Car A went 60 km in 3/4 hour while a car B went 80 km in 4/5 hour. Which car was faster? How many times faster?
laila [671]

Answer:

Car B would go faster because it goes 20 more km and that would mean that it drove that fast in 48 minutes, for 1/5 of 60 minutes (1 hour) is 12 minutes. As for Car A, that goes 60 km is 45 minutes. The only time difference between the two is 3 minutes, which is 3 minutes longer for Car B, although it goes faster. Car B also goes 20 more km faster.

**Also any Brainliests from the questioner would help :)

*I do hope that this helps!

Write down the reciprocal of<br> 1/3
Leokris [45]
<h2><u>RECIPROCAL</u></h2>

<h3>ANSWER: </h3>
  • \boxed{ \bold{3 \: \: \:  or  \: \:  \:  \frac{3}{1} }}

<h3>EXPLANATION:</h3>

As we can see above, it's clear that 3 and 1/3 are reciprocals of each other.

And we can find the reciprocal of 1/3 by forming a fraction and to multiply the numerator and denominator by 3.

  • \\ \large  \tt \:  \frac{1 \times 3}{ \frac{1}{3} \times 3 }  =  \bold{ \frac{3}{1}  = 3} \\ \\

Hence, 3/1 or 3 is the correct answer.

Solve the equation for the given variable.<br> Bx+Cy=D<br><br> Solve for y
WARRIOR [948]
Bx + Cy = D

Solve for y . .  .

*subtract Bx from both sides

Bx - Bx + Cy = D - Bx

Cy = D - Bx

*now divide both sides by C

Cy/C = (D - Bx)/C

Cy/C = D/C - Bx/C

y = D/C - (B/C)x

<u><em>y = -(B/C)x + D/C</em></u>
