Answer 2

According to Google Translate, the text you entered is in Ukrainian and it means:

Answer in detail. They brought 126 tons of cement to the construction site, and 4 times more sand. They spent a tons of sand per day. How many tons of sand are left?

To solve this problem, we need to find out how much sand was brought to the construction site and how much sand was used in one day. Then we can subtract the used amount from the total amount to get the remaining amount.

Let x be the amount of sand brought to the construction site. Since it is 4 times more than the cement, we can write:

x = 4 * 126

x = 504

So, 504 tons of sand were brought to the construction site.

Let a be the amount of sand used in one day. We know that they spent a tons of sand per day, so we can write:

a = a

So, a tons of sand were used in one day.

To find out how many tons of sand are left, we need to subtract the used amount from the total amount. We can write:

Remaining sand = Total sand - Used sand

Remaining sand = x - a

Remaining sand = 504 - a

So, 504 - a tons of sand are left.
