Answer:
The correct answer is d, there are infinitely many solutions.
Step-by-step explanation:
If the variable terms are the same and the constants are the same, the equation has infinitely many solutions.
Ex: 5(3)+5(5)=40 3+5=8
5(4)+5(4)=40 4+4=8

Answer:
a = 6 and b = 36
Step-by-step explanation:
Set up equations:
b = 30 + a
b = 6a
Subtract the two equations:
b = 6a
- (b = 30 + a)
5a - 30 = 0
5a = 30
divide both sides by 5
a = 6
Plug a = 6 into the original equation:
b = 30 + 6
b = 36
you could also do:
b = 6 * 6
b = 36

1) we have to calculate the increase of the cost of the jacket.
Increase of the cost of the jacket=new price - previous price
increase of the cost of the jacket=$87.75 - $75.00=$12.75
2)Now, we calculate the percentaje incresae of the costo of the jacket by the rule of three.
$75=100%
$75------------------100%
$12.75------------- x
x=($12.75 * 100%) / $75=17%
Answer: the percentage increase of the cost of the jacket is 17%
