Answer:
x ≈ 6.5
Step-by-step explanation:
We have the epresion 
and we want to find the value of 
.
Let's do it step-by-step
Step 1. Multiply both sides of the equation by 20
Step 2. use the reflexive property of equality: if 
then 
Step 3. Using a calculator we get that 
. Replacing that value we get
x ≈ 6.5
We can conclude that the value of x is approximately 6.5
Answer:
the answer is 3x minus 2 because when u combine the x terms it's 3x and 2 doesn't have any other like term
Answer:
1 + (2 + (-3)) = 0 = (1 + 2) + (−3)
1 × (2 × (−3)) =−6 = (1 × 2) × (−3)
Answer:
89.80 cm cubed
Step-by-step explanation:
A hemisphere is essentially just half of a sphere. We want to find its volume.
The volume of a sphere is denoted by: V = (4/3)π * r³, where r is the radius. That means the volume of a hemisphere, which is half a sphere, will be denoted by: V = (1/2) * (4/3)π * r³ = (2/3)π * r³.
Here, the radius is 3.5, so plug this in:
V = (2/3)π * r³
V = (2/3)π * (3.5)³ ≈ 89.80 cm cubed
try 5.5 or 5 1/2 I hope this helps!
