let's firstly, convert the mixed fraction to improper fraction, and then subtract.


\bf \stackrel{mixed}{2\frac{3}{4}}\implies \cfrac{2\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{11}{4}}&#10;\\\\[-0.35em]&#10;\rule{34em}{0.25pt}\\\\&#10;\cfrac{11}{4}-\cfrac{2}{3}\implies \stackrel{\textit{our LCD will be 12}}{\cfrac{(3)11-(4)2}{12}}\implies \cfrac{33-8}{12}\implies \cfrac{25}{12}\implies 2\frac{1}{12}

How do you solve these problems?
Rzqust [24]
A)

\bf log_4(x)=3\\\\&#10;-----------------------------\\\\&#10;log_{{  a}}{{  a}}^x\implies x\qquad \qquad &#10;\boxed{{{  a}}^{log_{{  a}}x}=x}\impliedby &#10;\begin{array}{llll}&#10;\textit{we'll use this}\\&#10;\textit{cancellation rule}&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;4^{\cfrac{}{}log_4(x)}=4^3\implies x=4^3

b)

\bf 3^{2y}=81\qquad &#10;\begin{cases}&#10;81=3\cdot 3\cdot 3\cdot 3\\&#10;\qquad 3^4&#10;\end{cases}\implies 3^{2y}=3^4\impliedby &#10;\begin{array}{llll}&#10;\textit{same base}\\&#10;exponents\\&#10;must\ be\\&#10;the\ same&#10;\end{array}&#10;\\\\\\&#10;2y=4\implies y=\cfrac{4}{2}\implies y=2

5. Yesterday your friend made 1 gallon of dark pink paint using the information in the table.
Oxana [17]

Our friend's mistake when wanting to make a new mixture of pink paint is that she is only going to add 2 parts of white paint, the correct formula would be 3.

<h3>How to calculate how much paint you need to make 3 gallons of Pink paint?</h3>

To mix 3 gallons of pink paint we must take into account the following information:

  • 1 gallon of pink paint is equal to 3 parts red paint and 1 part white paint.

To find out how many parts we need to prepare 3 gallons of pink paint we must multiply the mix values for a gallon by 3.

Red paint:

  • 3 x 3 = 9

White paint:

  • 1 x 3 = 3

Based on the above, we need to use 3 parts white paint and 9 parts red paint to make 3 gallons of pink paint.

Note: This question is incomplete because the graph is missing. Here is the graph.
