Find the 7th term of the arithmetic sequence 5x + 9, 8x + 5, 11x + 1,...

ohaa [14]

Answer:

Step-by-step explanation:

In arithmetic sequence: a₂ - a₁ = a₃ - a₂ {common difference}

$a_1=5x+9\\a_2=8x+5\\a_3=11x+1\\\\\\d=8x+5-(5x+9)=8x+5-5x-9=3x-4\\\\a_n=a_1+d(n-1)\\\\a_7=5x+9+(3x-4)\cdot6\\\\a_7=5x+9+18x-24\\\\a_7=33x-15$

a computer and printer a totoal cost $1132 the cost of the computer is three times the cost of the ptinter

zavuch27 [327]

Use a system of equations

C+P=1132
3P=C

Substitute C in first equation as
3P+P=1132
Simplify
4P=1132
Solve
P=1132/4
P=283

NOW SOLVE FOR C SUBSTITUTING P VALUE IN FIRST EQUATION

C+283=1132
C=1132-283
C=849

Printer = 283$
Computer = 849$
