Answer:
50 millimeters
Step-by-step explanation:
5=50
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the number of hours Eli worked
y ----> the number of hours Samantha worked
we know that
Eli and they ironed 400 shirts between them
so
-----> equation A
Samantha worked 2 more hours than Eli
so
----> equation B
solve the system by substitution
substitute equation B in equation A

solve for x

Find the value of y
substitute the value of x in equation B

therefore
The number of hours Eli worked was 6 and the number of hours Samantha worked was 8
Answer:
x=2π/3+π n
Step-by-step explanation:
Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.
Answer:
60 + 70n ≤ 200
Step-by-step explanation:
Since the $200 is a maximum, only inequalities with "≤ 200" make any sense in this context.
Since the unit rate for training sessins is $70, only expressions containing 70n make any sense in this context.
The only inequaity that makes any sense in this context is ...
60 + 70n ≤ 200
Using the given data you can build the linear regression (described by linear function y=ax+b) by hand or you can use math calculator to do this. In attached diagram you can see that

and

Then the equation of linear function is

Answer: correct choice is D.
