Each time Sally waters her tomato plants she uses 5 liters of water. If Sally waters her tomato plants 3 times a week, then how much water, in liters, does Sally use in a week? liters

Given:

Each time Sally waters her tomato plants she uses 5 liters of water.

Sally waters her tomato plants 3 times a week.

To find:

How much water, in liters, does Sally use in a week?

Solution:

We have,

Water used in each time = 5 liters

Number of times Sally waters her tomato plants = 3 times

Now,

Water used in 1 time = 5 liters

Water used in 3 time = 3×5 liters

                                   = 15 liters

Therefore, the Sally use 15 liters of water in a week.

x=2,y=−1

Step-by-step explanation:

Solve for y in the first equation.

y=−9x/11+7/11

0=−2y+10−6x

Replace all occurrences of y with −9x/11+7/11 in each equation.

0=−48(x−2)11

y=−9x11+711

Solve for x in the first equation.

x=2

y=−9x/11+7/11

Replace all occurrences of x with 2 in each equation.

y=−1

x=2

The solution to the system is the complete set of ordered pairs that are valid solutions.
