Answer:
36
Step-by-step explanation:
Let the digits of the number be represented by t for the tens digit and u for the units digit.
u = 2t . . . . . . . . the units digit is twice the tens digit
2(10t +u) = (10u +t) +9 . . . . . double the number is 9 more than its reverse
Substituting for u, we have ...
2(10t +2t) = 10(2t) +t +9
24t = 21t +9 . . . . . . . . . . . collect terms
3t = 9 . . . . . . . . . . . . . subtract 21t
t = 3 . . . . . . . . . . . divide by 3
u = 2t = 6 . . . . find u
The number is 36.
Answer:
20
Step-by-step explanation:
Vertical angles are always equal to each other. So the answer is
3x + 4 = 73 - 9 Are you sure this is what the question is?
3x + 4 = 64 Subtract 4 from both sides
<u> -4 -4</u>
3x = 60 Divide by 3
3x/3 = 60/3
x = 20
I think it May be b because it’s slope is rising by two
