All u have to do is find what variable will make each statement true, I'll do one so u would get what I mean,

61. x + 13.5 < 19, this could be anything under 19 since it's supposed to be greater, I chose 5 + 13.5 < 19 which is 18.5 < 19

The number goes from 13.5 to 19 you could do it like decimals, start it from 13 then go on like this, 13,13.5,14,14.5,15,15.5,16,16.5,17,17.5,18,18.5,& 19.

a) On Wednesday, Harry sold 3 times as many candy bars as on Tuesday. On Thursday, he sold 5 times as many bars as on Wednesday.

Alborosie

Answer:

Tues=8 Weds=24 Thurs=120

Step-by-step explanation:

The question can be modeled by the equation x+3x+15x=152

x is the amount sold on tuesday, 3x is 3 times the amount sold on tuesday so it represents wednesday and 15x represents thursday as it is 5 times the amount sold on wednesday.

Now we just need to solve for x to figure out how many he sold each day.

x+3x+15x=19x

19x=152

x=152/19

x=8

To find the amount sold on each day just mulitiply x by the coefficient

Tuesday = x = 8

Wednesday = 3x = 3*8 = 24

Thursday = 15x = 15*8 = 120

Write the expressions without using log. Can someone please help with this?

$\bf \textit{logarithm of factors}\\\\
log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)
\\\\\\
\textit{Logarithm of rationals}\\\\
log_{{ a}}\left( \frac{x}{y}\right)\implies log_{{ a}}(x)-log_{{ a}}(y)
\\\\\\
\textit{Logarithm of exponentials}\\\\
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\\\\
-------------------------------$

$\bf log(m^3n)\implies log(m^3)+log(n)\implies 3log(m)+log(n)
\\\\\\
\boxed{3k+v}
\\\\\\
log\left(\cfrac{m}{n^3} \right)\implies log(m)-log(n^3)\implies log(m)-3log(n)
\\\\\\
\boxed{k-3v}$
