Aya and Mary are 12 miles apart on a path when they start moving toward each other.
Aya runs at a constant speed of 5 miles per hour, and Mary walks at a constant speed
of 3 miles per hour. How long does it take until Aya and Mary meet?
Pleaseee help

Answers

Answer:

1.5 hours

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Aya and Mary distance = 12 miles

Let, meeting point from Aya = Z miles

So, Aya covers Z miles to reach Mary.

Hence, Mary covers (12 - Z ) miles to reach Aya

Here, Time = [tex]\frac{Distance}{Speed}[/tex]

Aya = [tex]\frac{Z}{5}[/tex]

Mary = [tex]\frac{12-Z}{3}[/tex]

If, same time taken, then we can solve by following method,

[tex]\frac{Z}{5} = \frac{12-Z}{3}[/tex]

By solving the equation, we get

Z = 60 ÷ 8

Or Z = 7.5 miles

Hence, time taken for both to meet = 7.5 ÷ 5

= 1.5 hours

Answers

Answers:

Solving for x on the question - 2x + 3y = 32  |  Answer : x =  [tex]\frac{-3}{2}[/tex]⁻y + 16

Solving for y on the question - 2x + 3y = 32  |  Answer : y = [tex]\frac{-2}{3}[/tex]x + [tex]\frac{32}{3}[/tex] Solving for x on question - 5x - 4y = -81 |Answer : x =  [tex]\frac{4}{5}[/tex]y + [tex]\frac{-81}{5}[/tex]

Solving for y on question - 5x - 4y = -81 |Answer : y =  [tex]\frac{-5}{4}[/tex]x + [tex]\frac{81}{4}[/tex]Step-by-step explanation:

(Solving for x on question - 2x + 3y = 32)

2x + 3y = 32

Step 1: Add -3y to both sides.

2x + 3y + −3y = 32 + −3y

2x = −3y + 32

Step 2: Divide both sides by 2.

[tex]\frac{2x}{2}[/tex]  = [tex]\frac{-3y+32}{2}[/tex]

x =  [tex]\frac{-3}{2}[/tex]⁻y + 16                                                                                                                

(Solving for y on question - 2x + 3y = 32)

2x + 3y = 32

Step 1: Add -2x to both sides.

2x + 3y + −2x = 32+ −2x

3y = −2x + 32

Step 2: Divide both sides by 3.

[tex]\frac{3y}{3}[/tex] =  [tex]\frac{-2x+32}{3}[/tex]

y = [tex]\frac{-2}{3}[/tex]x + [tex]\frac{32}{3}[/tex]                                                                                                          

(Solving for x on question - 5x - 4y = -81)

5x − 4y = −81

Step 1: Add 4y to both sides.

5x − 4y + 4y = −81 + 4y

5x = 4y − 81

Step 2: Divide both sides by 5.

[tex]\frac{5x}{5}[/tex] =  [tex]\frac{4y-81}{5}[/tex]

x =  [tex]\frac{4}{5}[/tex]y + [tex]\frac{-81}{5}[/tex]                                                                                                              

(Solving for y on question - 5x - 4y = -81 )

5x − 4y = −81

Step 1: Add -5x to both sides.

5x − 4y + −5x = −81 + −5x

−4y = −5x − 81

Step 2: Divide both sides by -4.

[tex]\frac{-4y}{-4}[/tex] = [tex]\frac{-5x-81}{-4}[/tex]

y =  [tex]\frac{-5}{4}[/tex]x + [tex]\frac{81}{4}[/tex]

Ron solved the equation (2/3)r = 12 by multiplying both sides by 2/3 and he got r = 8. Explain the error that Ron made and then find the correct value for r

Answers

Answer:

Ron multiplied with the wrong number. He should have multiplied with 3/2 (the reciprocal of 2/3), which would have made the 2/3 a 1, thus isolating the r.

r = 18

Step-by-step explanation:

(2/3)(3/2)r = 12

r = 12(3/2)

r = 18
