Answer:
=−4√2
I got this when simplified.
You have to set up a system of equations
x+y=104
3x-y=104
Sodas = 78
Hotdogs = 26
Answer:
192
Step-by-step explanation:
The sum of the first 3 terms of the A. P is
a + a + d + a + 2d = 18, that is
3a + 3d = 18 ← substitute a = 4
12 + 3d = 18 ( subtract 12 from both sides )
3d = 6 ( divide both sides by 3 )
d = 2
Thus the first 3 terms are
4, 6, 8 and their product = 4 × 6 × 8 = 192
Answer:
34.4x
Step-by-step explanation:
18 x 4 = 72
(9 x 2) x 4 = 72
9 x (2 x 4) = 72
