Step-by-step answer:
e^(5x) ≈ 4768 [ note proper parentheses to make the problem unambiguous]
Take log (e) on both sides
log(e^(5x)) = log(4768) =>
5x = log(4768)
x = log(4768)/6
[ = 1.6939, approximately ]
4cans/$6 = 13cans/$x now cross multiply and solve for x
Answer:
4
Step-by-step explanation:
Use the first equation cause -2 < -1
-2(-2) = 4
Answer:
x = 31
Step-by-step explanation:
AC=BD
3x+7 = 131-x
Subtract 7 from both sides
3x = 124-x
Add x to 3x
4x = 124
Divide by 4
x = 31
Check:
3(31)+7 = 131 - 31
Mulitply 3 times 31 / subtract 131 and 31
93+7 = 100
Add 93 to 7
100 = 100
