Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation 16-2*x-(5*x+9)=0
Pull out like factors : 7 - 7x = -7 • (x - 1)
Solve : -7 = 0 This equation has no solution.
A a non-zero constant never equals zero.
Solve : x-1 = 0 Add 1 to both sides of the equation :
x = 1

A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
The first step is:
- determine how far from the house is young equestrian at noon.
2 x 10 = 20 miles
15 t = 20 + 10 t
15 t - 10 t = 20
5 t = 20
t = 20 : 5
t = 4 hours
Answer: at 4:00 PM.
