Answer:
15
Step-by-step explanation:
3(2+3)=
3(2) + 3(3)=
6 + 9=
6 + 9 = 15
Problem 7
Time is always an independent variable because time marches on doing its own thing without depending on external forces, or other people/things. Instead, other variables depend on time. In this case, the distance d depends on the independent variable t for time.
If the time goes up by 1 hour, then the distance variable goes up by 3 miles. In short, that tells us his speed is 3 mph.
Answer: Choice A) independent = time; dependent = distance

Problem 8
Everywhere you see an x, replace it with 9. Then use PEMDAS to simplify
f(x) = 5x - 9
f(9) = 5(9) - 9 ... x replaced with 9
f(9) = 45 - 9
f(9) = 36
Answer: 36
Answer:
c. mean: 9/20, median: 2/5, mode: 3/4
Step-by-step explanation:
3/4
,
2/5
,
1/10
,
3/4
,
1/4
It is best to order this list from low to high
low end, 1/10, 1/4, 2/5, 3/4, 3/4
middle is 2/5
mode = 3/4 the most repeated
mean: [2/20 + 5/20 + 8/20 + 15/20 + 15/20] * (1/5)= 45/20 *(1/5)
Answer:
5341
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
Add 2x-15 to both sides to get 2x=-12 or x = -6.
