Answer:
Ali 25
Beth 15
Clare 32
Step-by-step explanation:
Here, we want to get the score of the three
let Ali’s score be x
He scored 10
more than Beth; Beth score will be x-10
Let us now work with the ratio
x/x-10 = 5/3
3x = 5(x-10)
3x = 5x - 50
5x-3x = 50
2x = 50
x =
50/2
x = 25
Beth will
score 25-10 = 15
score had 7 more than Ali,
25 + 7 = 32
Please help ASAP Which equation represents the function graphed
on the
coordinate plane?
Answer:
g(x) = |x + 4| - 2
I recommend next time you try substituting the x-values from points the line meets into each function until g(x) matches the y-value. For example, the line/function passes through the point (1, 3). Substitute the x-value: 1 into the function where it says x. That would give you 3 = |1 + 4| - 2. (If you're wondering where I got 3 from g(x) is basically the same as y. Simplify the values in the "||" first. You should then get 3 = 5 - 2. Simplify that and you get 3 = 3 which means g(x) = |x + 4| - 2 is the correct answer. If you were to get anything else other than 3 such as "3 = 4", it would not be correct.

180-71 = 109 degrees
X = 25 -3y and 4x + 5y = 9
What are the solutions
Answer:
x=-14, y=13
Step-by-step explanation:
4x+5y=9
x+3y=25
4x+5y=9
-4x-12y=-100
-7y=-91
y=13
Subsitute: x+3(13)=25
x=-14
I need the solution. Please give steps
y = 10x + 20
y = 20x + 10
Answer:
If your trying to answer for X, here is how you do it.
For the equation '' Y = 10x + 20 '', isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:
X = Y/10 − 2
Or
X = [tex]\frac{Y}{10}[/tex] − 2
For the other equation " Y = 20x + 10 ", it's the exact same thing. Isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:
X = Y/20 − 1/2
Or
X = [tex]\frac{Y}{20}[/tex] − [tex]\frac{1}{2}[/tex]
Id.k uhhhh

Rewrite as a simplified fraction. \large{0.\overline{23} = {?}}0. 23
Answer:
23/100
Step-by-step explanation:
Given the decimal value 0.23, to write as a fraction;
0.23 = 23/100
The place value of dot will be replaced as 1 at the denominator and since the decimal is in 2 decimal places, two zeros will be added to after the 1 to make it 10 thereby making the required fraction 23/100. Hence the value of 0.23 as a fraction will be 23/100

Four chords are drawn in the figure below, creating a quadrilateral with every vertex on the circle.
Using the special properties of this figure, determine m
Answer:
21°
Step-by-step explanation:
<DCB = 3x + 8°
< DAB = 5x + 4°
Now
<DCB + <DAB = 180° { being opposite angles of cyclic quadrilateral }
3x + 8° + 5x + 4° = 180°
8x + 12° = 180°
8x = 180° - 12°
8x = 168°
x = 168° / 8
Therefore x = 21°

Paul invests £150 in a bank account paying 2% interest per annum for 10 years. Work out how much money he has in the account at the end of the 10 years
Answer: £180
Step-by-step explanation:
The interest gotten for the 10 years will be calculated as:
= Principal × Rate × Time
= 150 × 2% × 10
= 150 × 0.02 × 10
= 30
The amount he has in the bank account at the end of the 10 year will be:
= Principal + Interest
= £150 + £30
= £180
Which best describes the composition of transformations that maps ΔLMN to ΔL'M'N?
Answer:
a
Step-by-step explanation:
its A
Option C us correct, (D₂oR x-axis)(ΔLMN) best describes the composition of transformations that maps ΔLMN to ΔL'M'N
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
We have to find the composition of transformations that maps ΔLMN to ΔL'M'N.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
Graph transformation is the process by which a graph is modified to give a variation of the proceeding graph.
The graphs can be translated or moved about the xy-plane.
A translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis.
As we observe the graph dilation and reflection applied to triangle LMN to get triangle L'M'N'.
A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.
(D₂oR x-axis)(ΔLMN) is the transformations that maps ΔLMN to ΔL'M'N.
Hence, Option C us correct, (D₂oR x-axis)(ΔLMN) is the transformations that maps ΔLMN to ΔL'M'N.

Tessa bought stock in a restaurant for $277.00. Her stock is now worth $346.25. What is the percentage increase of the value of Tessa's stock?
Answer:
125%
Step-by-step explanation:
Divide 346.25 by 277
you get 1.25
multiply it by 100
Answer:
25%
Step-by-step explanation:
This is calculated this way:
$346.25/$277 = 1.25
Then subtract 1, because that part represents what Tessa had to start with. That leaves
0.25
That decimal equals 25%, and that is the answer.

Answer:
6 ways
Step-by-step explanation:
William has a sticker album.
We are told in the question that:
Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers
The many different ways that can he put the stickers in the album is calculated as:
18 stickers ÷ ( 1 stickers + 2 stickers)
= 18 ÷ 3
= 6 ways
Therefore, the different ways that he can put the stickers in the album is 6 ways
