<span>Sheila can ride her bicycle 6000 meters in 15 minutes.
Forming that into a ratio, that will be 6000 : 15
Doing the proportion for 2 minutes.
6000 : 15 = X : 2
Doing the computation.
6000 / 15 = X / 2
15X = 2 * 6000
15X = 12000
X = 800
So Sheila covered a total of 800 meters in 2 minutes.</span>
<span>2x + y = 3
a: 5
x - 2y = -1
a: 2
If equation one is multiplied by 2 and then the equations are added, the result is _____.
3x = 2 this is the answer
3x = 5
5x = 5</span>
3x - 36 + 2x + 26 = 180
5x - 10 = 180
5x = 180 + 10
5x = 190
x = 190/5
x = 38 <==
