Solve the system of equations by the addition method. If the system does not have a single ordered pair as a solution, state wh
ether the system is inconsistent or dependent. 15x-18=3y 5x=y+6
1 answer:
Answer:
dependent
Step-by-step explanation:
The given system is :
15x-18=3y
5x=y+6
Rewrite the equations in standard form to get:
15x-3y=18
5x-y=6
Multiply the bottom equation by 3.
15x-3y=18
15x-3y=18
Sub both equations:
0-0=0
0=0
We got an identity
The system is dependent because there are infinitely many solutions

Answer:
the answer is 63.96
because 20% of 79.95 is 15.99
Complementary angle= two angle whose sum is 90°
a= x +27
b= x
2x+27=90°
2x= 90-27
2x=63
x=63/2
x= 31.5 or 31°30'
b= 31°30'
a= 31.5+27= 58.5---->58°30'
You just need to plug 12 in for x in the equation.
f(12)=4(12)+5
f(12)=53
The answer is B
89+12+9=110
100(.25)=27.5
110-27.5=82.5
