 from your provided answers:
2. 1.19 x 10³ lbs.
So, the correct answer is: 1.19 x 10³ lbs.

Answer:
1. 2(n−3)=4n+1 2 ( n - 3 ) = 4 n + 1. Simplify 2(n−3) 2 ( n - 3 ) . 2n+2⋅−3=4n+1 2 n + 2 ⋅ - 3 = 4 n + 1
2. x 2^(x-1)=10. 2x−1=10 2 x - 1 = 10
Step-by-step explanation:
1 ) n = -1/4
2 ) x = 3/5
Step-by-step explanation:First equation:
1/2 = n + 3/4
Step 1 - Flip the equation:
n + 3/4 = 1/2
Step 2 - Subtract 3/4 from both sides:
n + 3/4 - 3/4 = 1/2 - 3/4 =
n = -1/4
Answer: n = -1/4
Second equation:
x - 1/2 = 1/10
Step 1 - Simplify both sides of the equation:
x + -1/2 = 1/10
Step 2 - Add 1/2 to both sides:
x + -1/2 + 1/2 = 1/10 + 1/2
x = 3/5
Answer: x = 3/5
