Woahh thats a lot of points!! Thank you!!!!
11b+7=40
Subtract 7 from both sides.
11b+7−7=40−7
11b=33
Divide both sides by 11.
11b/11 = 33/11
b=3
The question tackles about arithmetic sequence.
Arithmetic sequence has the formula:
an<span> = a</span>1<span> + (n – 1)d.
</span>where
an = number at nth term
a1 = 1st term
n = number of terms
d = common difference.
an<span> = a</span>1<span> + (n – 1)d.
</span>a1 = -10
d = -2
n = 10
a2 = -10 + (2-1) -2
a2 = -12
if we continue until a10, the sequence will be
-10, -12, -14, -16, -18, -20, -22, -24, -26, -30
Answer: the answer is 56
Hope this Help
Step-by-step explanation:
100%= 25
X%= 14
100%=25(1)
X% = 14(2)
100%/x% = 25/14
X%/ 100% = 14/25
X=56%
