Answer:
idk im doing to same thing in class im confused too
Step-by-step explanation:
For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:
The maximum number of pillowcases she could have purchased is:
x = 8 (spent less than $ 40)
Answer:
45 °
Step-by-step explanation:
m< ABC = m< DBC + m< ABD
= 115 _ 70
= 45 °
Yes it is because 4+4=8 and 8 is larger than 7
$20 because 10% of 40 is 10 and the price now is 40 so 2 years before would have been 20
