Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same. The given equation is equivalent to the expression one half and one half <em>x.</em>
Given information-
The expression given in the problem is,
<h3>Equivalent expression-</h3>
Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.
For given expression,
As the above function is the function of <em>x. </em>Thus it can be written as,
The number four is the product of number 2 and number 2. Thus,
Hence the given equation is equivalent to the expression one half and one half <em>x.</em>

Answer:
m = 57t, where the units of measurement of 57 are mph and that of t is hr.
Step-by-step explanation:
Use the given info to find the speed of the train, which is a unit rate:
95 miles 95 mi
------------------ = ------------- = 0.95 mile/min
1 hr 40 min 100 min
Better yet, use hours, not minutes.
95 miles 95 mi
------------------ = ------------- = 57 mph
1 hr 40 min 1 2/3 hr
Then m(t) = (rate)(time) = (57 mph)t This corresponds to Answer D.

Dividing my dog's age (X) by 4 and adding 6 is the same (=) as dividing my dog's age (x) by 8 and adding 8.
Answer:
∠1 = 23°
Step-by-step explanation:
∠WXZ = ∠WXY + ∠YXZ
Note that ∠2 = 4∠1 ( angle 2 is 4 times angle 1 )
Hence
4∠1 + ∠1 = 115
5∠1 = 115 ( divide both sides by 5 )
∠1 = 23°
