45/X + 63/X= 108/X = Y, X= 108 divided by 2 = y, y=54
To find the density of the stone divide the mass by the volume:
Density of stone = 100 grams / 10 ml = 10g/ml
Since the density of the stone is more than the density of the water, it will sink.
Answer:
x = 4
Step-by-step explanation:
The equation comes out to be:
3x + 11 = 5x + 3
Move the <u>variables</u> to the left-hand side and change its sign
And move the <u>constant</u> to the right-hand side and change its sign:
3x - 5x = 3 - 11
Combine like terms to get:
-2x = -8
Isolate x by dividing -2 on both sides:
-2x/-2 = -8/-2
x = 4

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -12x + 5
f(-3) is x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-3) = -12(-3) + 5
- Multiply: f(-3) = 36 + 5
- Add: f(-3) = 41
