The units digit of a two-digit number is four more than the tens digit. If the number is doubled, it will be 1 more than the reversed number. Find the number.

The number is 37

Step-by-step explanation:

The given parameters are;

The unit digit of a two-digit number = 4 + The tens digit

2 × The two-digit number  = 1  + The reversed number

Let x represent the unit digit and y represent the tens digit, we have;

x = 4 + y

2 × yx = xy + 1

Which gives;

2 × yy+4 = 2y2y+8

xy + 1 = 4 + yy + 1

y + 1 = 2y + 8 - 10 (we assume that the product of 2 and the unit digit is more than 10 so we subtract 10 from the product to equate the unit digits of the two numbers

10 + 1 - 8 = 2y - y

10 - 7 = y

y = 3

x = y + 4 = 3 + 4 = 7

x = 7

Therefore, the number = 37.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

i think its a and d
