Purchasing a TV that is 20% off will save $180.

Flauer [41]

Answer:

$900

Step-by-step explanation:

a)Off given on purchasing a TV= 20%

20% on TV = $ 180

Let the original price of TV set $ x

According to question,

20% of x= $180

$\frac{20}{100}$ ×x= $180

x = $ 180× 5

x= $ 900

Hence, Original price of TV set= $ 900

b) By second method,

20%= $180

1%= $ 9

100% = $900

Hence, the original price $ 900

Which equation can be used to find the solution of (1/4)^y+1=64?

Ne4ueva [31]

Answer:

−y−1=3

Step-by-step explanation:

Which equation can be used to find the solution of (1/4)^y+1=64?

This can be solved by power of indices

(1/4)^(y+1)=64

(4^-1)^(y + 1)= 4^3

Note

(x^a)^b = x^ab

Hence:

4^(-1)(y + 1)= 4^3

4^-y - 1 = 4^3

Divide both sides by 4

−y−1=3

Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is

−y−1=3
