(1) Option B: –10
(2) Option A: –3
Solution:
(1) Given expression is 37 + n.
To evaluate the value of the expression when n = –47.
Substitute n = –47 in the given expression.
37 + n = 37 + (–47)
Since positive of a negative number is negative.
37 + n = 37 – 47
Subtract 37 from 47 and put the greater number sign for the answer.
37 + n = –10
Option B is the correct answer.
Hence 37 + n = –10.
(2) Given expression is p – q.
To find the the value of the expression when p = –37 and q = –34
p – q = (–37) – (–34)
Since negative of a negative number is positive.
p – q = (–37) + 34
Subtract 34 from 37 and put the greater number sign for the answer.
p – q = –3
Option A is the correct answer.
Hence p – q = –3.

Answer:
$561, yes!
Step-by-step explanation:
after 4 weeks, they will have 21*4=$84 per kid (4 kids). Therefore we need to multiply this by 4. 84*4=$336. You must remeber that they started with $225, so 225+336=$561, which is more than $512, so they can pay for the trip!
<em>Answer:</em>
<em>The solution is (5, −2)</em>
<em>Step-by-step explanation : </em>
<em>x + y = 3 => y = 3 - x</em>
<em> y = x - 7 } => </em>
<em>=> 3 - x = x - 7 => 3 + 7 = x + x => 2x = 10 => </em><em>x = 5</em>
<em />
<em>x + y = 3</em>
<em>5 + y = 3</em>
<em>y = 3 - 5</em>
<em>y = - 2</em>
