1-10x = 81 -10x = 81-1 -10x = 80 x = -8
what must you do to make the equation 81 X 9 equals 801 true.
Eighty one inches equals 6 feet 9 inches.
1 times 81 3 times 27 9 times 9
81 x 81 = 6561
The problem '3x+9=81-5' can be solved as follows - 3x+9=81-5x Original Problem 3x=72-5x Subtract 9 from both sides of the equation 8x=72 Add '5x' to both sides of the equation x=9 Divide both sides by 8
An equation where y = 81
no because it has an equal symbol in it
9x9=81
x2 = 81 Square root both sides:- x = +/- 9
what must you do to make the equation 81 X 9 equals 801 true.
There are several combinations that could equal 81 when subtracted. For example, 100 - 19 = 81, or 90 - 9 = 81.
Using the discriminant the possible values of k are -9 or 9
81 centimeters is equal to 31.8897638 inches.
x*x*x=y
One square yard equals 9 square feet, so 9 sq. yds. would equal 81 sq. ft.
The expression is likely 4x2 - 36x +81 which is the same as (2x - 9)(2x - 9) or (2x - 9)2
Eighty one inches equals 6 feet 9 inches.
