The correct response is X=25
Answer:
-3x-7
Step-by-step explanation:
-3x and -6 aren't like terms, and neither are -3x and -1, so you leave -3x alone. You can combine -6 and -1. You simply add them as if they aren't negative and keep the negative sign. This results in -3x-7
Answer:
x = 7 x = -1
Step-by-step explanation:
3|x − 3| + 2 = 14
Subtract 2 from each side
3|x − 3| + 2 -2= 14-2
3|x − 3| = 12
Divide by 3
3|x − 3| /3 = 12/3
|x − 3| = 4
Now the absolute value has a positive and negative solution.
x-3 = 4 x-3 = -4
Add 3 to each side
x-3+3 = 4+3 x-3+3 = -4+3
x = 7 x = -1
Answer:
Step-by-step explanation:
Given: An angle measures 51 degrees
To find: fraction of a circle by which the angle turn
Solution:
Angle at the centre in a circle is equal to one complete angle i.e., 
Measure of an angle 
Therefore,
Fraction of a circle by which the angle turn = Measure of an angle/ Angle at the centre in a circle 
C=135+120+165+x+125+165+90=800+x= 900(all interior angles in heptagon)
900-800=100
x=100
d=100+90+x+95+90=375+x= 540(all interior angles in a pentagon)
540-375=165
x=165
