Answer:
<u>The number is 170</u>
Step-by-step explanation:
Let's solve for x, this way:
x = A number that decreased by 20% of itself, the result is 136
20% = 0.2
x - 0.2x = 136 (Like terms)
0.8x = 136
x = 136/0.8 (Dividing by 0.8 at both sides)
x = 170
Let's prove that x = 170 is correct
170 - 0.2 (170) = 136
170 - 34 = 136
136 = 136
We proved that x = 170 is correct
Answer:
Yeah it's option 4, you're right
Step-by-step explanation:

Answer:
16x-2 = 15x+5 (reason: corresponding angles are equal)
16x-15x-2 = 5
1x-2 = 5
1x = 5+2
1x = 7
x = 7
DEGREE MEASUREMENT OF 16x-2:
16(7)-2
= 112-2
= 110°
