Answer:
SP = 627 Rs
Step-by-step explanation:
Percentage loss is calculated as
, then
= 5% = 0.05 ( multiply both sides by 660 )
660 - SP = 33 ( subtract 660 from both sides )
- SP = - 627 ( multiply both sides by - 1 )
SP = 627 Rs
The first step in solving a problem is illustrating it just as what the picture shows. The ladder represents the hypotenuse, or the longest side of the right triangle. It measures 14 feet. The base measures 6 feet. The height of the top of the ladder from the base of the wall is denoted as x. Since this is a right triangle, the special equations for Pythagorean theorems would apply. The equation is
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the other shorter legs. Substituting the values,
14^2 = 6^2 + x^2
x^2 = 14^2 - 6^2
x^2 = 160
x = 4√10 = 12.65 feet
Answer:
2x^3 + 9 (if you meant the x to be multiplication)
2x^3 + 9x (if you meant the x to be a variable)

Answer:
x = -15
Step-by-step explanation:
Step 1: Write equation
3(2x - 5) - 3(x - 7) = 2x - 9
Step 2: Distribute
6x - 15 - 3x + 21 = 2x - 9
Step 3: Combine like terms
3x + 6 = 2x - 9
Step 4: Subtract 2x on both sides
x + 6 = -9
Step 5: Subtract 6 on both sides
x = -15
