Answer:
35 slices originally
Step-by-step explanation:
1. 0.4 means 40%
2. if 14 slives equal 40% we need to divide by 4 to find 10%
3. 14 divided by 4 is 3.5
4. then we multiply 3.5 (10% of the cake) by 10 because 10•10=100(%)
3.5•10 equals 35 slices

Answer:
(2, -4)
Step-by-step explanation:
1/2 x + 3/4 y = -2
2/3 x + 5/6 y = -2
4 (1/2 x + 3/4 y = -2 ) = -2(2x + 3y = -8) Multiply by -2 to eliminate the x's
6 (2/3 x + 5/6 y = -2) = (4x + 5y = -12)
<u> -4x - 6y = 16 </u> combine with the 2nd equation
-1y = 4
y = -4
plug -4 in for y to find x in either equation
1/2x + 3/4 (-4) =-2
1/2x - 3 = -2
1/2x = 1
x = 2
(2, -4)
