Given:
6 . ln x = 9.1
We are asked to find the solution of the above equation leaving the answer to two decimal places.
6lnx = 9.1
Let's divide both sides by 6
6linx/6 = 9.1/6
6 cancelling out on the left hand side.
lnx = 9.1/6
linx = 1.5166
x = e^1.5166
x = 4.5570
x = 4.56 (to two decimal places).
The correct option is A, which is x = 4.56
Answer:
Step-by-step explanation:
combine 2x and 4x to get 6x. Add 5 to 37 to get 42. divide the 6 and 42 to get x=7
M = miles Marcos drove
c = miles Candice drove
m = 2c
m + c = 66
Plug m=2c into the second equation :
m + c = 66
(2c) + c = 66
3c = 66
Choice A
3/4 = 6/8 = 9/12 = 12/16 = 15/20 = 18/24 = 21/28 = 24/32 = 27/36 = 30/40 = 33/44 = 36/48 = 39/52 = 42/56 = 45/60 = 48/64 = 51/68 = 54/72 = 57/76 = 60/80 = 63/84 = 66/88 = 69/92 = 72/96 = 75/100 = 78/104 = 81/108 = 84/112 = 87/116 = 90/120 = 93/124 = 96/128 = 99/132 = 102/136 = 105/140 = 108/144 = 111/148 = 114/152 = 117/156 = 120/160
