Answer: the final mass of the solid is 176 grams.
Step-by-step explanation:
The "change" between two quantities, one initial Qi and one final Qf is defined as:
Change = Qf - Qi.
In this case, the quantity is mass, and we know that the initial mass is 260 grams.
And we also know that the change is -84 grams.
Then we have the equation:
Qf - 260 g = -84g
Qf = -84g + 260g = 176g
So the final mass of the solid is 176 grams.
Answer:
2x - 5
Step-by-step explanation:
1/5(10x - 25)
Use the Distrubitve Property
1/5 * 10x = 2x
1/5 * 25 = 5
New equation is 2x - 5
Answer:
-7 < y < 2 (Line under <) is the answer
Answer:
A number decreased by 8 is less than 23.
X^2 - x - 42 = x^2 - 6x + 7x - 42 = x( x - 6) + 7(x - 6) = (x-6)(x+7);
The correct answer is a.
