Answer:
6 apples and 5 bananas
Step-by-step explanation:
x + y = 11
x = 11 - y
1.75x + 0.70y = 14
1.75(11 - y) + 0.7y = 14
19.25 - 1.75y + 0.7y = 14
5.25 = 1.05y
y = 5
x = 11 - 5 = 6
Answer:
Assuming you mean until the lunch money balance runs out,
$2.20x = $23
Step-by-step explanation:
You spend $2.20 every day. If you are trying to find how many days until the lunch balance runs out, you need to put in X as your variable.
The last step is to set it equal to $23 dollars to be able to factor out the answer.
Hope this Helped!
Answer: Anita's
Step-by-step explanation:
Anita's shape would have the longest sides because she only has 4 total sides, while the others have 5, 6, and 10
This means that if the total perimeter for each of the shapes was 10 units,
Anita's shape would have side lengths of about 2.5 units while the others would have side lengths of 2, 1.6, and 1 units.
This means Anita's shape has the longest sides
Answer:
(3x - y)(3x + y)
Step-by-step explanation:
Both 9x^2 and y^2 are perfects squares.
The rule for factoring perfect squares is a^2 - b^2 = (a - b)(a + b).
Here, factoring (3x)^2 - y^2 results in (3x - y)(3x + y).
