Answer:

Step-by-step explanation:

arithmetic sequence: aₙ = a₁ + (n-1)d

a₈ = (-5) + (8-1)d = 37

7d = 42

d = 6

a₃ = -5 + (3-1) x 6 = 7

A/-8+15greater than 23

Ilia_Sergeevich [38]

Answer: $a$

Step-by-step explanation:

$\frac{a}{-8}+15>23$

Subtract 15 from both sides.

$\frac{a}{-8}+15-15>23-15\\\frac{a}{-8} >8$

Multiply by -8 to isolate a.

NOTE: When you multiply or divide by negative numbers, the inequality sign flips.

$-8*\frac{a}{-8}>8*-8$

$a$

Which of integers is least -5+(-2),-5÷(-2),-5×(-2),-5

liberstina [14]

Answer:

-5+(-2)

Step-by-step explanation:

-5+(-2)= -5-2 = -7

-5/(-2) = 5/2 = 2.5

-5*(-2) = 5*2 = 10

-5 = -5

So, -5+(-2) is the least.
