Answer:
not possible.
Step-by-step explanation:
number of invitations luanne has to address after x days = 120-15x
number of invitations Darius has to address after x days = 120 + 15(7-x)
so, if the number of invitations should be the same for both of them,
we have to equate their number of invitations
120-15x = 120 + 15(7-x)
subtracting 120 from both the sides,
-15x = 15(7-x) = 105 -15x
adding we 15x on both sides, we wont find any solution for x.
so, this isnt possible or the question must be wrong.
Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
Answer:
x=158
Step-by-step explanation:
109=-x+267
-267 -267
-158=-x
x=158
(also i noticed part of your question says x=(?)*5 and 31.6*5 is 158 so that would be 31.6)
Answer:
No, Dale Isn't correct because 3:5 is greater than 2:10
Step-by-step explanation:
3:5 and 2:10 is the same as in 
and 
First Find the least common denominator or LCM of the two denominators:
LCM of 5 and 10 is 10
Next, find the equivalent fraction of both fractional numbers with denominator 10
For the 1st fraction, since 5 × 2 = 10,
Likewise, for the 2nd fraction, since 10 × 1 = 10,
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
Hence, is <u>Greater than </u>
Hence, 3:5 is <u>Greater than </u>2:10
