Answer:
<h2>y = -4x</h2>
Step-by-step explanation:
Solve 20x + 5y = for y
20x + 5y = 0
subtract 20x both sides
5y = -20x
simplify:
y = <u>-20x</u>
5
finally
y = -4x
Answer:
x = 20°
Step-by-step explanation:
The angle opposite to 3x + 20 is also 3x + 20 (opposite interior angles)
The angle opposite to 5x is also 5x (opposite interior angles)
Solve:
Set up the equation by adding all the angles. The sum of these angles should equal 360.
- (3x + 20) + (3x + 20) + (5x) + (5x) = 360
- 16x + 40 = 360
- 16x = 320
- x = 20
x = 20°

Answer:
I don’t know much about the second part but the number 3 is being multiplied by is 7. 3x7=21, and than you add 5 giving you 26. Ohhhh now I see the equation is 3 times x+5=26.
Step-by-step explanation:
Hope this helps.
Answer:
x = 3
Step-by-step explanation:
5x - 2 = 3x + 4
2x = 6
x = 3
