Answer:
Step-by-step explanation:
10 4/5 = 10.8
10 7/10 = 10.7
Frankie did not swim the longest distance.
Gus did.
10.8>10.7
2p+6a=$14
3p+9a=$21
3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations
2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14
this zeroes out...
Answer:
1680 in^3
Step-by-step explanation:
SO you got the triangle
24*10=240
240/2=120
now we just need to find the area
There is a formula but I think this is easier
So theres a rectangle with a length of 14
So if you think of the triangle as the base, you just need 14 triangles stacked up to make up the volume
So 120*14=1680
So the volume is 1680
Answer:
-21
Step-by-step explanation:
I assume this is a 2 by 2 matrix.
determinant = -5 * 4 - 1 * 1 = -20 - 1 = -21
The number of solutions of the system of equations is 904 086
