A diesel train left Abuja and traveled west.Two hours later a freight train left traveling 15 mph faster in an effort to catch up to it. After six hours the freight train finally caught up. Find the diesel train's average speed. (Need to have chart and explanation)
Step-by-step explanation:
let the speed of diesel train = x
the equation would be:
(2+6)x = 6(x+15)
8x = 6x+90
8x-6x = 90
2x = 90
x = 90/2
x = 45
Therefore, the speed of diesel train =
45 mph

Work out m and c for the line: 3 y + 6 x = − 3
Answer:
m is -2 and c is -1
Step-by-step explanation:
• Let's first phrase out the general equation of a line
[tex]{ \rm{y = mx + c}}[/tex]
m is the slopec is the y-intercept[ remember that a general line equation must be in slope - intercept form as shown above ]
• from our question, we are given the equation;
[tex]{ \rm{3y + 6x = - 3}}[/tex]
• let's make y the subject in order to make the equation in slope - intercept format.
→ remember to apply "subject making knowledge"
[tex]{ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}[/tex]
• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c
[tex]{ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}[/tex]
Pls help me with this
Step-by-step explanation:
let's just write the equations on top of each other as in a large subtraction, then transform one of them so that at least one term is the range in both equations, and then do the subtraction.
a)
I automatically write rational numbers as the total fractions (14 1/4 = 57/4, 3 3/4 = 15/4)
15x - 7y = 57/4
- 5x - y = 15/4
15x - 7y = 57/4
- 15x - 3y = 45/4
-------------------------
0 -4y = 12/4
y = -(12/4)/4 = -12/16 = -3/4
then we use that in the simpler second equation
5x - -3/4 = 15/4
5x + 3/4 = 15/4
5x = 12/4
x = (12/4)/5 = 12/20 = 3/5
b)
we don't need to transform any equation, as the x terms are already equal.
3x - 4y = 2
- 3x - 7y = -1
-------------------
0 3y = 3
y = 3/3 = 1
using this in e.g. the first equation
3x - 4×1 = 2
3x - 4 = 2
3x = 6
x = 6/3 = 2
which inequality is true when the value of w is 13 w-<5 -w-3>-5 -w-3>5 w->5
w > -5 shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true
We need to get the equation that is true for w to be 13. This means that the required inequality expression should be w must be a positive integer.
For the Expression -w - 3 > -5
-w > -5 + 3
-w > -2
w < 2
Since w is less than 2, hence the inequality is wrong
For the inequality
-w - 3 > 5
-w > 5 + 8
-w > 13
w < -13
Since w < -13, hence the inequality is wrong
For the inequality w > -5
It shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

Kadeem wants to ride his bicycle 52 miles this week. He has already ridden 16 miles. If he rides for 5 more days, write and solve an equation which can be used to determine xx, the average number of miles he would have to ride each day to meet his goal.
How to solve this for an equation.
The average number of miles that would be ridden to meet his goal is 7.2 miles.
Total distance = 52 miles
Distance ridden = 16 miles
Number of days left = 5 days
Let the number of miles that'll be ridden for each day be represented by x.
Therefore, the equation to solve the question will be:
5(x) + 16 = 52
5x + 16 = 52
5x = 52 - 16
5x = 36
x = 36/5
x = 7.2
Therefore, he'll have to ride 7.2 miles per day.

|x-1|+2<4 solving for x
Answer:
x < 3 and x > -1
Step-by-step explanation:
Step 1: Subtract 2 from both sides.
[tex]|x-1| + 2 - 2 < 4 - 2[/tex] [tex]|x-1|<2[/tex]Step 2: Solve absolute value.
We know x - 1 < 2 and x - 1 > -2.Condition 1:
[tex]x - 1 < 2[/tex] [tex]x - 1 + 1 < 2 + 1[/tex] (Add 1 to both sides)[tex]x < 3[/tex]Condition 2:
[tex]x - 1 > -2[/tex] [tex]x - 1 + 1 > -2 + 1[/tex] (Add 1 to both sides)[tex]x>-1[/tex]Therefore, the answer is x < 3 and x > -1.
The midpoint of AB is M(-2, 1). If the coordinates of A are (-3,-5),
what are the coordinates of B?
Answer:
B= (-1, 7)
Step-by-step explanation:
Midpoint formula is X1 plus X2, then divided by 2. So, because the midpoint is given you work backwards. So for the x value do (-3 + x) divided by 2 equals -2 and solve for x and you do the same thing for the Y value

In a toy factory, 36 machines are required to produce a certain number of toys in 54 days. How many
machines does it take to produce the same number of toys in 81 days?
Answer:
24 machines
Step-by-step explanation:
36*54= x*81
x=36*2/3
x=24
Answer:
24
Step-by-step explanation:
We can set up a simple equation and solve for x to get our answer
36 machines for 54 days = x machines for 81 days
we know that they will produce the same amount of toys as the end result, so we can set both equations equal to each other and solve for x
so,
[tex]36*54=81x\\\\\frac{(36*54) }{81} =x\\\\\frac{1944}{81}=24 \\\\x=24[/tex]
first, divide both sides by 81
then multiply 36 with 54 and divide by 81
and we get x=24
So it'll take 24 machines to produce the same number of toys in 81 days
