Answer:

10=40

50=30

Step-by-step explanation:

Suppose the number of 10 paise coins =x

∴ the number of 50 paise coins =70−x

Now, value of 10 paise coins = Rs.  

10 x  and value of 50 paise coins = Rs.   2 70−x

Total value of coins =   10 x +  2 70−x

​∴  10 x  +  2 70−x  =19

Multiplying both sides by 10, (LCM of 10,2=10), we get  

x+5(70−x)=19×10    

x+350−5x=190

−4x=−160

−4 −4x  =  −4 −160

​∴x=40

∴ number of 10 paise coins =40  

Number of 50 paise coins =70−40=30.

Solve the equation for x.
liq [111]

Answer:

x=55

Step-by-step explanation:

The given equation is \sqrt{x-6}+3=10

Group similar terms to get:

\sqrt{x-6}=10-3

\sqrt{x-6}=7

Square both sides to obtain:

x-6=7^2

x-6=49

Add 6 to both sides

x=49+6

Simplify the right hand side to obtain;

x=55

A couple is required by their lender to have a down payment of 20% of the purchase price of the home they want to buy. If the co
Stella [2.4K]

Down payment is 20% of the price of the home. Since the couple saved $35,000, and assuming they will pay the whole money as down payment, the highest priced home they can get is a price whose 20% is $35,000.

We can setup an equation in x (being the price of home) to get the price of the most expensive home they can buy.

<em>Which number (x) , multiplied by 20%, is equal to $35,000?</em>

<em>x(0.2)=35,000\\x=\frac{35,000}{0.2} \\x=175,000</em>

So, the most expensive house they can buy is worth $175,000.
