Answer:
-2
Step-by-step explanation: All you have to do is insert the s and t value they gave you into the equation.
2s + 4t = ?
2(3) + 4(-2) = ?
6 + (-8) = ?
= -2
Isolate the variable by dividing each side by factors that don't contain the variable.
The Answer is B
2d/t^2
Answer:
Sam's time was 1 hour and 6.66 minutes (or 1 and 1/9 hours)
Liam's time was was 1 hour
So in conclusion, Liam was faster
Step-by-step explanation:
We got Sam's time by 1/1 because Sam was walking 1 mph and the length to reach the top of the hill is 1 mile. So it would take Sam 1 hour to walk 1 mile. Walking down the hill Sam's speed was 9 mph. So the equation would be 1/9. So you would get 1/9. 1/9 of 60 is 6.66 repeating.
For Liam it is pretty simple. Since he is going up the hill at 2 mph and the length of the bottom of the hill to the top is 1 mile, it would be 30 minutes. Repeat this for the top to the bottom and in total it would be 1 hour.
Hope this helps
Respuesta:
(segundo + 3) (segundo + 2) = 0
Explicación paso a paso:
Dada la expresión cuadrática b² + 5b + 6, debemos factorizarla;
b² + 5b + 6 = 0
b² + 2b + 3b + 6 = 0
b (segundo + 2) +3 (segundo + 2) = 0
(segundo + 3) (segundo + 2) = 0
Por tanto, el factor requerido es (b + 3) (b + 2) = 0
Answer:
x = -7
Step-by-step explanation:
2x+2-x+5=0
x+2+5=0
x+7=0
x = -7
So the answer is -7
