A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.Now the store has 62 Hip-Hop CDs,How many Hip-Hop CDs did

kow [346]

Answer: 130

Step-by-step explanation:

Let x be the original number of hip- hop CDs in the music store.

Given : A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.

i.e. The number of hip- hop CDs in the store will be :

Original No. of CDs - CDs sold + CDs Returned

$x-\dfrac{3}{5}x+10$

If the store has 62 Hip-Hop CDs now , then required euation will be :-

$x-\dfrac{3}{5}x+10=62$

Subtract 10 from both sides , we get

$x-\dfrac{3}{5}x=52$

$\Rightarrow\ \dfrac{5x-3x}{5}=52$

$\Rightarrow\ \dfrac{2x}{5}=52$

$\Rightarrow\ x=52\times\dfrac{5}{2}=130$

Hence, the number of CDs they originally have = 130

To prove that DEF congruent DGF by SAS,what additional information is needed

lisabon 2012 [21]

Answer:

∠DFE ≅ ∠DFG

Step-by-step explanation:

we know that

Triangles are congruent by SAS, if any pair of corresponding sides and their included angles are equal in both triangles

In this problem we have that

The pair of corresponding sides that are equal are

EF=GF and DF (is the same side for both triangles)

The included angle are ∠DFE and ∠DFG

therefore

The additional information needed to prove that triangles DEF and DGF are congruent by SAS is that angles ∠DFE and ∠DFG are equal

∠DFE ≅ ∠DFG
