Step-by-step explanation:
X^2-y^2=55
this means that
(x+y)(x-y)=55
we know that x-y=11 so we can write
(x+y)(11)=55
x+y=55/11 we divide by 11 and we obtain
x+y=5
x-y=11 this means
x=y+11 we replace in the other equation (x+y=5)
y+11+y=5
2y=5-11
2y=-6
y=-3
and you find out that also
x=8
Answer: The answer is B, good luck

The answer is Ms Hernandez can bring up to 6 people to the zoo.
x - <span> the number of people that she can bring to the zoo
</span><span>The parking will cost $7: a = 7
</span><span>Admission tickets will cost $15.50 per person: b = 15.50x
She can spend on parking and admission tickets </span><span>$100:
a + b </span>≤<span> 100
a = 7
b = 15.50x
7 + 15.50x </span>≤<span> 100
15.50x </span>≤<span> 100 - 7
15.50x </span>≤<span> 93
x </span>≤<span> 93 / 15.50
x </span>≤ 6
