Lines L and M are parallel. Therefore, angle 19x equals to the angle adjacent to angle 17x.
This means 19x + 17x = 180°
36x = 180°
x = 180°/36 = 5°
Hope that helps you :)
6x + 8 = 2x + 4
- 2x
4x + 8 = 4
- 8
4x = -4
÷ 4
x = -1
So the answer is B. -1. I hope this helps!
Answer:
x=75, y = 50
Step-by-step explanation:
Solve the following system:
{x + y = 125 | (equation 1)
5 x + 8 y = 775 | (equation 2)
Swap equation 1 with equation 2:
{5 x + 8 y = 775 | (equation 1)
x + y = 125 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 8 y = 775 | (equation 1)
0 x - (3 y)/5 = -30 | (equation 2)
Multiply equation 2 by -5/3:
{5 x + 8 y = 775 | (equation 1)
0 x+y = 50 | (equation 2)
Subtract 8 × (equation 2) from equation 1:
{5 x+0 y = 375 | (equation 1)
0 x+y = 50 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 75 | (equation 1)
0 x+y = 50 | (equation 2)
Collect results:
Answer: {x = 75
, y = 50
Answer:
A. 5th day B. Yes
Step-by-step explanation:
Ivy: 3,6,9,12,15
Cactus: 5,10,15,20,25
Right now that would be the 5th day. So yes, he will water them again in February.
I) 156 degrees
The exterior angle is 180-156
=24
The number of sides=
The number of sides= 15 sides
ii) 162 degrees
The exterior angle= 180-162
=18
The number of sides=
= 20 sides
