t When you reverse the digitals in a certain number you increase its value by 27. Find the number if the sum fixes digits is 9.
TiliK225 [7]
The number=10x+y
we suggest this system of equations:
(10y+x)-(10x+y)=27
x+y=9                                ⇒x=9-y

Can solve this system of equations by susbstitution method.
(10y+(9-y)-(10(9-y)+y)=27
10y+9-y-(90-10y+y)=27
10y-y+10y-y=27-9+90
18y=108
y=108/18
y=6

x=9-y
x=9-6
x=3

The number=10x+y=10(3)+6=36

Answer: the number is 36.

to check:
63-36=27
6+3=9

The sum of the two 5 digit numbers ABC10 + ABC12 is 123422. What is A + B + C?
Evgesh-ka [11]

Answer:

14

Step-by-step explanation:

We are given with two 5\ digit numbers whose first 3 \ digits are same.

It is given that their sum is 123422

adding the last two corresponding digits gives,

0+2=2\\1+1=2

Now adding the rest,

C+C \ should\ be\ 14 to get 4

1 \ carries\\B+B should not give anything to carry as that will make A in decimal to satisfy the addition.

Therefore,

B+B \ has \ to \ be 1+1=2,+ 1 \ carry=3

Thus B= 1

And finally,

A+A=12\\A=6

Thus A=6, B=1 \ and \ C=7

Now simplifying

A+B+C\\=6+1+7\\=14

Thus 14 is the answer.

How do you find the median on a dot plot
Andrei [34K]
On the dot plot you would find the numbers, put them in order lowest to highest and either you can take a pencil and mark them out or take your two index fingers and cross the out to see what is in the middle. If there is two numbers then you add them together and divide them then that is the median.

One cookie and two brownies cost the same as two cookies and one brownie. One cookie and one brownie together cost $1. What is t
adoni [48]

Answer:

50 cents

Step-by-step explanation:

Let's set up a system of equations. Let x be a cookie and y be a brownie then...

x+2y=2x+y

x+y=1

We can solve this using substitution

x=1-y

1-y+2y=2(1-y)+y

1+y=2-2y+y

1+y=2-y

-1=-2y

y=1/2

One brownie costs 50 cents and one cookie costs...

x+1/2=1

x=1/2

One cookie costs 50 cents
