Answer: hi, i can’t see the photo
Step-by-step explanation:
4m - 7n = 10
2m + 2n = 4 - multiply everything by -1.
4m - 7n = 10
-2m - 2n = -4 Add the 2 equations
(4m - 7n = 10)
+(-2m - 2n = -4)
-------------------------
2m - 9 n = 6.
The value of 2m - 9n would be 6.
Answer:
As per given Information
Side of square = 1 Km
we have to find the length of diagonal of square .
For finding the length of diagonal of square we will use formale
- Length of Diagonal = Side√2
Putting the value we get
↠ Length of Diagonal = 1√2 Km
So, the length of diagonal of square is 1√2 Km
Answer:
600 miles
Step-by-step explanation:
Since the scale is given as 1 inch = 50 miles
Then to get the distance when given 12 inches in a map we do cross multiplication as follows
1 inch = 50 miles
12 inch=x miles
By cross multiplication
1 inch*x miles=50 miles *12 inches
Making x the subject of formula then
X=50*12/1=600 miles
Therefore, the actual distance is 600 miles
