Answer:
9.) B. division
10.) 8
Explanation:
9. Which operation to do first in order of operations?
Answer: Applying BODMAS where:
[B] brackets
[O] order
[D] division
[M] multiplication
[A] addition
[S] subtraction
Maintaining order, division operation is done first. Then multiplication and then addition and so on.
10. Given that N = 48 ÷ 3 × 2
⇒ N = 48 ÷ 3 × 2
⇒ N = 48 ÷ 6
⇒ N = 8
2(x - 5) = 110
2x - 10 = 110
Add 10 to both sides.
2x = 120
Divide by 2 on both sides.
x = 60
Answer:
10 in
Step-by-step explanation:
So we want to consider the surface area of this sphere.
The formula for surface area of a sphere is 
.
So we have that the surface area is 
.
So I'm going to replace 
in with .
Now our main objective here is to solve for 
:
Divide both sides by 
:
This gets us 
by itself:
What number squared gives you 25? If you don't know, just take the square root of both sides giving you:
Now you can just put 
in your calculator. You should get 5.
5 is the radius
The diameter is twice the radius.
So 2(5) is 10, so the diameter is 10 in.

Answer:
x² - x - 6
Step-by-step explanation:
Step 1: Write expression
(5x² + 2x - 5) - (3x² + 3x + 1)
Step 2: Distribute negative
5x² + 2x - 5 - 3x² - 3x - 1
Step 3: Combine like terms (x²)
2x² + 2x - 5 - 3x - 1
Step 4: Combine like terms (x)
x² - x - 5 - 1
Step 5: Combine like terms (constants)
x² - x - 6
