i need help with this question
Answer:
1) 9/20
2) 5/11
Step-by-step explanation:
For the first question: We read the number "0.45" as "45 hundredths," and we write it as the fraction 45/100. Of course, since 45 and 100 share the common factor 5, we can reduce this fraction by dividing the numerator and denominator by 5 to get the reduced form 9/20.
For our second problem, we need to perform a bit of "mathematical surgery" to find the appropriate fraction for x = 0.454545... First, the dots tell us that this fraction is repeating - those 45s will keep going on and on forever. When we multiply x by 100, then, we move the decimal two places to the right, but the repeating part still remains, giving us
[tex]100x=45.454545\dots[/tex]
From here, we can "surgically remove" the repeating bit using our original value of x:
[tex]100x-x=45.454545\dots-0.454545\dots\\99x=45[/tex]
And from here, we just have to divide both sides of the equation by 99 to solve for x:
[tex]99x=45\\x=45/99\\x=5/11[/tex]

Devon scored 18 points in the first basketball game but 22 in the second game. What’s the percent of change?
Answer:
22.22%
Step-by-step explanation:
Well first let's find the difference between 22 and 18. 22 - 18 = 4. There's a 4 point difference, so now we need to find out how much 4 is of 18. 4 is 22.22% of 18.

19 = 4р - 5
Can you also explain how to do it as well? Thank you!
Step-by-step explanation:
you move the 4p to the other side, making it negative,
- 4p + 19 = -5
then, you move the 19 to the other side, making it negative,
- 4p = -5 - 19
then you subtract,
- 4p = -24
divide by -4,
p = 6

Question: The graph shows a journey in a car. Which of the statements most likely describes the journey at the portion of the graph labeled J?
Answers:
1. The car continues its journey because the portion shows a linear function.
2. The car is waiting at the starting point because the portion shows a constant function.
3. The car is traveling the same distance per unit of time because the portion shows a linear function away from the starting point.
4. The car stops a distance away from the starting point because the portion shows a constant function away from the starting point.
Answer:
It is 2 because the Time (hr) is passing by and the distance did not change at all
3x + 8x +1 = 34 (Combine like terms)
x=
Answer:
x = 22
Step by step solution:
5x+(3x-18)+x=180
Simplifying
5x + (3x + -18) + x = 180
Reorder the terms:
5x + (-18 + 3x) + x = 180
Remove parenthesis around (-18 + 3x)
5x + -18 + 3x + x = 180
Reorder the terms:
-18 + 5x + 3x + x = 180
Combine like terms: 5x + 3x = 8x
-18 + 8x + x = 180
Combine like terms: 8x + x = 9x
-18 + 9x = 180
Solving
-18 + 9x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 9x = 180 + 18
Combine like terms: -18 + 18 = 0
0 + 9x = 180 + 18
9x = 180 + 18
Combine like terms: 180 + 18 = 198
9x = 198
Divide each side by '9'.
x = 22

Elsa took out a 2-year loan to buy a car at a 6% simple interest rate.
A. If she has to pay a total of $264 in interest, how much principal did she borrow to pay for the car?
B. How much did she end up paying for her car altogether?
Step-by-step explanation:
P = I / rt is the formula we're going to use.
P is the principle (which is what we're solving for)
I = the interest accrued over the specified amount of time (2 years)
r = the interest rate (6%)
t = the time specified (2 years)
Change the percent to a decimal. Place the decimal two places to the left to make 0.06.
P = 264 / 0.06(2)
P = 264 ÷ 0.12 = 2,200
Principal borrowed would be $2,200

The point (2, -7) is reflected across the x-axis.
What are the coordinates of the image of the point?
Answer: need more information
Step-by-step explanation: ....
The image of the point (2, -7) after reflection across the x-axis is (2, 7).
What is Reflection?In mathematics, reflection is a transformation that flips a figure over a line or plane. The line or plane is called the axis of reflection, and each point of the figure and its image are equidistant from the axis of reflection.
We have the coordinates as (2, -7).
Now, the rule for reflection across x- axis is
(x, y) -> (x, -y)
When a point is reflected across the x-axis, its y-coordinate is negated.
Therefore, the image of the point (2, -7) after reflection across the x-axis is (2, 7).
