3x-132=0
you need to add all like terms first then answer the equation
Answer:
x=15
Step-by-step explanation:
5x+(180-9x)+(180-8x)=180
total of a triangle angles is 180
David sold 60 bottles and Sammy sold 100 bottles. x(5+3)=160; 5x+3x=160; 8x=160; 8x/8=160/8; x=20; 20(5+30); 100+60=160
Answer:
n/4-6
Step-by-step explanation:
n/4-6
This is the expression because we need to divide n by 4 and subtract 6
The number is 68
68 divided by 4= 17
17-6=11
The roots are-4 and 7y=x² - 3x - 28<span>The roots are
-9 and 2</span>x² = 18 - 7xThe roots are-4,and 2y = x² + 2x -8The roots are-8 and 10x² - 2x - 6 = 74<span>The roots are
-15 and-1</span>x² + 15 = - 16xThe roots are-5 and 9y=x² - 4x - 45<span>The roots are
4 and 14</span>x² - x + 56 = 17x<span>The roots are
2 and 27</span>x² - 29x = - 54
