Answer:
B) 72
Step-by-step explanation:
The n-th term of an arithmetic sequence An = a1 + (n - 1) d
Given :
a28 = 423/4 and d = 5/4
So
a28 = a1 + (28 - 1)5/4
Now plug in a28 = 423/4
423/4 = a1 + 27(5/4)
a1 = 423/4 - 27(5/4)
= 423/4 - 135/4
a1 = (423-135)/4
a1 = 288/4
a1 = 72
Thank you.
Answer:
what you have written that
175 divide by 25 should be 7
then using 80 divide by 40 is 2
7+2=9
then 2 times 40, and 7 times 25, the result is 285
285 divide by 9 get 31.6666......... or 31.7
<span>18x+9xy is correct all Roots are to x=0 and y=-2
(9x⋅2)+(9x⋅y) is correct </span>Roots are to x=0 and y=-2
Hello,
-(-5) is also known as just a plain positive 5. When two negatives are multiplied together, they make the number positive. So, the location of -(-5) on a number line would be on the number 5. I hope this helps!
