The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is = x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27 ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y
9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4
x=5-y
x=5-4=1
The number is: 10x+y=10(1)+4=14
Answer: the number is 14
I believe the correct answer is 151
Answer:
Point A is located at (-3.6, -4.5)
Step-by-step explanation:
Answer:
-64/33
Step-by-step explanation:
-5 1/3 / 2 3/4
-16/3 / 11/4
-16/3 * 4/11
-64/33
5x + 4 < 29
5x < 29 - 4
5x < 25
x < 25/5
x < 5
solution set is { 3,4 }
