Answer:
it's density is 8 g /cm³
Step-by-step explanation:
Mass (m) = 96 g
Volume (v) = 12 cm³
Density (d) =?
We know density is defined as mass per unit volume so
d = m/v
= 96 / 12
= 8 g/cm³
Hope it will help :)
Note : if in the question it is said to write in sI system u have to write in kg/m³.
Here's how you solve this. So, x+y=2, right? Let's isolate x. x+y-y=2-y. x=2-y. NOW, if x=2-y, in 3x+2y=5, we can REPLACE x with 2-y and use it to solve for y! 3x+2y=5. 3(2-y)+2y=5. (3*2)+(3*-y)+2y=5. 6+(-3y)+2y=5. 6+(-y)=5. 6+(-y)-6=5-6. -y=-1. -y/-1=-1/-1. y=1.
So, if y=1, we can substitute that back into either equation--but let's go with the easier one, x+y=2. x+1=2. x+1-1=2-1. x=1. 1+1=2, so that works; let's check the other equation. 3(1)+2(1)=5. 3+2=5. 5=5. That's correct!
Answer: x=1, y=1
Answer: Hi!
Sara had 2/3 of a piece of cake. Jasmine had 2/5 of a piece of cake. How much cake did Sarah and Jasmine have in total?
Hope this helps!
To complete the table, plug in the values into the equation (y=2x+3) if you already have the y then solve for x using inverse operations, and if you have the x then just use order of operations like normal
