Step-by-step explanation:
105min=1 hour and 45 min
If it is 2.25 yards per dress, and 4.15 a yard, multiply 2.25 by 4.15 and you get 9.3375 or just 9.34. if there are 4 girls, multiply 9.34 by 4 and you get $39.76
For this equation I would assume you use substitution, you plug in what y equals (3x -2), for the y in the second equation (4x - 4y = 8), you now have 4x - 4(3x-2) = -8 you then proceed to factor out this equation, you distribute the -4 and now you have 4x -12x + 8 = -8 you then subtract the -12x from the 4x and the result is -8x + 8 = -8, you then proceed to isolate the x subtracting the 8 from both sides and you now have -8x =-16 you then isolate the x by dividing -8 from both sides, your results are x = 2, you answer isn’t negative 2 because when you divide two negatives they cancel out creating a positive number.
3.70207 x 102 is 370.207 in scientific notation :)
