Answer:
by the -16 did you mean to put a + sign or is that a t
Answer:
The number is 27
Step-by-step explanation:
Let the 10s digit be x
Let the units digit be y
y = x + 5
10x + y = 3(x + y) Remove the brackets
10x + y = 3x + 3y Substitute the x + 5 into the second equation for y
10x + x + 5 = 3x + 3(x + 5) Remove the brackets on the right.
10x + x + 5 = 3x + 3x +15 Collect like terms on each side.
11x + 5 = 6x + 15 Subtract 5 from both sides
11x + 5 - 5 = 6x + 15 - 5 Collect like terms
11x = 6x + 10 Subtract 6x from both sides
11x - 6x = 6x - 6x + 10
5x = 10 Divide by 5
5x/5 = 10/5
x = 2
y = x + 5
y = 2 + 5
y = 7

lemme answer it,I'll put the answer at the comment section
It really depends on how precise you're going to get.
You could get away with only two parts, but to be really precise, you should probably divide it into twelve (12) parts, because 5/12 means five out of twelve parts, so its would be right on the fifth subdividing marker line.
