Hello there! The radius is 7.

Remember that the radius is half the diameter. If you take half of 14 (aka divide by 2) you get 7, making this your radius.

I hope this helps and have a great day! :)

If you distribute, then you get -10x+7.5

Note how -2.5 times 4x = -10x and how -2.5 times -3 = 7.5

The idea is that you multiply the outer term (-2.5) by each term inside

To reach a vacation spot, the Jones family first traveled by plane and then drove the

navik [9.2K]

The distance flown by plane is 750 kilometers.

Step-by-step explanation:

Let,

Distance traveled by plane = x

Distance traveled by car = y

Total distance = x+y

According to given statement;

The distance by car was 125 kilometers less than the distance by plane.

y = x - 125 => x=y+125 Eqn 1

The total distance was 500 kilometers less than three times the distance traveled by car.

Total distance = 3y - 500

x+y=3y-500 Eqn 2

Putting value of x from Eqn 1;

$(y+125)+y=3y-500\\y+y+125=3y-500\\2y=3y-500-125\\2y-3y=-625\\-y=-625\\y=625$

Putting y=625 in Eqn 1

$x=625+125\\x=750$

The distance flown by plane is 750 kilometers.
