Mia tried to multiply 90\times5090×5090, times, 50 by decomposing 909090 and 505050 into multiples of 101010. Her work is below: \begin{aligned} \phantom{=}&~90 \times50 =&~ (9\times 10) + (5\times10) &\greenD{\text{Step } 1} =&~ (9 \times 5) + (10\times10) &\goldD{\text{Step } 2} =&~45 + 100&\blueD{\text{Step } 3} =&~145&\purpleC{\text{Step } 4} \end{aligned}

What is the simplified form of (3.25x10^3)(7.8x10^6) written in scientific notation?

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)
