Answer:

x = -4

Step-by-step explanation:

- 3x = 12

Lets divide both the sides by -3.

=  >  \frac{ - 3x}{ - 3}  =  \frac{12}{ - 3}

=  > x =  - 4

When Sarah divided a number by 5, the quotient was 247 with a remainder. What is one possible dividend? With a complete sentence
Stolb23 [73]

Answer:

When a number is divided by 5 and the result is 247 with a remainder, one possible dividend is 1236.

The quotient of  a number is the number that is gotten when a number is divided by another number. For example, the quotient of 10 and 2 is 5.

An unknown number was divided by 5 and the result was 247 with a remainder. In order to determine the number the first step is to determine the product of 247 and 5.

247 x 5 = 1235

Since the number has a remainder, the number cannot be exactly 1235. The number would lie between 1235 and 1240. The numbers can be 1236, 1237, 1238 and 1239.
