Two trains traveling the same speed leave the city. The southbound train reaches its destination in 45 minutes. The eastbound train reaches its destination in one hour. how fast were the trains traveling if their destinations are 88 miles apart.
Answer:
70.4 mphStep-by-step explanation:
Let the speed be x mph
The distances are
45/60x= 3/4x and xThe line connecting the two destinations is the hypotenuse of the right triangle with legs of 3/4x and x, which is 88 miles
Then we can put it as expression and solve for x:
(3/4x)² + x² = 88²9/16x² + x² = 88²25/16x² = 88²25x² = 4²*88²(5x)² = 352²5x = 352x = 352/5x = 70.4 mphWhich of the following is the best estimate for the total change in distance from the group of students' original position at the surface? Round to the nearest ten.

On a map, the distance between two cities is 26 cm. If the map scale is 2 cm: 11 mi., what is the actual distance between the two cities?
Answer:
143 miles
Step-by-step explanation:
To get the answer, you should first, divide 25 cm by 2 cm = 13 cm so it will be easier for you to multiply. Then you should multiply = 13 by 11 = 143 miles
What is X?
x + 1 + 4x = 11 + 12x - 3
5x+1=11+12x-3
5x+1=8+12x
5x+1-12x=8
-+1=8
-7x=7
x=\frac{7}{-7}
answer:
x=-1
The value of x would be equal to -1.
An equation is defined as an expression that shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.
We are given the equation as;
x + 1 + 4x = 11 + 12x - 3
Now solve for x;
x + 1 + 4x = 11 + 12x - 3
5x+1=11+12x-3
5x+1=8+12x
5x+1-12x=8
-7x = 8 - 1
-7x=7
x=-1
The solution will be -1.

A hiker is 3.5 miles from her campsite when she begins to walk back to it. She hikes back toward the campsite at a constant rate of 2.1 miles per hour.
Which equation models the distance of the hiker from her campsite? (Let m represent her distance, in miles from the campsite and h represent the number of hours since she begin walking back.)
O m= 3.5+ 2.1h
Om= 3.5h - 2.1
O m = 3.5h + 2.1
m = 3.5 - 2.1h

Find the slope of each line (each block is one unit):
Answer:
m = -2/3
Step-by-step explanation:
m = slope
[tex] m = \frac{y2 - y1}{x2 - x1} [/tex]
m = -3 -1/ 3 - (-3)
m= -4/ 6
m= -2/3
