We have that
1/16 = 64<span>^x
applying log both sides
log(1/16)=log(</span>64^x)
log 1-log16=x*log64
-log 16=x*log 64
divide by log 64 both sides
x=-log 16/log 64
log 16=log 2^4-----> 4*log 2
log 64=log 2^6-----> 6*log 2
-log 16/log 64=(-4*log 2)/(6*log 2)-----> -4/6------> -2/3
the answer is
x=-2/3
Answer:
if you mean use the distributive property, you would multiply each term within the parentheses by -6, giving you -6(x) + -6(6), giving you -6x-36
Step-by-step explanation:
<h3>Answer:</h3>
A. 5/4 . . . or . . . 1.25
B. see below
<h3>Explanation:</h3>
B. The dilation factor is the ratio of the image lengths to the original lengths. Here, for example, that could be
... d = E'F'/EF = (-4-(-9))/(-2-(-6))
... d = 5/4
A. The result of the calculation of part B is 5/4 = 1.25.
Answer:
small = 35 pounds
large = 45 pounds
Step-by-step explanation:
Let x = large boxes
y = small boxes
two equations can be derived from the question
x + y = 80 equation 1
60x + 65y = 4975 equation 2
multiply equation 1 by 60
60x +60y = 4800 equation 3
subtract equation 2 from 3
5y = 175
y = 35
substitute for y in equation 1
x + 35 = 80
x = 80 - 35
x = 45
N= the # of books
So you're trying to find n and you have the cost for the printed books, which is 15,000, so you would set up your equation like this:
15,000=500+10n
Subtract 500 from each side
14850=10n
Divide by 10
n=1,485 books are printed
