(6,8) all you need to do is count in reverse to find the origin
In each case, divide the cost by the weight to find the cost per pound.
The unit rate is dollars per pound.
Sand a: $5/(60 lb) = 0.08333 $/lb
Sand b: $12/(150 lb) = 0.08 $/lb
A. Sand a is 0.08333 $/lb
B. Sand b is $0.08 $/lb
Sand b has a lower unit rate.
Sand b is is the better value.
If you buy the same amount of sand a and sand b, you will spend less money per pound of sand by buying sand b.
Answer:
true ...
believe it or not there is an exponential sequence that can make that
result
f(x) = 
<u>x /// 2(x+2) -1</u>
-1 /// 1
0 /// 3
1 /// 5
2 /// 7
Step-by-step explanation:
Answer:i think you have to equal them to each other
Step-by-step explanation:
36 minutes.
(1/20)x+(1/30)x=1solve for x (x=0.8333333333......)
Considering they take the same times for all 3 pounds,
That would mean that since 1 pound takes 12 minutes, then 3 pounds take 36 minutes
