Think about the individual parts of the expression.
5b - a
5b equals 625. Therefore, 5b - a = 625 - a
Now you have 625 - a.
If 5a = 25, then what does "a" equal? Divide 5 from both sides to find out.
5a/5 = 25/5
a = 5
Therefore, 625 - a = 625 - 5
625 - 5 = 620
620 is the answer.
250000 I think? I don't really know what a hectare is so..
Answer:
so it's
3/7m<21
and we devide both sides of the inequality.
/2r-1\>7
And we can rewrite it as a compound Inequality
2r-1<7 (or) 2r-1>7 Ima give u the enter
[r<-3 or r>4 I guess it's like this❕

Answer:
Step-by-step explanation:
The first differences are 8, 13, 21. The second differences are 5, 8. The second differences are not constant, so this is <em>not a quadratic sequence</em>.
If we assume it is a cubic sequence, a calculator tells us the formula is ...
