Two towns are 1300 miles apart. A group of hikers starts from each town and walks down the trail toward each other. They meet af
Leto [7]
240(v+2.5)=1300-240v

240v+600=1300-240v

480v=1900

v=95/24

v-2.5=v-5/2

95/24-60/24=35/24

So the faster group travels at 95/24 mph (≈3.96 mph) and the slower group travels at 35/24 mph (≈1.46mph)

check...

240(95/24)=950 miles from the origin...

1300-240(35/24)=950 miles from the origin...

Can you step by step solve 20x+12=4x-16
Murljashka [212]

Answer:

x = - \frac{7}{4}

Step-by-step explanation:

Given

20x + 12 = 4x - 16 ( subtract 4x from both sides )

16x + 12 = - 16 ( subtract 12 from both sides )

16x = - 28 ( divide both sides by 16 )

x = \frac{-28}{16} = - \frac{7}{4} [ = - 1.75 ]
