Assuming the inteest is annual, since it's simple that means we just have to analyze:
, where r is our interest rate as a decimal, t is time, p is our principal investment and A is our ending value. So, in the context of our problem this becomes:
, which when evaluated by our trusty calculator becomes:
7657.68938,
which is rounded to 7500 in the problem.
Answer:
(16a+20a)-18b
=36a-18b
Step-by-step explanation:
Answer:
42
Step-by-step explanation:
180-42=138
180-138=42
Explanation:
1. Identify the different constellations of variables. Here there are three:
2. Combine coefficients of each of the different variable constellations:
(8.1 -2.8)b +(6.7 +0.9)a +(2.5 +7)
5.3b +7.8a +9.5
3. Perform any other operations that might be required depending on the sort of equivalent wanted. For example, one could write ...
5.3(b +(78/53)a) +9.5 . . . . . . . shows the weight of a relative to b
Haha yeah hard question lol its "0"
;))
