Answer:
2. d) (x-1)²+(y+5)²=128
3.c) (x-3)²+(y+2)²=841
Step-by-step explanation:
Cost of the admission tickets: 11.75x
Cost of the box lunch: 5x
Expressions to find the total cost = (1) ....... 11.75x + 5x
That is equivalent to: (2) .......... (11.75 + 5)x = 16.75x.
Now calculate the cost for x = 5 using both expressions:
1) 11.75(5) + 5(5) = 58.75 + 25 = 83.75
2) 16.75(5) = 83.75
Of course you got the same result with both expressions.
Answer:
I think it is 3/2
Step-by-step explanation:
1 1/4 ÷ 5/6
5/4 × 6/5 = 30/20= 3/2
Well hello again :3. This is also quite simple. The diameter of a circle is 2 times the radius. So we can refit this into the equation and say that our new formula using diameter is

. Now we can say that 10/2 is 5 and

is 25. Therefore your answer is

or 78.54.
An octagon has 8 sides. Each side is 2a + 1 units.
8(2a + 1)
= 16a + 8
