3x + 6 = 48 (alternate angles are equal)
- 6
3x. = 42
÷3
x = 14 degrees
180-48 - 2y + 5y-9 =180
123 + 3y = 180
-123
3y = 57
÷3
y = 19 degrees
Explanation:
To find the last angle on the top straight line, do:
180 - (the 2 given angles).
So, 180 - (3x + 16, which is 48 due to alternate angles being equal). Then, minus the 2y.
(180 - 48 - 2y) & simplify => 132 - 2y
This gives you the equation for the missing angle on our top straight line.
Thus, co-interior angles add to 180. So, we add the new equation (132 - 2y) to 5y - 9.
Simplify
=> 123 + 3y (because - 2+5 =3)
and put it equal to 180. Solve for y
Hope this helps!
Answer: ARE THEIR OPTIONS TO CHOSE FROM
Step-by-step explanation:
Good morning
Answer:
NO
Step-by-step explanation:
Here we just substitute x and y by their values and see if the inequality still true or not
y = 3
6x + 3 = 6(2) + 3 = 15
since 3 < 15 then the inequality y > 6x + 3 is wrong.

Answer:
A) 4x+3y=14
B) 3x-2y=2
We multiply equation A) by (2/3)
A) (8/3) x +2y = 28/3 then we add this to equation B)
B) 3x-2y=2
5 (2/3) x = 11 (1/3)
x = 2
A) 4 * 2 + 3 y = 14
A) 3y = 6
y = 2
