How do you solve t=1/8sv and solve for v?
Kruka [31]

Answer:

v = (8t)/s

Step-by-step explanation:

Divide both sides by 1/8, so multiply both sides by 8.

8t = sv

Divide both sides by s.

(8t)/s = v

Switch sides.

v = (8t)/s

Help I'm not comfortable with negative numbers
Gemiola [76]
B) < because the more negative or the farther away from zero a number is the smaller it is 
c) = because if you subtract a negative number you are basically adding
d) = because anytime you multiply a negative by positive your answer will always be negative

a) -11 because -8+3=-5 and -5-6=-11
b) 11 because when you multiply a negative number by another negative your answer will always be positive so -3x-2=6 and 6+5=11
c) -4 because a negative number divided by a positive is always negative 
d)42 because a negative number subtracted by a positive number makes a number more negative (btw always solve things in parenthesis first) so -4-3=-7 and again a negative multiplied by another negative is always positive so -7x-6=42
