Answer:
Amount each friend pays for the gift = $20
Step-by-step explanation:
Market price of a gift = $70
The store manager takes $10 off the market price.
Marked down amount = $10
New cost price = Marked price - Marked down amount 
The cost of the gift is divided among three friends.
This means that the cost of gift which is $60 is divided by three to get each one's contribution in the gift.
∴ Amount each friend pays for the gift 
X = 2
y = 1
You can get this by replacing the y in the second equation with the 3x - 5 from the first. Then solve for x. Once you have that value, you can solve for y.
Answer:
n > -2 or n < -3
Step-by-step explanation:
|2n+5| > 1
We have two solutions one positive and one negative. Remember to flip the inequality symbol for the negative
2n+5 > 1 or 2n+5 < -1
Subtract 5 from each side
2n+5-5 > 1-5 2n+5 -5 < -1 -5
2n >-4 2n < -6
Divide by 2
2n/2 > -4/2 2n/2 < -6/2
n > -2 or n < -3
Considering it's dimensions and the formula, the volume of the cuboid is of 160 cm³.
<h3>What is the volume of a rectangular prism?</h3>
The volume of a rectangular prism, such as a cuboid, is given by the <u>area of the base multiplied by the height</u>, that is:
V = Ab x h
In this problem, the base is a square of sides 4 cm, with the height of 10 cm, hence the volume is given by:
V = 4² x 10 = 160 cm³.
