Explain why 0.25 ×0.4 has only one decimal place in the product

Negative 5 1/12 + negative 4 1/4 + 6 3/4

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Indicate the formula for the following conditions: p^c(n,r)=
