Complete question:

Which equation accurately represents this statement? Check all that apply.

Negative 3 less than 4.9 times a number, x, is the same as 12.8

A: - 3-4.9x=12.8

B: 4.9x - (-3) = 12.8

C: 3+4.9x=12.8

D: (4.9-3) x=12.8

E: 12.8=4.9x+3

Answer:

B: 4.9x - (-3) = 12.8

C: 3+4.9x=12.8

E: 12.8=4.9x+3

Step-by-step explanation:

The word equation can be expressed mathematically as follows

negative 3 → - 3

less than 4.9 times a number, x → 4.9 x - (-3)

is same as 12.8 → 4.9 x - (-3) = 12.8

The equation can be expressed as

4.9 x - (-3) = 12.8

when you open the bracket, you multiply - 3 time - 1. MInus times minus is equals to plus. so you get

4.9 x + 3 = 12.8

12.8 = 4.9x+3

X = 2

Step-by-step explanation:

4.9x - (-3) = 12.8

4.9x = 12.8 + (-3)

4.8x - 12.8 = - 3

Can be three different forms

To solve:

4.9x = 12.8 - 3

4.9x = 9.8

x = 2
