Im not sure but i think its 1.22474487
sorry just in case its wrong :(
Answer:
21
Step-by-step explanation:
so the relationship is that the music is ten times the commercials so, divide 210 by 30 and times that number by 3 210/30= 7, 7'3=21
The price increased so it would be a positive net change.
Subtract the new price from the original price:
45.83 - 30.46 = 15.37
The net change was C. $15.37
{ y=-8x
{ y=-4-10x
Substitution Method:
-8x=-4-10x
x=-2
y=-8(-2)
y=16
(x,y) = (-2,16)
Check solution
{ 16=-8(-2)
{ 16=-4-10(-2)
{ 16=16
{ 16=16
Elimination Method:
{ 8x+y=0
{ 10x-y=-4
{ 8x+y=0
{ -10x-y=4
-2x=4
x=-2
8(-2)+y=0
y=16
(x,y) = (-2,16)
*For checking, its the same with the substitution method
