Answer:
the number of protons is equal to the number of electrons which in this case is 17.and the neuron number is the atomic number minus the number of protons,cause the nucleus comprises of both the neurons and protons
neurons=35-17=18
protons=17
electrons=17
I hope this helps
The answer can be 15 or -3. Hope that helped.
#1 (15)
50%= 1/2
1/2 of 30 is the same as 30÷2=15
#2 (20kg)
25%= 1/4
1/4 of 80 is the same as 80÷4= 20
#3 (30cm)
1/3 of 90 is the same as 90÷3=30
#4 (8m)
2/3 of 12 is the same as 12÷3= x2
12÷3= 4(2)= 8
#5 (70)
10% = 1/10
1/10 of 700 is the same as 700÷10= 70
#6 (280)
40%= 4/10
700÷10=x(4)
70(4)=280
#7 (2700 m)
9/10
3000÷10=x(9)
300(9)= 2700
Answer: see image
<u>Step-by-step explanation:</u>
Draw the line y = 1. Count how many units away the point is from that line. Move that point the same number of units in the opposite direction to create the reflection.
J is 2 units above y = 1. The new point is 2 units below y = 1. → (3, -1)
K is 3 units above y = 1. The new point is 3 units below y = 1. → (6, -2)
L is 5 units above y = 1. The new point is 5 units below y = 1. → (3, -4)
M is 3 units above y = 1. The new point is 3 units below y = 1. → (0, -2)
