Answer:
Below in bold.
Step-by-step explanation:
x^2 - y^2 = 11
2x^2 + y^2 = 97
From the first equation:
y^2 = x^2 - 11
Substituting in the second equation:
2x^2 + x^2 - 11 = 97
3x^2 = 108
x^2 = 36
x = 6, -6.
Substituting for x in the first equation:
(6)^2 - y^2 = 11
y^2 = 36 - 11 = 25
y = 5, -5.

Answer:
1+1=2
Step-by-step explanation:
In 2000, 7689 weekly papers = 94% of number of weekly papers in 1960
Let weekly papers in 1960 be x.
7689 = 94% of x
7689 = (94/100)*x
7689 * 100/94 = x
8179.787 ≈ x
x ≈ 8179.787
Number of weekly newspapers in 1960 rounded to the nearest whole number = 8180
