⁷/₁₀ kg

Given:

Question:

How many kilograms of cherries did they buy altogether?

The Process:

The least common multiple (LCM) of 5 and 10 is 10.

Therefore, Linda bought of cherries.

Let us find out how many kilograms of cherries did they buy altogether.

Thus, they bought of cherries altogether.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
