The value of y will be y = 78 - 12 x.
An expression , 13 = 1/6y + 2x is given.
We have to solve the expression to find out the value of y.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
As per the question ;
The expression given is ;
13 = 1/6y + 2x
Let's solve it to get the value of y ;
So ,
13 = 1/6y + 2x
or
1/6y = 13 - 2x
multiplying both RHS and LHS by 6 , we get ;
y = 78 - 12 x
Thus , the value of y will be y = 78 - 12 x.

The coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° counterclockwise include the following:
U' = (1, 1).
V' = (-4, 0).
W' = (-1, 4).
In Mathematics and Geometry, the rotation of a point 90° about the center (origin) in a counterclockwise (anticlockwise) direction would produce a point that has these coordinates (-y, x).
By applying a rotation of 90° counterclockwise to the vertices of triangle UVW, the coordinates of the vertices of the image are as follows:
(x, y) → (-y, x)
Ordered pair U = (-1, 1) → Ordered pair U' = (1, -(-1)) = (1, 1).
Ordered pair V = (0, -4) → Ordered pair V' = (-4, -(0)) = (-4, 0).
Ordered pair W = (-4, -1) → Ordered pair W' = (-1, -(-4)) = (-1, 4).

The unit rate in feet per second of 240 yards per 1-hour will is 0.2 feet per second.
To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
Another example could be kilo gram to gram.
Given that,
Speed = 240 yards/hour
Since,
1 yard = 3 feet ⇒ 240 yards = 720 feet
And
1 hour = 60 minutes ⇒ 1 hour = 3600 seconds
So,
240 yards/hour = 720/3600 feet/second
⇒ 0.2 feet / second.
Hence "The unit rate in feet per second of 240 yards per 1-hour will is 0.2 feet per second".

Answer:
This is a numerical expression or D.
Step-by-step explanation:
It is not algebraic because it doesn't include unknown variables such as x or y
and it is not a numerical equation because equations have equal signs in them such as 5 + 6 = 11
Answer:
it is a numerical expression
Step-by-step explanation:
it is not an algebraic equation because there are no variables say, p or q or any other variables attached or unattached to its coefficients. And no equal sign attached to it.
it is not an algebraic expression.
it is not a numerical equation because it has no equal sign neither is it equating itself to another.
finally, it is a numerical expression because it only consists of numbers and has no equal sign. Or it is not equating to any other solution.
