Which graph? I can not see any graph in there
Answer:
107°
Step-by-step explanation:
m∠m+m∠p= 180°
(7x+31)°(21x-19)°=180°
7x+31+21x-19= 180
7x+21x=180+19-31
28x=168
x= 168/28
x= 6
m∠p= (21x-19)°
= (21(16)-19)°=(126-19)°
= 107°

hope it helps..
have a great day!!
Eg. the first loan is x, the second loan will be (9,000 - x)
First, we need to make an equation based on the problem
first interest + second interest = 492
5% of x + 6% of (9,000 - x) = 492
<em>This is the equation</em>
Second, solve the equation and find out the value of x (first loan)
0.05x + 0.06(9.000 - x) = 492
0.05x + 540 - 0.06x = 492
-0.01x + 540 = 492
-0.01x = 492 - 540
-0.01x = -48
x = -48/-0.01
x = 4,800
Third, find the second loan
9,000 - x
= 9,000 - 4,800
= 4,200
SUMMARY
The first loan that has interest of 5% is $4,800
The second loan that has interest of 6% is $4,200
