Leona [12618]
d Step-by-step explanation: when f(x)=5......It can also be expressed as f(x)=1/125(625x). This is applicable to any whole number over one, with 1(625x)=625x. Therefore, since 125(1)=125, we find (625/125)x=5x.

A​ 0.8-liter bottle of Mexican wine costs 101 pesos. At that​price, how much would a​ half-gallon jug of the same wine cost in​d
AnnZ [12381]

Answer:

$12.18

Step-by-step explanation:

Provided:

The price of a 0.8 liter bottle of Mexican wine amounts to 101 pesos.

Consequently,

The price for 1 liter of Mexican wine can be determined as \frac{\textup{101}}{\textup{0.8}} pesos.

Additionally,

Converting, 1 Mexican peso equates to 0.051 dollars.

As a result, the equivalent cost of 1 liter of Mexican wine is \frac{\textup{101}}{\textup{0.8}}\times0.051 dollars.

Moreover,

Knowing that 1 gallon equals 3.78541 liters;

Thus, half a gallon equals \frac{\textup{3.78541}}{\textup{2}} = 1.892705 liters.

Therefore, the cost for a half-gallon jug would be \frac{\textup{101}}{\textup{0.8}}\times0.051\times1.892705 dollars.

In conclusion, the price for a half-gallon of this wine is $12.18.

Mr Wong spent a total of $176 on a jacket a belt and a wallet. The wallet cost $31 more than a belt. The jacket cost 3 times as
PIT_PIT [12445]
Wallet = belt + 31
jacket = 3 · belt

176 = belt + wallet + jacket

176 = belt + (belt + 31) + (3 · belt)
176 = (2 · belt) + 31 + (3 · belt)
176 = (5 · belt) + 31
5 ·belt = 145
belt = 29
