1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385

The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)

-b/-1= 0.5/-1
Therefore b=-0.5

The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10

Hence, c= 0.01

Identify the percent of change as an increase or a decrease. 9 points to 4 points
padilas [110]

Answer:

55.55% decrease

Step-by-step explanation:

change\% =  \frac{final \: point \:  - initial \: point}{initial \: point \: value}  \times 100

In the question ,

Initial point value = 9

Final point value = 4

Change% = \frac{4 - 9}{9}  \times 100 =  \frac{ - 5}{9} \times 100 =  - 55.55\%

Problem page the length of a rectangle is four times its width. if the perimeter of the rectangle is 70 cm , find its area.
agasfer [191]
So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.
