Could someone help with this math question please brainlest and points

-3

Step-by-step explanation:

YOu first have to simply the equation first. -2x+5<7. You first subtract each side by 5, which gives -2x<2. Dividing both sides by -2 gives x>-1 (Remember you have to flip the signs ; D) So x has to be bigger than -1. -3 is the only number that is smaller than -1.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
