The measure of the supplementary of an angle is 60 less than three times the measure of an angle?
Two supplementary angles add up to 180 degrees. If one of the angles is x degrees, then the other angle will be 3x - 60. So we have: x + 3x - 60 = 180 4x - 60 + 60 = 180 + 60 4x = 240 4x/4 = 240/4 x = 60 3x - 60 = 3(60) - 60 = 120 Thus, the angles have measures of 60 and 120 degrees.
What number is the difference of 9 and three times a number equals 69. Find the number?
the number = -20Let = the number3 times a number = 3 * x or 3xdifference of 9 and 3 times a number = 9 - 3xdifference of 9 and three times a number equals 69: 9 - 3x = 699 - 3x = 699 - 3x - 9 = 69 - 9-3x = 60-3x/-3 = 60/-3x = -20
If the perimeter is 60 feet on a triangle with sides in the ratio of 3 4 5 what is the length of the longest side?
3x + 4x + 5x = 60 feet 12x = 60 x = 5 The longest side is 5x therefore it is 25 feet. That means that the other sides are 4x (20 feet) and 3x (15 feet). 25 + 20 + 15 = 60
Which expression is equivalent to 3x + 3x + 3x?
3x + 3x + 3x = 3* (3x) = 9x
How do you do (3x 4)2?
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.

3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
What is the answer 3x divided 5-x divided 3 equals 4?
3x/(5-x)/3=4 3x/(5-x)=4X3 3x=12(5-x) 3x=60-12x 3x+12x=60 x=4
