Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = 
and tan60° = 
, then
sin60° = 
= 
= ( cross- multiply )
x = 4 ( divide both sides by )
x = 4
and
tan60° = 
= 
= ( multiply both sides by y )
y = 2 ( divide both sides by )
y = 2
Answer:
-1/2
Step-by-step explanation:
4x + 7 = 5
4x=5-7
4x=-2
x=-2/4
x=-1/2
hope this helps u!
Since a atom of chlorine has 36 fewer protons than an atom of iodine, then their total is 70.
So you have to subtract 36 from 70
70 - 36
= 34
*your answer is 34 protons for an atom of iodine
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
