169 miles * 5280 ft/ mile = 892320 ft
3 hours * 60 minutes/1 hr = 180 minutes
3 hrs 30 minutes = 180 minutes + 30 minutes = 210 minutes
169 miles/ 3 hrs 30 minutes = 892320 ft/ 210 minutes = 4249.1 ft/ minutes
Answer:
2x - y - 7 = 0
Step-by-step explanation:
Since the slope of parallel line are same.
So, we can easily use formula,
y - y₁ = m ( x ₋ x₁)
where, (x₁, y₁) = (8, 9)
and m is a slope of line passing through (x₁, y₁).
and since the slope of parallel lines are same, so here we use slope of parallel line for calculation.
and, Slope = m = 
here, (xₐ, yₐ) = (2, 7)
and, 
⇒ m = 
⇒ m = 2
Putting all values above formula. We get,
y - 9 = 2 ( x ₋ 8)
⇒ y - 9 = 2x - 16
⇒ 2x - y - 7 = 0
which is required equation.

Answer:
d= -2
Step-by-step explanation:
7 + 4d + 5d = 7d + 3
Combine like terms
7+9d = 7d+3
Subtract 7d from each side
7+9d-7d = 7d-7d+3
2d +7 = 3
Subtract 7 from each side
2d+7-7 = 3-7
2d = -4
Divide each side by 2
2d/2 = -4/2
d = -2
Answer:
The sum is

Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:

We group similar try to get:

We now combine the similar terms to obtain:

Therefore the sum is
