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

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

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.

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.

William has a sticker album. Some pages have 1 sticker on them, and other pages have 2 stickers on them. If William has 18 stickers, how many different ways can he put the stickers in the album?
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
