Answer:
N = 85
Step-by-step explanation:
(236 + 542)+N = 863
778 + N = 863
N = 863 - 778
N = 85

yep :)
Step-by-step explanation:
Answer:
x = -3/2 x=2
Step-by-step explanation:
2x² - x-6=0
Factor
(2x ) (x ) =0
6 = 2*3
2*-2 +3 = -1
(2x +3 ) (x -2 ) =0
2x+3 =0 x-2 =0
2x = -3 x=2
x = -3/2 x=2
10 - 4 2/3
First, we convert mixed fraction into improper fraction.
4 2/3 = ((4*3)+2)/3 = 14/3
In subtracting fractions:
1) Both must have the same denominator.
10 is 10/1 and 14/3 have different denominators.
2) Once they have the same denominator, then subtraction may be performed.
10 - 14/3 = 10 * 3/3 - 14/3 = 30/3 - 14/3 = 16/3
3) 16/3 must be simplified.
16/3 = 5 1/3
10 - 4 2/3 = 5 1/3
The first one is 64, the second 250, the third 520, and the fourth is 96
