Step-by-step explanation:
7m+11= -4 x 2m + (-4 x 3)
7m +11 = -8m -12
7m +8m = -12-11
15m = -23
1 inch = 0.0277778
1 * 46 = 46
0.0277778 x 46 = 1.27778
46 inches = 1.27778
I think is 3 and 2/3 (I hope I got it right)
Answer:
I got 5.65
Step-by-step explanation:
36/8= 4.5, 4.5 +1.25= 5.65
1.28 = 128 * 10^-2
128 * (1/10^2)
128 / 10^2
128 / 100
1.28
