Answer:
Step-by-step explanation
this is the equation r+j=6
this is too r+9=j
from the equation you can tell that r=j-9 if u re=arrange it
now you put r=j-9 into one of the equation up there ↑
j-9+j=6
2j=15
j=7.5
I believe it would be 100 * 3 + 300 = 600. But there isn't too much information to understand what you're asking.
Hope I helped anyways! :)
The last option would be the correct answer
Answer:
not sure
Step-by-step explanation:
Find the Greatest Common Factor (GCF):
GCF = 6
Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF):
6(42/6 + 24n/6)
Simplify each term in parentheses:
6(7 + 4n)
DONE !!
