Answer:
Step-by-step explanation:
Solve for n:
⇒2m - n = 8
Subtract 2 m from both sides:
⇒2m - 2m - n = 8 - 2m
2m - 2m = 0:
⇒-n = 8 - 2 m
Multiply both sides by -1:
⇒-n × (-1) = (8 - 2m) × (-1)
⇒n = 2m - 8
Step-by-step explanation:
If we take 4 as k then
4k = 4(4) = 16 boxes
k + 9 = 4 + 9 = 13 boxes
Multiply both sides by 7 and then you get 4s-7=21. then add 7 to 21. then you have 4s=28. then divide both sides by 4 and you get s=7
Answer:
3 ways
Step-by-step explanation:
Since 6 will remain constant throughout the testing, we just need to find all prime numbers 1-6.
1 - is not prime nor composite
2 - is prime
3 - is prime
4 - 2x2=4, so composite
5 - is prime
6 - 2x3=6, so composite
Therefore, 2, 3, and 5 are prime numbers, and there are 3 of them.
Answer:
The correct answer is A) (f+g)(x) = 15x - 2
Step-by-step explanation:
In order to complete a composite addition function, you need to add the two functions together combining like terms.
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 3x - 10 + 12x + 8
(f+g)(x) = 15x - 2
