To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.

Width = 
Step-by-step explanation:
The scale of the toy train is 
So, the dimensions of the toy train is times the actual dimensions of the train.
The dimensions of actual train is 
times the toy train's dimensions.
Length

The width of the railroad car on the long island railroad is 18 inches.
In the parallelogram PQRS
<h3>What is defined as the parallelogram?</h3>
- A parallelogram is a type of quadrilateral created by parallel lines.
- A parallelogram's angle between adjacent sides can vary, however the opposite sides must be parallel in order to be a parallelogram.
- A parallelogram is formed when the opposite sides of a quadrilateral are parallel as well as congruent.
For the given question;
In the parallelogram PQRS,
QR = PS = 5 (opposite side of parallelogram are parallel and equal).
Sum of all angles is 360.
∠Q = ∠S (opposite angles of parallelogram are equal)
∠P + ∠Q + ∠R + ∠S = 360
2∠P + 2∠Q = 360
2∠Q = 360 - 2∠P
2∠Q = 210
∠Q = 105
Thus, the angle Q is found as 105 degrees.

Answer:
a = 12
Step-by-step explanation:
Formula for calculating the slope of a line is expressed as;
m = ∆y/∆x
m = y2-y1/x2-x1
Given
m = 1/2
x1 = a
y1 = 14
x2 = 8
y2 = a
Required.
Value of a
Substitute the given parameters into the formula
1/2 = a-14/8-a
Cross multiply
1(8-a) = 2(a-14)
8-a = 2a-28
Collect like terms
-a-2a = -28-8
-3a = -36
a = -36/-3
a = 12
Hence the value of a is 12
