John is 4 years younger than twice Michael's age. Michael is John's younger brother. John is 18 years old. How old is Michael? Choose the equation that represents the situation.
Answers
Answer:
18=2m-4
Step-by-step explanation:
18 is the age of John. M represents the age of Michael. John is older than Michael so instead of 18=4-2m it is 18=2m-4. If you do 8=4-2m it will be inccorect because it will give you a negative. Michael is 11 years old.

The length and breadth of a rectangle are 80cm and 15cm .find its perimeter and area of the rectangle
Answers
• Length of the rectangle = 80 cm
• Breadth of the rectangle = 15 cm.
To find :• perimeter and Area of the rectangle .
Solution :As we know that:
• perimeter of the rectangle = 2 ( l + b)
=> perimeter = 2 ( 80 + 15)
=> perimeter = 2 ( 95 )
=> perimeter = 190 cm .
• Area of the rectangle = l×b
=> Area = (80×15)
=> Area = 1200 cm² .
Hence , the perimeter of the rectangle is 190 cm and Area us 1200 cm².
I hope it will help you.

Ariel earns the same amount each week from tutoring. When she started this job, she had $100 in her savings account. The table shows Ariel's savings account balance for her first month of work.
let x represent the number of weeks Ariel has been working and let y represent Ariel's account balance. Which equation, expressed in Slope-Intercept Form, represents the amount of money in Ariel's bank account over time?
A. y=350x - 100
B. y=350x + 100
C. y=100x - 350
D. y= 100x + 350
Answers
Answer:
B
Step-by-step explanation:
The required line is y = 350x + 100 expressed in slope-Intercept form, which represents the amount of money in Ariel's bank account over time.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
Let x represent the number of weeks Ariel has been working and let y represent Ariel's account balance.
As per the given table, take two points (0, 100) and (4, 1500)
This means that the line passes through points (0, 100) and (4, 1500).
Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
x₁ = 0, y₁ = 100
x₂ = 4, y₂ = 1500
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Substitute values in the equation, we get
⇒ y - 100 = (1500 - 100)/(4 -0 )[x -0]
⇒ y - 100 = (1400/ 4)x
⇒ y - 100 = 350x
⇒ y = 350x + 100
Hence, the required line is y = 350x + 100 expressed in slope-Intercept form, which represents the amount of money in Ariel's bank account over time.

Halima wants to cover all of the wall with tiles. The tiles are squares with sides of length 20 cm. The tiles are sold in packs. There are 10 tiles in each pack. Each pack of tiles costs £34.99 Halima only has £1000. How much would it cost Halima to tile the whole wall?
Length of the wall = 3m
Width of the wall = 4m
Answer:
£1049.70
Step-by-step explanation:
100cm = 1m
1 tile = 20cm
100cm÷ 20cm = 5
1m = 5 tiles
Width = 4m = 4 × 5 = 20 tiles
Length = 3m = 3 × 5 = 15 tiles
Total tiles needed = 20 tiles × 15 tiles = 300 tiles
Remember: 1 pack contains 10 tiles
10 tiles = 1 pack
300 tiles = 300/10= 30 packs
Note: 1pack costs £34.99
30 packs = 30 × £34.99= £1049.70
Halima needs £1049.70 to cover the wall with tiles
