Ben participated in a race. During the first half of the race, he walked 3 miles and ran at a rate of 5 miles per hour for x hou

rs. During the second half of the race, he walked for 2 miles and ran at a rate of 5.5 miles per hour for x hours. What equation could you write to solve for the number of hours Ben ran during each half of the race? Let y represent the number of miles in half the race. Write two equations, one for the first half of the race and one for the second half. How could you transform these two equations to be the same as the original equation you wrote to solve for x? What do you think this means about solving for the variables in a situation represented by two equations?

Answer:

y = 5x + 3

y = 5.5x + 2

0.5x = 1

x = 2

y = 13

anyways what I think this means for the variables is x is equal to x in the second equation and y is equal to y in the second equation

Y = 5x + 3
y = 5.5x + 2
0.5x = 1
x = 2

How many miles per hour is this? (one furlong is 18 mile, and a fortnight is 14 days. a furlong originally referred to the lengt
WITCHER [35]

the complete question is

While driving in an exotic foreign land you see a speed limit sign on a highway that reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is 1/8 mile, and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow.)

Step 1

<u>convert (furlongs per fortnight) to (miles per fortnight)</u>

180,000 furlongs per fortnight=180,000*(1/8)=22,500 miles per fortnight

Step 2

<u>convert miles per fortnight to miles per hour</u>

1 day=24 hour

14 day=24*14=336 hours

22,500 miles per fortnight=22,500/336=66.96 mph

therefore

<u>the answer is</u>

66.96 mph

Two friends went fishing on a lake. One friend's lure went 23 feet below the lake's surface, while the other friend's lure sank
serg [7]

Answer:

Distance = 58\ feet

Step-by-step explanation:

Represent the lure's difference with A and B;

A = 23\ feet

B = 81\ feet

Required

Determine the difference in depth between the lure's depth

The distance is calculated as follows;

Distance = B - A

Substitute 23 feet for A and 81 feet for B

Distance = 81\ feet - 23\ feet

Distance = 58\ feet

<em>Hence, the distance between both lure's is 58 feet</em>

Kevin wanted to go snowboarding for his vacation. Explain how he could make his decision regarding whether to go to Resort A or
Tcecarenko [31]

Answer:

Resort A has more consistent snowfall, so it shows less variation. However, the snowfall for Resort B has a higher median, and the interquartile range is higher (not larger), so it is more likely that Kevin will find a good snowfall at Resort B.

Thanks:) I just did it edg

Nina = x coins

Clayton = 6x - 5 coins

Expression for the total number of coins Nina and Clayton have altogether.

Nina + Clayton

= x + (6x - 5)

= x + 6x - 5

= 7x - 5

The correct answer and expression is 7x - 5
