5 - 7 = - 2 ;
- 2 - 7 = - 9 ;
-9 - 7 = -16 ;
"common difference" d is - 7 ;
The n-th term of an arithmetic sequence is of the form <span>an = a1 + (n – 1)d ;
</span>a50 = 5 + 49 × ( - 7 ) = 5 - 343 = - 338;
- 2(x + 7)
mutiply the bracket by -2
(-2)(x)= -2x
(-2)(7)= -14
Answer:
-2x-14
Given data:
The given biology percentage is B=40%.
The given chemistry percentage is C=24%.
The percenage of earth science as compare to physics is E=P+4%.
The expresion for the sum of all subjects is,
B+C+E+P=100%
40%+24%+E+P=100%
E+P=36%.............................(I)
Substitute given value in the above expression.
P+4%+P=36%
2P=32%
P=16%
The nummber of students assigned earth science is,
E=16%+4%
=20%
Thus, the percentage of the students assigned to the physics subject is 16%.
Answer:
2
(I think) ¯\_(ツ)_/¯
Step-by-step explanation:
cause 5 would be X and then that leaves 2 for Y
(5,2)
(X,Y)
Answer:
1lb 8 oz
Step-by-step explanation:
Take 3 lbs and separate it into 48oz + 4 oz = 52 oz.
Same with the 1 lb 12 oz. 16 oz + 12 oz = 28.
Subtract 28 from 52 = 24 oz = 1 lb 8 oz.
Hope this helps.
