20\2=10
10\2=5
5\2=2.5
2.5\2=1.25
Answer:
answer below
Step-by-step explanation:
a is: 0.8
b is : 2
c is: 5
d is: 12.5
To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11
Answer:
-1/9 (x+27)
Step-by-step explanation:
Divide the whole expression by -1/9.
-1/9x becomes x
-3 becomes + 27
