Jim was thinking of a number. Jim adds 20 to it, then doubles it and gets an answer of 99.2. What was the original number?
azamat

Alright, lets get started.

Jim was thinking of a number.

Suppose the number Jim was thinking, is x.

Jim adds 20 to it means number will be = x+20

And Jim doubles it, means 2*(x+20)

Jim gets 99.2 and as per us, he gets 2*(x+20)

So, making them equal

2(x+20)=99.2

2x+40=99.2

Subtracting 40 in both sides

2x+40-40=99.2-40

2x=59.2

x=29.6

It means the original number is 29.6.   :   Answer

Hope it will help :)

Answer:

If 50.24cm = Circumference

Radius = 8cm

If 50.24cm^2 = Area

Radius = 4cm

Step-by-step explanation:

50.24cm what? Circumference? Area?

π = 3.14

2πr = Circumference

50.24 / 2π = r

r = 8

πr^2 = Area

50.24 / π = r^2

r^2 = 16

r = 4

There is a total of 45 boys and girls in a choir.
rusak2 [61]

Answer:

16.5 year

Step-by-step explanation:

Using, mean = sum/no. *of observations

Here,

=> 16.2 = (sum of ages of boys)/18

=> 16.2 x 18 = sum of ages of boys

=> 291.6 = sum of ages of boys

Similarly, sum of ages of girls = 27 x 16.7 = 450.9

Mean(total) = (sumof agesof boys + girls)/45

Mean = (291.6 + 450.9)/45 = 16.5

Find the equation of the straight line passing through the point (3, 3) which is perpendicular to the line y=-x-4​
Elena L [17]
Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x
