Answer:
b = 7
Step-by-step explanation:
6 b + 6 = 48
Subtract 6 from each side
6b+6-6 = 48 -6
6b = 42
Divide each side by 6
6b/6 = 42/6
b = 7
Answer:
5n
Step-by-step explanation:
output=5x
where x is = input
there fore if input is n, output is 5n
Y2-y1
--------
x2-x1
7+3 =10
----- ---
5+6 =11
Depends on the question but you generally must use a variety of operations to isolate the variable by itself on one side of the equation
61 + 86 = 147
180 - 147 = 33
x = 33
the interior sum of angles is equal to 180 , in order to find x you would use the already established values of two corners and find the missing value
