It takes \frac{4}{5} hours or 48 minutes before they meet if their houses are 4 miles apart

<em><u>Solution:</u></em>

Let "t" be the number of hours it will take them to meet

Walking speed of Fred = 3 miles per hour

Walking speed of John = 2 miles per hour

Distance between their house = 4 miles

<em><u>Distance is given by formula:</u></em>

Distance = speed x time

Fred distance = walking speed of Fred x time taken

Fred distance = 3t

John distance = walking speed of John x time taken

John distance = 2t

Therefore,

3t + 2t = 4

5t = 4

t = \frac{4}{5} hours

We know that,

1 hour = 60 minutes

Therefore,

\frac{4}{5} \text{ hours } = \frac{4}{5} \times 60 \text{ minutes } = 48 minutes

Thus it takes \frac{4}{5} hours or 48 minutes before they meet

PLEASE HELP ME ASAP! I need to know the 3 equations to solve for the different types of points. ​
kiruha [24]

Answer:

f = 0

x > 2y

x ≤ 8

S ≥ 18

Step-by-step explanation:

Let 'f' represent the number of free throws.

Let 'x' represent the number of 2 - point baskets.

Let 'y' represent the number of 3 - point baskets.

Let S represent the Season high.

1) Ryan says he did not shoot any free throws.

⇒ f = 0

2) 2 - point baskets more than twice the number of 3 - point baskets.

⇒ x > 2y

3) Number of two points is less than or equal to 8.

⇒ x ≤ 8.

4) Last Season high, he had scored 18 points. Note that the problem says, Ryan equaled or bettered than last season high. That means he should got at least 18 points this season. So, the equation would be:

S ≥ 18

What is the solution of the linear equation? LaTeX: 5k\:+\:3.8\:=\:3k\:+\:95 k + 3.8 = 3 k + 9 Group of answer choices 26 6.4 .0
lakkis [162]

Answer:

k = 2.6

Step-by-step explanation:

Given

5k + 3.8 = 3k + 9

Required

Solve

5k + 3.8 = 3k + 9

Collect like terms

5k -3k+ 3.8 = 3k -3k + 9

2k+ 3.8 = 9

Subtract 3.8 from both sides

2k+ 3.8 - 3.8= 9 - 3.8

2k= 9 - 3.8

2k = 5.2

Divide through by 2

k = 5.2/2

k = 2.6
