Average speed is the distance traveled by an object in total and divided by the amount of time an object covers the distance. The formula is -
Average speed = total distance traveled / total time taken
= 68km+64km / 2 hrs.+3hrs.
= 132km / 5hrs.
= 26.4km/hr.
Therefore, the train's average speed is 26.4km/hr.
Plug in e for 3.
10(3+7)
Use the distributive property. a(b+c)= ab+ac
10*3= 30, 10*7=70
30+70=100
The expression equals 100.

Answer
x=-12
Explanation
Move the terms
-17-2x=7
Add the numbers
-2x=24
Divide both sides of the equation by -2
x=-12

Answer:
x = 12.35
Step-by-step explanation:
Tan(39) = 10/x
Tan(39) * x = 10
x = 10 / Tan(39)
<u>x = 12.35</u>
Hope this helps!
Answer:
B
Step-by-step explanation:
p(x) = r(x) * s(x)
= (x + 5) *(-7) {Use distributive property}
= x * -7 + 5 * -7
= - 7x - 35
