Answer:
Experimental study
Step-by-step explanation:
14.99 x 12 = 179.88
179.88 x 2 = 359.76.
She would spend 359.76 in 2 years
8v + 8b = 240
4v + b = 54....multiply by -2
-------------------
8v + 8b = 240
-8v - 2b = - 108 (result of multiplying by -2)
------------------add
6b = 132
b = 132/6
b = 22 <== buses hold 22 students
4v + b = 54
4v + 22 = 54
4v = 54 - 22
4v = 32
v = 32/4
v = 8 <== vans hold 8 students
Answer:
x = 2.564 ( to 3 dec. places )
Step-by-step explanation:
Using the rule of logarithms
log
⇔ n logx
Given
= 62 ( take the ln of both sides )
ln
= ln 62, that is
x ln5 = ln 62 ( divide both sides by ln 5 )
x =
≈ 2.564
12/34 = 6/17. That's not even half a pizza. I think you should order one...
