Each pair of numbers in the table is related by the same function rule. That rule is: multiple each input number value by 3 to find each output number value. You can use a rule like this to find other values for this function, too
Answer:
x = -7
Step-by-step explanation:
First, expand right side
5 - x = 3x + 33
Move x to one side and constants to other side
5 - 33 = 3x + x
-28 = 4x
Divide both sides by 4
x= -7
The answer for the picture would be 21
1.19 - 19%
Factorize
(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0
Solve both for n
3n + 8 = 0
3n = -8
n = -8/3
3n - 8 = 0
3n = 8
n = 8/3
Therefore n = -8/3 and n = 8/3
A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18
a+b = 12 + 18 = 30
