Answer:
The system of equations 10d+25q=375 and q = 3d-2 can be used to find the numbers of dimes and quarters that Joann has.
Step-by-step explanation:
Given that:
Total value of dimes and quarters = $3.75 = 3.75*100 = 375 cents
One quarter = 25 cents
One dime = 10 cents
Let,
d be the number of dimes
q be the number of quarters
According to given statement,
10d+25q=375
q = 3d-2
Hence,
The system of equations 10d+25q=375 and q = 3d-2 can be used to find the numbers of dimes and quarters that Joann has.
Answer:
given mass =1500kg
intial velocity(u)=0 m/s
final velocity(v)=20m/s
time(s)=10 sec
accelerating force of the car engine=final velocity-intial velocity/time=20-0/10=20/10=2m/s^2
