Answer:
The amount that Obi initially had was £20
Step-by-step explanation:
Let
x ----> amount that Obi initially has
y ----> amount that Rudy has
we know that

----> equation A


----> equation B
Solve the system by substitution
substitute equation A in equation B

solve for y

Find the value of x

therefore
The amount that Obi initially had was £20
11. 300=12x (X being the number of gallons per miles)
12. It will take 30 gallons of gas to travel 750 miles (first divide 300 by 12, which gives you 25 miles per gallon. Then divide 750 by 25, which gives you 30 gallons to travel 750 miles)
13. It'll cost a total of $112.5 for gas to go on your trip. (Multiply 30(gallons)×3.75(cost of 1 gallon)= 112.5(total cost of gas)
Answer:
4
Step-by-step explanation:
