A division problem divides a 3-digit number by a 1 digit number. The quotient is 307 r3. What could the division problem be?
Tanya [424]

Answer:

There is no solution to this problem.

Step-by-step explanation:

The 1 digit number cannot be 1, since there would be no remainder.

The 1 digit number cannot be 2, since the remainder could be 0 or 1.

The 1 digit number cannot be 3, since the remainder could be 0, 1, or 2.

So, the 1 digit number must be greater than 3.  Let's start with 4.  Since the quotient is 307 (remainder 3), 4 x 307 is already more than 3 digits.

Solve for X. Type in your numerical answer only, do not type the degree symbol.
Alja [10]

Answer:

x = 4

Step-by-step explanation:

Due to the Consecutive Interior Angles rule, c + e = 180. So, 20x + 5 + 24x - 1 = 180.

If you solve, you will get x = 4

Work:

20x + 5 + 24x - 1 = 180 [Add like terms]

44x + 4 = 180 [Isolate the variable]

44x = 176 [Solve]

x = 4
