Answer:
2080
Step-by-step explanation:
The solution to these equations might best be found using Cramer's Rule. It tells you ...
x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400
This is years after 1990, so the year the incomes become the same is predicted to be ...
1990 +90.4 = 2080.4
The median incomes will be the same in the year 2080.
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3
4 1/5 - 2/3
Turn 4 1/5 into an improper fraction.
5x4+1= 21/5
21/5 - 2/3
Multiply 5 and 21 by 3 and 3 and 2 by 5 to get the same denominator.
63/15-10/15=53/10
Turn the improper fraction into a mixed number by dividing the 53 and 10.
Answer: 5 3/10 or five and three tenths
