Answer: 6km

Explanation:
By using the formula d=v x t
And knowing:
V=9km/h
t= 40 min = 2/3hr
We get an equation:
d= 9 x 2/3 = 6km

Answer:

6 km

Step-by-step explanation:

40 min = 40/60 h = 4/6 h = 2/3 h

1 h ................. 9 km

2/3 h ..............x km

x = 2/3×9km = 18/3 km = 6 km

Hi :) I need help with the question in the screenshot if anybody knows it can you plz help I will give you brainliest, thanks an
amm1812

This question is difficult to give a definite answer to because it's an approximation, but I estimate the solutions to be around x = 2.6 and x = -2.6.

When they ask for solutions of the graphed function they are asking for an approximation of where the graph intercepts the x-axis, and we can see it kind of intercepts in the middle of 2 and 3, except slightly closer to 3, which is why I estimated 2.6.

The graph also appears to be symmetrical, which means the solutions will be the same except one would be negative and one would be positive, which means the second solution would be -2.6.

I hope this helps! Let me know if you have any questions :)

Solve 2(x-2) = 3(x+2)-8
IgorC [24]

Answer:

x = -2

Step-by-step explanation:

2(x-2) = 3(x+2)-8

Multiply the 2 and 3 out to the numbers in the parentheses. Don't multiply the 3 out to the -8 because it is outside of the parentheses.

2x-4 = 3x+6-8

Combine the 6 and -8

2x-4 = 3x-2

Subtract 2x from both sides

-4 = x-2

Add 2 to both sides

-2=x
