Answer:
= 6n - 2
Step-by-step explanation:
Because you can use the formula = a1 + d (n - 1) to identify the arithmetic sequence :)
Answer:
Step-by-step explanation:
4x + y = - 1 -------------(I)
-5x - 2y = -4 -----------(II)
Multiply the equation (I) by 2 and then add the equations.
(I)*2 8x + 2y = -2
(II) <u>-5x - 2y = -4</u> {Now add and y will be eliminated}
3x = -6
x = -6/3
x = -2
Substitute x = -2 in equation (I)
4*(-2) + y = -1
-8 + y = -1
y = - 1 + 8
y = 7
Answer:
The answer is 72:127
Step-by-step explanation:
It's 72:127 because the original ratio is 288 which can be simplified by dividing each side by 4 to get 72 completed passes and 127 attempts.
Answer:
If the sign before the no. is same then they will get added and the resultant will have the same sign too.
Since before 28 and 12 , both of them have the negative sign , they will get added and the sign of their resultant will be negative too.
So , -28-12 = -40
Now, if the sign before the no.s are different then there will be subtraction, and the sign before the highest no. will be the sign of the resultant.
So,( -28)+38+(-12)
= -28+38-12
= -40+38
= -2
We know that 40> 38
sign before 40 is negative, therefore, their resultant i.e 2 will also get the negative sign

the sum of all interior angles in a polygon is
180( n - 2), where n = "number of sides".
now, this is an 11-gon, so the sum is
180( 11 - 2)
180(9)
1620.
