Answer:

C.) 4

Step-by-step explanation:

Let's try all of the answer choices to see what we get.

-30 - 7 = -37

-37 × 3 = -111

Okay, so we can rule A out. Let's try the next one.

30 - 7 = 23

23 × 3 = 69

We can rule B out too. Let's move on.

4 - 7 = -3

-3 × 3 = -9

We worked it out and we got -9,, we're going to check the last one to be sure.

-4 - 7 = -11

-11 × 3 = -33

Now we are sure the answer is C.

79 x 31 rounding or compatible numbers . show how you estimate
Lubov Fominskaja [6]

Answer:

80 × 30 = 2,400

Step-by-step explanation:

We can easily round 79 up to 80 and round 31 down to 30. This would make our expression 80 × 30, which is much easier to compute. We just take 8 × 3 (which is 24) and add two zeros onto the end of the number. This yields us an answer of 2,400 which is very close to the actual multiplication of 79 × 31 which is 2,449 (only 49 more than our estimation).
