GalinKa [24]

Car A travels 180miles in 7 hours
Car A travels 25.7 miles an hour because 180/7 = 25.7

Car B travels 350 miles in 4 hours
Car B travels 87.5 miles an hour because 350/4= 87.5

Car C travels 584 miles in 15 hours
Car C travels 38.9 miles an hour because 584/9 = 38.9

Car B has the fastest average speed

Find the distance between the two points rounding to the nearest tenth (if needed)

Ede4ka [16]

Answer:

6.3 units (nearest tenth)

Step-by-step explanation:

$\boxed{Distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Using the formula above,

distance between (-8, 6) and (-6, 0)

$= \sqrt{ {[ - 8 - ( - 6)]}^{2} + {(6 - 0)}^{2} }$

$= \sqrt{ {( - 8 + 6)}^{2} + {(6 - 0)}^{2} }$

$= \sqrt{ {( - 2)}^{2} + 6^{2} }$

$= \sqrt{4 + 36}$

$= \sqrt{40}$

= 6.3 units (nearest tenth)

(n-2) x 180

(10-2) x 180

2(10r-7)-2(1+10r)=-r+2r

DerKrebs [107]

Answer:

r = -16

Step-by-step explanation:

We will use "distributive" property and "adding like terms" concepts in solving for the unknown variable "r".

The distributive property is:

a(b+c) = ab + ac

So

2(10r-7) = 20r - 14

also

-2(1+10r) = -2 - 20r

So, our equation becomes:

$2(10r-7)-2(1+10r)=-r+2r\\20r-14-2-20r=-r+2r$

Now we add like terms and move variables (r) to one side and numbers to another. Like terms mean:

3r + 5r = (3+5)r = 8r

So, we have:

$20r-14-2-20r=-r+2r\\-16=r\\r=-16$

So,

the value of r is -16
