Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
- 2x + 3y = 7
- 4x + 9y = 27

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
