To the nearest hundredth, which is the value of x in the solution of the following system? 3.5x - 2.8 = -4.67x + 12.5 Select one: a. -3.75 b. -1.87 c. 1.87 d. 3.75

C. 1.87

Step-by-step explanation:

3.5x - 2.8 = -4.67x + 12.5

3.5x + 4.67x = 12.5 + 2.5

8.17x = 15.3

x = 15.3 ÷ 8.17

x = 1.87270501836

So, the closest choice to 1.87270501836 is 1.87, so the answer is C.

Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
