Answer:
n=-9
Step-by-step explanation:
Solution for -8-5n=64+3n equation: Simplifying -8 + -5n = 64 + 3n Solving -8 + -5n = 64 + 3n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3n' to each side of the equation. -8 + -5n + -3n = 64 + 3n + -3n Combine like terms: -5n + -3n = -8n -8 + -8n = 64 + 3n + -3n Combine like terms: 3n + -3n = 0 -8 + -8n = 64 + 0 -8 + -8n = 64 Add '8' to each side of the equation. -8 + 8 + -8n = 64 + 8 Combine like terms: -8 + 8 = 0 0 + -8n = 64 + 8
Answer:
A) 8x+40
Step-by-step explanation:
We know that one wall side is 5m.
To find the area of one wall, we do 5²=25m²
We know there is 4 walls. So we have to find total area of all four walls.
Which is 25×4=100m²
To find the total cost of white washing the room, we have to do:
100(total area)×23(cost per m²)=$2300
So the total cost of the area is $2300
Answer:
$142.95
Step-by-step explanation:
Given Original value of the sofa = $349
Rate of depreciation each year = 20%
Number of years = 4
To find the value of the sofa after 4 years use depreciation formula:
If the constant decrease in population be R% per annum. Then the population after n years is 
= 142.9504
= 142.95 (Nearest cent)
Hence, the value of sofa after 4 years is $142.95.
X/3 - 2 greater than or equal to -12
add two
x/3 is greater than or equal to -10
now multiply both sides by 3
x is greater than or equal to -30
