Answer:
Rate of the Eastbound train is 93 mph.
Step-by-step explanation:
Let the speed of the Eastbound train = x miles per hour
And the speed of the West bound train = y mph
Eastbound train travels 14 mph slower than the westbound train,
So the equation will be,
y - x = 14 ----------(1)
If these trains are 400 miles apart after 2 hours,
Distance traveled by the Eastbound train = Speed × Time
= 2x miles
Distance traveled by the Westbound train = 2y miles
Trains are 400 miles apart after 2 hours,
So the equation will be,
2y + 2x = 400
x + y = 200 ----------(2)
By adding equation (1) and equation (2)
(y - x) + (x + y) = 14 + 200
2y = 214
y = 107 mph
From equation (1)
107 - x = 14
x = 107 - 14
x = 93 mph
Therefore, rate of the Eastbound train is 93 mph.
27 + 9x = 12x - 6
(Provide steps)
Answer:
Let's solve your equation step-by-step.
27+9x=12x−6
Step 1: Simplify both sides of the equation.
27+9x=12x−6
27+9x=12x+−6
9x+27=12x−6
Step 2: Subtract 12x from both sides.
9x+27−12x=12x−6−12x
−3x+27=−6
Step 3: Subtract 27 from both sides.
−3x+27−27=−6−27
−3x=−33
Step 4: Divide both sides by -3.
−3x
−3
=
−33

A TV that usually sells for $185.63 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?
Answer: A TV that usually sells for $185.63 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?
178.18 x 0.25 = 44.55
178.18 - 44.55 = 133.63 = sales price
133.63 x 0.05 = 6.68
133.63 + 6.68 = 140.31 = total price
Step-by-step explanation: That's how I solved it...

Answer:
6.75
Step-by-step explanation:
We are given that function
[tex]f(x)=\frac{9x-18}{4}[/tex]
5 is an element in the domain of f(x)
i.e
x=5
We have to find the corresponding element of 5 in the range of f(x).
Substitute x=5 in the given function
[tex]f(5)=\frac{9\times 5-18}{4}[/tex]
[tex]f(5)=6.75[/tex]
Hence, the corresponding element of 5 is 6.75 in the range.

6/7 times 3/4 = x
IN SIMPLEST FORM
Answer:
I believe 6/7 times 3/4 in the simplest form is 9/14 because you aren't able to put anything in both of those numbers
Step-by-step explanation:
The value of x in the equation (6/7) × (3/4) = x is 9/14.
To find the value of x in the equation (6/7) × (3/4) = x.
We can simply multiply the two fractions together.
Multiplying the numerators and denominators gives us:
(6 × 3) / (7 × 4)
= 18/28
The fraction 18/28 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
(18/2) / (28/2)
= 9/14
