Answer:
B
Step-by-step explanation:
3x=15
Divide both sides by 3 to isolate the x variable.
x=15/3=5
The answer is B. If you substitute the values of x, y and z in you get 1 * -10 which just is -10. -10 / 2 = -5.
7+x, because the sum means adding.
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
