1/2 a number is equal to the sum of three-fourths of the number and -2.find the number.

1/2 a number = x/2

the sum of three-fourths of the number and -2: 3/4 + -2 = -5/4

We know that they're equal, so:

x/2 = -5/4

Multiply both sides by 2 to isolate the x and find the number:

x = -5/2

Therefore, the number is -5/2.

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
