The equation $y+4x=100$y+4x=100 represents your distance y (in meters) from the finish line x seconds after you begin your leg of a relay race. The equation $y+3.7x=94$y+3.7x=94 represents your opponent's distance from the finish line. How far do you need to run to catch up with your opponent?

Given:

Your distance y (in meters) from the finish line x seconds after you begin your leg of a relay race is

Opponent's distance is

To find:

The distance you need to run to catch up with your opponent.

Solution:

We have,

           ...(i)

         ...(ii)

Subtract (ii) from (i), we get

Divide both sides by 0.3.

Put x=20 in (i).

They will meet at (20,20). It means at 20 meters from the finish line after 20 seconds from the beginning.

Put x=0 in (i), we get

It means, initially the total distance you and finish line is 100 meters.

You will catch your opponent 20 meter from the finish line. So,

Therefore, you need to run 80 meters to catch up with your opponent.

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
