Answer: n = 5
Step-by-step explanation: To solve for n, we must first isolate the term containing n which in this problem is 3n.
Since 8 is being added to 3n, we subtract 8 from both sides of the equation to isolate the 3n. On the left, the +8 and -8 cancel out and on the right 23 - 8 is 15.
So we have 3n = 15.
Now we can finish things off by just dividing both sides of the equation by 3. On the left the 3's cancel and on the right 15 divided by 3 is 5 so n = 5 and you can check your answer by plugging 5 back in for n in the original equation which is shown below in bold.
3(5) + 8 = 23 or 15 + 8 = 23.
Answer:
n = 5
Step-by-step explanation:
3n + 8 = 23
- 8 - 8 Subtract 8 from both sides
3n = 15
n = 5 Divide both sides by 3
the smallest number that is in the domain of
fog?
Answer:
The smallest number that is in the domain of fog is 3
Step-by-step explanation:
f(x) = (as corrected in comments)
g(x) = x-3
we need to find fog = f(g(x))
For finding f(g(x)) we put the value of g(x) inside the f(x)
f(g(x))=
The domain of this function is x ≥ 3
because if value of x is less than 3 than the result would be negative and we know √f(x) ≥ 0
So, the smallest number that is in the domain of fog is 3
Answer:
240 buns
Step-by-step explanation:
Hot dogs buns come in packages of 8.
Mr Spencer bought 30 packages of hot dog buns for the school picnic.
We have to multiply 30 packages with number of buns in one package.
He bought total number of hot dog buns = 30 × 8
= 240 buns
Mr. Spencer bought 240 hot dog buns.
