Answer: Hi Hope This Helps :D
Step-by-step explanation:
We have to calculate the annual interest rate for the account. Formula for the simple interest is : I = P * r * t, where P is the investment, r is the annual interest rate and t is time in years. In this case: 1,800 = 10,000 * r * 4; 1,800 = 40,000 * r; r = 1,800 : 40,000; r = 0.045, or 4.5 %. Answer: The annual interest rate is 4.5 %
 
        
             
        
        
        

Given inequality
=> −2(x+1)≥3x+8
=> 

now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides 
=> x >_ -2
HOPE IT HELPED YOU.

X+y=156
<span>0.05x+0.25y=21.6
-1/4*/ x+y=156
1/20x+1/4y=216/10
-1/4x-1/4y=156*-1/4=-39
</span>1/20x+1/4y=216/10
<span>+--------------------------
-4/20x=-17,4
x=87
</span>x+y=156
