Answer:
<u>The Eastbound train speed is 76.5 miles per hour and the Westbound train speed is 79.5 miles per hour.</u>
Step-by-step explanation:
1. Let's review all the information provided for solving this question:
Eastbound train speed = x
Westbound train speed = x + 3 miles per hour (The speed of the westbound train is 3mph greater than the speed of the eastbound train)
Duration of trip = 3 hours
Distance between trains after 3 hours = 468 miles
2. Let's find the speed of each train, using the following equation:
3x + 3(x + 3) = 468
3x + 3x + 9 = 468
6x + 9 = 468
6x = 468 - 9 (Subtracting 9 at both sides)
6x = 459
x = 459/6 (Dividing by 6 at both sides)
x = 76.5 miles per hour
<u>The Eastbound train speed is 76.5 miles per hour and the Westbound train speed is 79.5 miles per hour.</u>
3. Proof that x = 76.5 is correct
3x + 3(x + 3) = 468
3 (76.5) + 3 (76.5 + 3) = 468
229.5 + 238.5 = 468
<u>468 = 468</u>
<u>The value of x = 76. 5 is correct. And now we know that the Eastbound train has traveled 229.5 miles since the departure from Cleveland and the Westbound train 238.5 miles.</u>
Answer:
11 c; 12 c; 13 b
Step-by-step explanation:
Question 11
Question 12
(a) Add up the total fluid ounces
(b) Convert fluid ounces to millilitres
Question 13
1 L =10 dL
y = mx + b
slope(m) = -4/5
(10,5)...x = 10 and y = 5
now sub into the formula and find b, the y int
5 = -4/5(10) + b
5 = -40/5 + b
5 = -8 + b
5 + 8 = b
13 = b
so ur perpendicular equation is : y = -4/5x + 13 <===
Hope this helps!
Answer:
If you are finding the Area in which you would need for the carpet would be A= 232 ft
Step-by-step explanation:
A = lw
l = 16
w = 14.5
16 x 14.5 = 232 feet
Answer:
Step-by-step explanation:
As the equation is given in the question as follows.
2.5(6x-4)=10+4(1.5+0.5x)
open the bracket
2.5 × 6x - 2.5 × 4 = 10 + 4 × 1.5 + 4 ×0.5x
15x - 10 = 10 + 6 + 2x
15x - 2x = 16 + 10
13x = 26
x = 2
