geniusboy [140]3 years ago

When we have mixed signs we need to make it a negative. A plus and a minus or a minus and a plus are made into a minus by default.

With that in mind the question would not turn into 1 - 2 =

From here we take the sign of the bigger number. The bigger number would be negative 2 and we put it as the first part of our solution

This next step might be easier with a number line from -5 to 5

We start at positive 1 on the number line. From here we need to go left because when subtracting you go left. We move two spaces to the left. So the one goes to 0 and then it goes to -1

The answer would turn out to be <u>negative one</u><u>(</u><u>-1</u><u>)</u>

<u>1</u><u> </u><u>-</u><u> </u><u>2</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>1</u>

HOPE THIS HELPED!!! PLEASE DONT FORGET TO PUT THIS ANSWER AS THE BRAINLIEST. ALSO, LEAVE A HEART AND A 5 STAR TO LET PEOPLE KNOW IN THE FUTURE THAT THIS IS THE CORRECT ANSWER WITH A CORRECT EXPLANATION!! HAVE A GOOD DAY!

jolli1 [7]

Answer:

The bird dove 44 feet.

Step-by-step explanation:

If the bird starts 37 feet above the ocean and dives from its position to 7 feet below the ocean, the you just add the two numbers and get its total dive.

To draw it draw a graph that goes past to +37 and past -7, then draw a bar representing the birds dive from +37 to -7. The X axis would be time, and the Y axis is the bird's height relative to the surface of the water.
