X-y<0 add y to both sides
x<y or if you prefer
y>x
Answer:
x = 10
Step-by-step explanation:
3![3x(3+5x)=240\\9x+15x^{2} =240\\\\9x+\sqrt{15x^{2} } =240\\9x+15x=240\\24x=240\\x=10](https://tex.z-dn.net/?f=3x%283%2B5x%29%3D240%5C%5C9x%2B15x%5E%7B2%7D%20%3D240%5C%5C%5C%5C9x%2B%5Csqrt%7B15x%5E%7B2%7D%20%7D%20%3D240%5C%5C9x%2B15x%3D240%5C%5C24x%3D240%5C%5Cx%3D10)
Answer:
<em>(b). 27</em>
Step-by-step explanation:
The sum of exterior angles of any polygon is 360°
2x° +56° + 4x° + 57° + 85° = 360°
6x° + 198° = 360°
6x° = 360° - 198°
6x° = 162°
<em>x = 27</em>
Answer:
She worked a total of 9 1/4 hours
She still owes her uncle $5.90
Step-by-step explanation:
29.95/2.60
6+1 3/4+1 1/2
9.25*2.60= 24.05
29.95-24.05= 5.90
distance left to run = total distance - distance already run
= 3 miles - (13/7) miles
= 21/7 miles - 13/7 miles = 8/7 miles
