Answer: n = -rt/10 + 1/10
Explanation: isolate the variable by dividing each side with the factors that don’t contain n, then isolate n to get this answer.
Hope this helps!
Answer:
.
Step-by-step explanation:
Not sure what algebra tiles are
not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x
remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x
To find the amount of "tens" in a number, divide it by 10
8,000÷10=100
Answer: There are 800 tens
