1. -6
2. 4
2. -1
The positive numbers will out rule the negative number. It's sort of like placing blocks over another set of blocks. :)
Answer:
90°
Step-by-step explanation:
5x+20=9x
20=4x
5=x
<DEG=5x+20+9x=5(5)+20+9(5)=25+20+45=90
Multiply
ignoring the square root sign for a moment to get
. Simplify
to get 20. so, your answer is B.
2/9 = 14/n
n = 14/2 * 9
n = 7 * 9
n = 63
In short, Your Answer would be 63
Hope this helps!
If the third term of the aritmetic sequence is 126 and sixty fourth term is 3725 then the first term is 8.
Given the third term of the aritmetic sequence is 126 and sixty fourth term is 3725.
We are required to find the first term of the arithmetic sequence.
Arithmetic sequence is a series in which all the terms have equal difference.
Nth term of an AP=a+(n-1)d
=a+(3-1)d
126=a+2d--------1
=a+(64-1)d
3725=a+63d------2
Subtract second equation from first equation.
a+2d-a-63d=126-3725
-61d=-3599
d=59
Put the value of d in 1 to get the value of a.
a+2d=126
a+2*59=126
a+118=126
a=126-118
a=8
=a+(1-1)d
=8+0*59
=8
Hence if the third term of the arithmetic sequence is 126 and sixty fourth term is 3725 then the first term is 8.
