Answer:
(3,0.5)
Step-by-step explanation:
The given system has equations:

Let us multiply the second equation by 4 and the first equation by 10.

We add both new equations to get:

Put x=3 into the first equation and solve for y.

The point of intersection is the solution to the system of equation which is (3,0.5)
Answer:15
Step-by-step explanation:
You have to divide the fractions so it 3/4÷1/10 then you can do keep change flip so the new equation is 3/4×10/1 or 3/4×10 then cross simply then get 3/2×5/1 to get 15/2 then use division to get 7 1/2
Answer:
288
Explanation:
As first term in sequence is 3 so multiplying it by common ratio 5 we get 15, then multiplying 15 by 5 we get 45 and so on the sequence is
