5g + 3 = 2g + 9 Subtract 3 from both sides
5g = 2g + 6 Subtract 2g from both sides
3g = 6 Divide both sides by 3
g = 2
Answer:
16pi cm^2, 112pi cm^3, 351.68 cm^3
Step-by-step explanation:
Given: Height=7cm, radius=4cm
1. The base is a circle and Area of circle = pi * r^2
Plug in the radius to get --> A = pi * (4cm)^2 = 16*pi cm^2
2. This is asking for the volume of the cylinder.
Volume of cylinder is V=h*pi*r^2 --> 7cm * pi * (4cm)^2 = 112 pi cm^3
3. Just plug 3.14 into pi --> 112 * pi cm^3 = 351.68 cm^3
I know it is a little messy but the answers are
For the first one = (0,7.5)
Second one = (0, 5 2/3)
Answer: x < 2
Step-by-step explanation:
The difference of x and 3 means subtract 3 from x is less than -1, we represent the question in the expression below:
X - 3 < -1
X < -1 + 3
X< 2
To solve, use properties of logs, specifically log(u)+log(v)=log(uv). This makes your equation logb(x+1)+logb(x-8)=logb((x+1)(x-8)), which can be made into logb(x^2-7x-8) by expanding the factored form.
