689 = 700
3.10 = 3
700 x 3 = 2,100
the answer is 2,100
Hope this helps!
Answer:
Step-by-step explanation:
3x-2y≤ -4
put x=1,y=5
3×1-2×5 ≤ -4
3-10≤ -4
-7 ≤ -4
which is true.
so (1,5) is a solution.
Answer:
<h2>32 copies</h2>
Step-by-step explanation:
First convert 3 minutes and 15 seconds into minutes by converting 15 sec to min and add it to 3min
60 sec = 1min
15 sec = 15 / 60 × 1 min
= 0.25min
Add it to 3min
3min + 0.25min = 3.25 min
<u>We use ratio and proportion</u>
3.25min = 104 copies
1 min = 104× 1/ 3.25
= 104 / 3.25
= 32
The final answer is 32 copies

The perimeter of quadrilateral B is 12.
<u><em>Explanation</em></u>
Quadrilateral A has side lengths as 6, 9, 9 and 12. In quadrilateral B, length of the shortest side is 2.
As quadrilateral B is a scaled copy of quadrilateral A, so <u>the scale factor</u> will be...
<em>(Shortest side of B / Shortest side of A)</em> 
Now the remaining side lengths for quadrilateral B will be.....
and 
⇒ 3 , 3 and 4
Thus, the perimeter of quadrilateral B is 
Complete Question:
Let x and y be positive integers and x be greater than y.
11x/11y = ?
Answer:
11x/11y = x/y
Step-by-step explanation:
Given
x > y
Required
11x/11y
From the question, we understand that x is greater than y (i.e. x > y)
Also, we'll assume that y ≠ 0, in other not to result in an undefined result.
So,
11x/11y
Divide the numerator and denominator by 11
(11x ÷ 11)/(11y ÷ 11)
The result of the division is:
(x)/(y)
x/y
Hence,
11x/11y = x/y for x > y and y ≠ 0
