Remark
The trick here is to realize that between them they will cover 600 miles
Train one
r = 90 mph
t = ?? [same for both trains]
d = d1
Train Two
r = 75 miles / hour
t = ?? [same for both trains]
d = d2
Equation.
basically d = r*t
d_train1 + d_train2 = total_distance
90*t + 75*t = 600
Combine and solve
165t = 600 Divide by 165
t = 600/165
t = 3.64 hours <<<<<< Answer
Answer:
The expression consists of two factors, and each factor contains three terms.
Step-by-step explanation:
<u>Factors</u> are numbers that <u>multiply</u>. The two brackets are written stuck to each other without any symbol between them, which means they are multiplying.
(a+b+c) is the first factor.
(d+e+f) is the second factor
<u>Terms</u> are numbers that <u>separated by addition or subtraction</u>.
Inside the first bracket, the terms are "a", "b", and "c".
Inside the second bracket, the terms are "d"", "e", and "f".
We see that the angle measures are the same, but the side lengths aren't, so these shapes qualify as similar. Since it's similar, they are also the same shape.
Choices C and D

Answer:
the eq of line is y= -0.25x-6
Both slopes are going to be the same, as parallel lines have the same slopes but different y-intercepts. To find the slope of this line (if you haven’t already), you need to isolate y.
4x - 5y= -1
-5y= -4x - 1 (or -1 - 4x)
-y= (-4/-5)x - 1/5
Canceling out the negatives,
y= (4/5)x + 1/5.
Therefore, the slope of both the listed line and any line parallel to it is 4/5.
