Answer:

Yes

Step-by-step explanation:

All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares. The opposite interior angles of rhombuses are congruent. Diagonals of a rhombus always bisect each other at right angles.

kkurt [141]

Answer:

y > -14

Step-by-step explanation:

-5(y+2) < 60

-5y - 10 < 60 (Expand the term on the left)

-5y < 70 (Bring the numbers to the right)

y > -14 (Divide both sides by -5. Note that the inequality sign changes as we are dividing by a negative number)

Morgarella [4.7K]

Answer:

6 notebooks for 5.25 is a BETTER BUY.

Step-by-step explanation:

Here, according to the question:

A) 8 notebooks sells for 7.15

$\textrm{Cost of 1 notebook} = \frac{\textrm{Cost of n notebooks}}{\textrm{n}}$

So, here cost of 1 notebook = $(\frac{7.15}{8} ) = 0.893$

⇒Here the cost of 1 notebook = $0.893

B) 6 notebooks sells for 5.25

$\textrm{Cost of 1 notebook} = \frac{\textrm{Cost of n notebooks}}{\textrm{n}}$

So, here cost of 1 notebook = $(\frac{5.25}{6} ) = 0.875$

⇒Here the cost of 1 notebook = $0.875

Now, as we can see $0.893 > $0.875

⇒ the cost of 1 notebook is MORE if we buy 8 notebooks sells for 7.15.

Hence, 6 notebooks for 5.25 is a BETTER BUY.
