3x+4y=5
2x+3y=

-2(3x+4y)=5(-2)
3(2x+3y)=4(3)

-6x-8y=(-10)
6x+9y=12

Add the equations

-6x-8y=(-10)
+ 6x+9y=12
-----------------
0x+y=2
y=2

Substitue y into an equation

6x+9(2)=12
6x+18=12
6x=-6
x = -1
y = 2

For how many minutes did Lynn run at a greater speed than Kael? 12 17 23 28.
Archy [21]

Answer:

<u><em>28 minutes.</em></u>

Step-by-step explanation:

We can see from our graph that 12 minutes after starting the race Lynn left Kael behind and he ran at a greater speed till the race ended after 40 minutes.

To find total number of minutes Lynn ran faster than Kael we will subtract 12 from 40.

Therefore, Lynn ran at a greater speed than Kael for <u><em>28 minutes.</em></u>
