Answer:
72 adults
22 children
Step-by-step explanation:
Let c = no. of children
a = no. of adults
Then 4c = total sales for the children and
7a = total sales for the adults
So, a + c = 94 and 7a + 4c = 592
<u> -4a - 4c = -376</u>
3a = 216
a = 72 adults
72 + c = 94
c = 22 children
The value of u is -144
<em><u>Solution:</u></em>
Given that,

We have to solve for "u"
From given,

Convert the division problem into multiplication, by changing the division sign to multiplication sign. Then invert the number to right of division sign
Thus we get,

Isolate for u

Thus the value of u is -144
Answer = V (2,1)
Because:
The equation of the circle is
(x+1)² + (y+3)² = 25
(2+1)² + (1+3)² = 25
3² + 4² = 25
9 + 16 = 25
25 = 25
1 is on “greater than”
2 is on “less then”
3 is on “between”
4 is on “between”
5 is on “between”
6 is on “less then”
7 is on “greater then”
