Answer:
Expression : 300,000 + 7x% = a
a = 384,000
Step-by-step explanation:
a = population in 4 years
x = every year increased
Expression: 300,000 + 7x% = a
300,000 + 7x% = a
replace x what will its population be in x years variable (this is 4)
300,000 + 7(4)% = a
multiply 7(4)
300,000 + 28% = a
Add 28% of 300,000 to 300,000
384,000 = a
Answer:
example of Analog computer=
Operational amplifiers
3a + 2ab - 6 + 2b - ab
First, gather like terms. / Your problem should look like: (3a - 6a) + (2ab - ab) + 2b
Second, simplify. / Your problem should look like: -3a + ab + 2b
Answer: -3a + ab + 2b
