marishachu [46]

Let us say that:

x = mass from Earl Grey Tea

y = mass from Orange Pekoe Tea

 

So that:

x + y = 600

and that:

6 x + 4 y = 4.5 * 600

6 (600 – y) + 4 y = 2700

3600 – 6y + 4y = 2700

-2y = -900

y = 450 pounds

x = 600 – 450 = 150 pounds

 

Answer:

<span> Earl Grey Tea = 150 pounds</span>

<span>Orange Pekoe Tea = 450 pounds</span>

Can u please answer this question

One Way:
We can change the mixed number to a decimal for comparing.

1\frac{1}{4} m = \frac{5}{4} m = 1.25 m

1.4 m     >    1.25 m
Darren   >     Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

1\frac{1}{4} = \frac{5}{4} (Luke)
1.4 = \frac{7}{5}                               (Darren)
We need a common denominator to compare
\frac{5*5}{4*5}       (Luke)
\frac{7*4}{5*4}       (Darren)
\frac{25}{20}          (Luke)
\frac{28}{20}          (Darren)

\frac{28}{20}  >   \frac{25}{20}
        Darren           >            Luke
  
By:
\frac{28}{20} - \frac{25}{20} = \frac{3}{20}
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
