It will have 15 protons because the atomic number will always equal the number of protons and vice versa
Regular= 3/5 equivalent= 6/10 just multiply the top and bottom by the same number.
Answer:
32
Step-by-step explanation:
First, combine like terms
4x+7=6x-9
+9 +9
4x+16=-9
-16 -16
Then divide by four to isolate x
4x=-25
x=-6.25
Plug in X to get the angle measure .
Step-by-step explanation:
3x + 5 = 36
3x = 36 - 5 = 31 (subtract 5 on both sides)
3x = 31
x = 31/3 (divide 3 on both sides)
Hence x = 31/3.
C
Because 1 km is 1,000 meters so you were just multiply 1000 by 10 and get 10,000
