Answer:
The number of letters in the one street be 220 .
Step-by-step explanation:
As given
A postman has to deliver 450 letters .
The number of letters delivered in one street is twice the number delivered in other .
Let us assume that the number of letters delivered in second street be x.
Let us assume that the number of letters delivered in first street = 2x
As given
If he is left with 120 letters .
Thus
The number of letter delivered in one and other street = 450 - 120
= 330
Than the equation becomes
x + 2x = 330
3x = 330
x = 110
The number of letters in the one street = 2 × 110
= 220
Therefore the number of letters delivered in first street be 220.

Answer:
(-2,-3)
Step-by-step explanation:
Since there is a point P including coordinates (-1,5) and it is shown on a horizontal line i.e y =1
Now we have to compute the new coordinates of P
If a point is mirrored along a horizontal line, only vertical distance varies, however the horizontal distance is still the same, i.e. from y axis or x coordinate.
Therefore new x coordinate = -1
As P has 4 distance from the line y =1
Therefore P' will also contains a distance of 4 on the other side of y = 1
i.e. y coordinates could be
= 1 - 4
= -3
hence, the new coordinate is (-2,-3)
It is obvious that Triangle BCD is congruent to Triangle EFG. EFG is twice the size of BCD.
Put the lengths into the pythagorean theorem equation. (the longest side is the hypotenuse)
So for Triangle BCD
3^2+b^2=5^2
(3×3)+b^2=(5×5)
9+b^2=25
So what plus 9 equals 25?
16
the square root of 16 is 4 so 4^2=16
9+16=25
Now since we know that Triangle EFG is twice the size of BCD remake the equation but the numbers will be:
6^2+8^2=10^2
Now check
(6×6)+(8×8)=(10×10)
36+64=100
100=100
So for Triangle EFG X=8
