Step-by-step explanation:
450 - 396 = 54
(54/450) * 100% = 12%
Hence the decrease is 12%.
The product<span> of </span>two consecutive negative integers<span> is 462. Determine the two </span>integers<span>. ... Since this is a quadratic equation, we'll </span>get<span> one side equal to zero (by subtracting 462 from each side): ... Since </span>20*20<span> = 400 we can start near there.</span>
Answer:
Step-by-step explanation:
x+2y=3
3x-2y=5
eliminate y
4x=8
x=2
Substitute 4 x in equation 1
2+2y=3
y=1/2
Answer:
30
5 X 3 ÷ 8 + 3 X 2/5
= 15/11 X 2/5
(Take LCM of 5 and 11. LCM - 55)
15 X 5. 75
_____ =. ___
11 X 5. 55
2 X 11. 22
_____ =. ___
5 X 11 55
75 X 25. 1650
______ = ______
55. 55
= 30
