Express the pair of fractions using the least common denominator of the two. 2/3, 1/4

Fed [463]

Answer:

8/12, 3/12

Step-by-step explanation:

Least common multiple for 3 and 4 is 12. So the denominator should be 12.

For the fraction 2/3, multiply the numerator and denominator by 4 so you will get :

2/3 * 4/4 = 8/12

For the fraction 1/4, multiply the number and denominator by 3 so you will get:

1/4 * 3/3 = 3/12

The sum of 4 and y divided by 5 equal to 9. Find the value of y. pls a better solution

rosijanka [135]

Answer:

y=41

Step-by-step explanation:

Let us start by writing an equation. 4 plus y divided by 5 equals to 9 :

$\frac{4+y}{5}=9$

Great! Now let us solve for the variable, y, by isolating the terms:

$4+y=45\\y=41$

I hope this helps! Let me know if you have any questions :)

$(\stackrel{x_1}{4}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{4}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{4}}}\implies \cfrac{-6}{-3}\implies 2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{4}=\stackrel{m}{2}(x-\stackrel{x_1}{4}) \\\\\\ y-4=2x-8\implies y=2x-4$
