Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40
Answer:
x = 198
Step-by-step explanation:
1/2x + 101 = 200.
Subtract 101 from both sides.
1/2x = 99
You want x by itself, therefore you have to get rid of 1/2. The opposite of diving by two, is multiplying by two.. therefore, you must multiply both sides by two.
x=99*2
x=198
-6 x 2 +5 = -7
The absolute value of -7 is 7.
8 x 1/2 =4
7-4=3
