The digits in the tens place of a two-digit number are 3 more than the digits in the unit place. If the digit at the unit place be ‘b', then the number is a) 11b + 30 b) 10b + 30 c) 11b + 3 d) 10b + 3

A

Step-by-step explanation:

We are told that the number at the unit place is 3 less than the number at the tens place.

So if the number at the units place is b, then the number at the tens place is 10(b+ 3)

So the number is thus;

10(b + 3) + b

= 10b + 30 + b = 11b + 30

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
