Answer:
-2 > x
Step-by-step explanation:
14 <-7x
Divide each side by -7, remembering to flip the inequality
14/ -7 > -7x/-7
-2 > x

Hope this helps I’m pretty sure I’m right.
Answer:
4000
Step-by-step explanation:
divide 1.5% by 100 to remove the % symbol: 0.015
set you equation: 0.015x = 60
divide both sides by 0.015: x = 4000
Answer:
36
Step-by-step explanation:
Angles in a triangle sum to 180 degrees.
The angle in the bottom left will equal 180 - (3x + 6) as angles along a staight line also sum to 180 degrees.
180 - ( 3x + 6)
180 - 3x - 6 [expand bracket]
174 - 3x
Now we can add up all the angles and equate them to 180 to solve for x.
24 + 2x + 18 + 174 - 3x = 180
216 - x = 180
216 = 180 + x
x = 36
