Answer:

\large\boxed{j=-\dfrac{3}{2}\to j=-1\dfrac{1}{2}\to j=-1.5}

Step-by-step explanation:

12.6j+8=10.2j+4.4\qquad\text{subtract 8 from both sides}\\\\12.6j+8-8=10.2j+4.4-8\\\\12.6j=10.2j-3.6\qquad\text{subtract}\ 10.2j\ \text{from both sides}\\\\12.6j-10.2j=10.2j-10.2j-3.6\\\\2.4j=-3.6\qquad\text{divide both sides by 2.4}\\\\\dfrac{2.4j}{2.4}=\dfrac{-3.6}{2.4}\\\\j=-\dfrac{3.6\cdot10}{2.4\cdot10}\\\\j=-\dfrac{36}{24}\\\\j=-\dfrac{36:12}{24:12}\\\\j=-\dfrac{3}{2}\to j=-1\dfrac{1}{2}\to j=-1.5

Aysha ran 400 meters in 10 minutes on Monday and she ran 825 meters in 25 minutes on Tuesday. On which day she ran faster?
LiRa [457]

Answer:

Monday

Step-by-step explanation:

Day 1 (Monday):

10 minutes to seconds: 10 x 60 = 600 seconds

\frac{400m}{600s}= 0.67 m/s

Therefore day 1 she ran at 0.67 m/s

Day 2 (Tuesday):

25 minutes to seconds: 25 x 60 = 1500 seconds

\frac{825m}{1500s} = 0.55 m/s

Therefore day 2 she ran at 0.55 m/s

She was faster day 1 (Monday)!
