What is 3x plus 15 equals 60?
3x + 15 = 603x = 60 - 153x = 45x = 45/3Therefore, x = 15.
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
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

What is 12x-60 plus 6 equals 1x plus 9 plus 2x?
False12x - 66 = 3x + 912x - 3x = 9 + 669x = 65x = 7.22Check:12(7.22) - 60 + 6 = 1(7.22) + 9 + 2(7.22)86.64 - 66 = 7.22 + 9 + 14.4420.64 = 30.66
If the three angles of the triangle are given below find the value of x angle 1 equals 5x angle 2 equals 3x angle 3 equals x?
Since the internal angles of a triangle always add up to 180... 180=5x+3x+x is the same as 180=9x - therefore 180 divided by 9 equals 20. The three angles are 100, 60 and 20 degrees respectively.
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.
3x2 plus 3x minus 60?
the answer is -174
