The product of 57 and 10 is equal to 57 x 10 = 570.
57 x 857 = 48,84957 x 8.57 = 488.49
x = 1.333521432163324
answer this question can you help me what is the value of 5.7 x 10 with the 8 just above the 8
x+y = 10 and y = x+8 x+x+8 = 10 x+x = 10-8 2x = 2 x = 1 Substitute the value of x into the original equations to find the value of y: So: x = 1 and y = 9
x = -6
10 x 0.8 = 8
