Answer:
The answer would be D, 37/2 divided by 17/4
Explanation:
I did the test.
Boxes = 3_2/5
15 = total number of bags of favors
Each bag has 3 items inside
3 × 15 = 45
Total number of items = number of boxes plus (15 × 3).
So, choice A is the answer.
Answer:
Step-by-step explanation:
eq. of circle is x²+y²+2gx+2fy+c=0
center=(-g,-k)
given eq. is x²+y²+4x-8y+11=0
comparing
2gx=4x
g=2
2fy=-8y
f=-4
center=(-2,4)

Here we need to set a system of two linear equations in two variables. So:
- <em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>
Let
be those digits, then:

- <em>If 9 is added to a number then both the digits become equal. find the number:</em>
<em />
<em />
<em />
<em />
But from eq 1:

Substituting y into the expression 1:

The x-value will be found by hit and trial, so:

We have to reject this solution because digits are different.

We have to reject this solution because digits are different.

<em>Then this is a two digit number formed by two equal digits. </em>
Finally, the number is:
