Answer:

$x(x+5)=x^2-3x+8$

Step-by-step explanation:

There are infinite cases of equations with exactly one real solution. To create something worth the space, this one should suffice

$x(x+5)=x^2-3x+8$

Operating

$x^2+5x=x^2-3x+8$

Simplifying

$5x=-3x+8$

Joining like terms

$8x=8$

Solving

x=1

Testing the result

$1(1+5)=1^2-3(1)+8=>6=6$

A fudge recipe calls for 2 1/3 cups of flour for every 3/4 cups of cocoa powder. Could you increase the recipe proportionately b

ryzh [129]

same as before, is the proportion of one, the same as the other? let's do the same here without much fuss.

$\bf \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}}
~\hfill
\stackrel{mixed}{4\frac{2}{3}}\implies \cfrac{4\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{14}{3}}$

$\bf \stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\cfrac{~~2\frac{1}{3}~~}{\frac{3}{4}}=\cfrac{~~4\frac{2}{3}~~}{1\frac{1}{2}}\implies \cfrac{~~\frac{7}{3}~~}{\frac{3}{4}}=\cfrac{~~\frac{14}{3}~~}{\frac{3}{2}}\implies \cfrac{7}{3}\cdot \cfrac{4}{3}=\cfrac{14}{3}\cdot \cfrac{2}{3}\implies \cfrac{28}{9}=\cfrac{28}{9}~~\textit{\Large \checkmark}$

alexgriva [62]

Answer:

Jocelyn = 8 Miles an Hour

Micheal-Anthony = 6 Miles a Hour

Jocelyn Run Faster than Micheal-Anthony.

Step-by-step explanation:

Important information:

Michael-Anthony runs 3 Miles in 20 Minutes.

Jocelyn Runs 4 Miles in 30 Minutes.

Continues at pace for 1 Hour.

Questions that Need to be Answer:

How many miles does each person each person run in an hour?

Who runs faster?

Explanation/Solution:

So, We know that 1 Hour = 60 Minutes and three 20 minutes equal 60 Minutes also known as 1 Hour..

Since, three 20 minutes equal 1 Hour that means

Micheal-Anthony Run 6 Miles a Hour adding the 20 Minutes equal 9 Miles

Hence, Micheal-Anthony Run 9 Miles..

We know that 1 Hour = 60 Minutes and two 30 Minutes equal 60 Minutes also known as 1 Hour..

Since, two 30 Minutes equal 1 Hour that means

Jocelyn Run 8 Miles a Hour adding the 30 Minutes equal 12 Miles

Hence, Jocelyn Run 12 Miles..

For these Reason, You can tell that Jocelyn Run 8 Miles an Hour and Micheal-Anthony Run 6 Miles a Hour and Jocelyn Run Faster than Micheal-Anthony.
