I think the answer is c it makes the most sense but I’m not sure
I think you either add all of the sides or multiply but i think you multiply
Answer:
I'm guessing 0.9
Step-by-step explanation:
For all of these we will use the Order of Operations, also known as PEMDAS, then compare the simplifed values to see if they are equal.
[a] Equivalent / Verified
(-5) * [(-7) + (-5)] = [(-5) * (-7)] + [(-5) * (-5)]
(-5) * [-12] = [35] + [25]
60 = 60
[b] Equivalent / Verified
(-7) * [(-8) + 9] = [-7 * (-8)] + [(-7) * 9]
(-7) * [1] = [56] + [-63]
-7 = -7
[c] Equivalent / Verified
(-25) * [(-7) + (-15)] = [(-25) * (-7)] + [(-25) * (-15)]
(-25) * [-22] = [175] + [375]
550 = 550
Answer:x = 0.028571 cm3
Step-by-step explanation:
I the density is constant and a mass of 3.5 g takes up 1 cubic centimeter, how much volume will a mass of 0.20 g take (in cubit centimeters)?
So, let x be the volume in cubit centimeters.
the mass is to the volume is as the mass is to the volume
3.5g /(1 cm3) = 0,1g / (x cm3)
Cross-multiply to get:
3.5x = 0.1
x = 0.1 / 3.5 (divide both sides by 3.5)
x = 0.028571 cm3 (you probably should round this, but diamonds are expensive !)
