Answer
he assaighed 6 problems to each of them
Step-by-step explanation:
he assaighned 2 to each if the total is 30 that means 30 / 5 = 6 so x = 4 and the student had 6 problems
Answer:
A- y=0.5x+3
Step-by-step explanation:
The Rule of 72 is a basic method to decide how stretched an investment
will take to double. It is specified with a fixed annual rate of interest. The
annual rate of return would be divided by 72, stockholders can now get an
approximate guess of how many years it will take for the original investment to
duplicate itself.
So basically, the formula is 72/r where r is the annual
rate. So the solution for this is to divide 72 by 18, to get the answer. The answer
is 4 years.
Answer:
13y+15
Explanation:
4y-2.5+ 4y-2.5+ 2.5y+10+ 2.5y+10=13y+15
Using Pythagorean theorem.
16^2 + (RT)^2 = 20^2
256 + (RT)^2 = 400
(RT)^2 = 144
RT = 12
Using altitude theorem to find ST:
16/12= 12/ST
16ST = 144
ST = 9
Using Pythagorean theorem again:
12^2 + 9^2 = SR^2
144 + 81 = SR^2
225 = SR^2
SR= 15
Final answer: SR= 15
Hope this helps!
