What is the unitary method?
The unitarymethod is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. The unitary method is a method by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
We are given the sum of 130 cm and 50 mm. in meters
130 cm = 130 / 100
= 1,3m
50 mm = 50 / 1000
= 0,05m
Therefore, the addition is;
1.3 + 0.05m = 1.35m

Answer: $45
Step-by-step explanation: Let the amount of money be x ,
Then , after Jamila spent $33 , the remaining money is x-33,
Also , after Akiko spent $42 , the remaining money is x- 42,
since Jamila is now having 4 times as much money left as Akiko, we have
x - 33 = 4 ( x - 42)
x - 33 = 4x - 168
-33+168 = 4x - x
135 = 3x
Therefore ,
x = 45

To find out the slope, we use a formula known as rise/run.
Rise means how high a point goes between any two points and run is how far the space is between any two points.
We can see that there are two points give to us. Now we ask our self how high do we have to go to reach the second points’ height. If we count it we go five UP. Meaning that the rise is positive 5.
Now we see how far the two points are. If we count it, we go 1 space the LEFT meaning -1 since going left on a graph means x is getting smaller.
Now that we have he two values, we put them into rise/run
5/-1=-5
So our value of m is -5
Meaning y=-5x+b
We still have our value of b to find and we can do this by choosing any one point on the graph and substituting it into the equation. We know that one of our points is (3,0)
We put these into the equation
y=-5x+b
0=-15+b
b=15
Therefore, y=-5x+15
