Answer:7 that’s easy
Step-by-step explanation:
Answer:
Brother is 70.5 and sister is 64.5
Step-by-step explanation:
you will need to set up a simple equation and give out variables.
Girls age = 6-x
Brother's age= x
the you will take those 2 and add them and place them equal to 135:
6-x+x=135
6-2x+6=135+6
The 6 cancels out
2x=141
2x/2=141/2
x=70.5
The brother's age would be 70.5 then and the girl's would be 64.5

Square root of 169 by Prime factorization is 13×13
Y = 8x + 12
Now, plug in the 60.

Subtract 12 from both sides.
48 = 8x
Divide both sides by 8.
6 = x
Swap sides.
x = 6
