Density = mass / volume
So if we know the density and volume, make an algebraic equation of this.
4.1 = m ÷ 2.3
Multiply each side by 2.3.
9.43 = m
The mass is 9.43 grams, hope this helps!
Answer:
No
Step-by-step explanation:
To convert a decimal to a fraction you multiply by one hundred. Then, you write that number as a fraction over 100 and simplify. Eg 0.5×200 = 50 , 50/100 simplifies to 1/2. Therefore 0.05 as a fraction is 0.05×100 = 5, 5/100 simplified = 1/20
Answer:
Yes
Step-by-step explanation:
Plug in (-1 , -2) in the LHS of the equation.
2x - 3y = 2*(-1) - 3*(-2)
= -2 + 6
= 4 = RHS
So, (-1 , -2) is a solution
