Answer:
There are infinitely many solutions to the system because the equations represent the same line
Answer:
The perimeter is 22.
Step-by-step explanation:
The perimeter formula (it sometimes varies) is 2(b+h)
b being base (in this example, 6)
h being height (in this example, 5)
So now, with substitution, we are left with:
2(6+5)
Which simplifies down to:
2(11)
22
Answer:
$9
Explanation:
First, we need to find 70% of the original price of $30 using the following equation:

It means that Emma pays $21 less than the original price. So, she pays:
$30 - $21 = $9
Therefore, the answer is $9
220 (divide sign) 5 = 44ml (change it to liters) 0.044 (move the decimal from 44.0 their by two spots so it would be 0.044)
