Answer: b / 3 = d / 2

Step-by-step explanation:

(b + 6)/3 = (d + 4)/2

(b / 3) + (6 / 3) = (d + 4)/2

(b / 3) + 2 = (d + 4)/2

Subtracting 2 from both sides,

(b / 3) + 2 - 2 = ((d + 4)/2) - 2

or, b / 3 = ((d + 4)/2) - 2

or, b / 3 = (d / 2) + ( 4 / 2 ) - 2

or, b / 3 = (d / 2) + 2 - 2

or, b / 3 = d / 2

So,

b/3 is equal to d/2.

What is the common difference of the sequence 8, 4, 0, -4, -16?

soldier1979 [14.2K]

$\large \mathfrak{Solution : }$

Common difference of an Arithmetic progression can be found out by subtracting the preceding term from that given term.

i.e

$common \: \: difference = 4 - 8$
$common \: \: difference = - 4$

therefore, the common difference of the above Arithmetic progression is -4 .

John drove to Daytona Beach, Florida, in hours. When he returned, there was less traffic, and the trip took only hours. If John

Question: John drove to a distant city in 5 hours.

When he returned, there was less traffic and the trip took only 3 hours.

If John averaged 26 mph faster on the return trip, how fast did he drive each way

Answer:

For the first trip he drove at a speed of 39 mph

For the second trip he drove at a speed of 65 mph

Step-by-step explanation:

Let the distance for both journey be Z because they are equal.

Let the speed for the first journey be X

Let the speed of the second journey be Y

Formula for speed = distance ÷ time

For the first journey the speed X = Z ÷ 5

For the second journey the speed Y = Z ÷ 3

Since John averaged 26 mph faster in the second trip than the first trip due to traffic, it means that the difference in speed between the first & second trip is 26 mph

Difference in speed = (Z÷3) - (Z÷5) = 26

subtracting both results to (5Z-3Z) ÷ 15 = 26

Upon cross multiplication

2Z = 390

Z = 390÷2 = 195 miles

Therefore speed for first journey = 195 ÷ 5 = 39 mph

Speed for second journey = 195 ÷ 3 = 65 mph

To verify, 65 - 39 = 26 mph

Joy recorded the distances she walked each day for five days. How far did she walk in 5 days?

oee [108]

Joy walked 1/3 units (miles? kilometers? it doesn't matter actually) in 3 of the 5 days. So, walking 1/3 units for three days tallies up to

$\dfrac{1}{3}\cdot 3 = 1$

If we add the day when she walked 1/2 units and the day she walked 2/3 units, we get

$1+\dfrac{1}{2}+\dfrac{2}{3} = \dfrac{6+3+4}{6} = \dfrac{13}{6}$
