813. When you are given a problem like this, you can answer it by using the
MDAS technique. MDAS stands for multiplication, division, addition, and
subtraction. Since you are following the MDAS technique, you are asked to answer
the equation based on MDAS order. To put this simply, look at the example
below:
20x40+3x9/3+4
800+3x9/3+4
800+27/3+4
800+9+4
809+4
813</span></span>
You can clearly see the MDAS order by following the bold
text.
1. distribute a 1 to the 12 and 8a
2. you'll get 15+ 12 +8a
3. add the like terms(15 and 12)
4. your final answer will be 27+8a
Answer:
x = 0.2(10^y/a).
Step-by-step explanation:
y = alog(5x)
y = log(5x)^a) By the definition of a log:
(5x)^a = 10^y
5x = (10^y) ^ 1/a
x = 0.2(10^y/a)

Answer:
A, E
Step-by-step explanation:
You are correct that the appropriate relationship is ...
g = 0.4t . . . . choice A
You are also correct that an equivalent relationship is ...
t = 2.5g . . . . choice D
However, when we say gallons are proportional to seconds, we usually expect that to be written ...
g = kt . . . . for some value of k
__
We note that another equivalent is ...
g = 2/5t . . . . choice E
The appropriate choices are probably A and E. Choice D might be argued to be correct, but you could very well lose that argument to someone who prefers a "g = " form of the relationship.
