Answer:
F =
Step-by-step explanation:
Given
C = ( multiply both sides by 9 )
9C = 5(F - 32) ← distribute
9C = 5F - 160 ( add 160 to both sides )
9C + 160 = 5F ( divide both sides by 5 )
= F
Answer:
y = 16
Step-by-step explanation:
if x =10 then y =320
that means y= 32x
so if x = 1/2
y = 32*1/2
y= 16
Answer:
Let Jody's Age be X
Then Jody's Brother age is: 2x - 3
Total is: (2x - 3) + x = 30
Now we solve for x
2x - 3+ x = 30
3x - 3 = 30
3x = 30 + 3
3x = 33
x = 33/3
x = 11
Therefore the age of Jody's Brother is (2×11) - 3 = 19
these are the answers ( i just did this and got it right)
1) Ionic radii tend to increase down a group.
4) Cationic radii tend to decrease across a period.
5) Ionic radii increase when switching from cations to anions in a period.
