X=49 because 50-1=49 so 49+1=50
N mathematics, value may refer to several, strongly related notions.
In general, a mathematical value may be any definite mathematical object. In elementary mathematics, this is most often a number – for example, a real number such as π or an integer such as 42.
The options are:
(A)
(B)
(C)t= a(f -v)
(D) t= v(f-a)
Answer:
(A)
Step-by-step explanation:
Given the equation f=V+at which represents the final velocity of an object(f) with an initial velocity, V and an acceleration rate, a, over time, t.
We are required to solve for an equivalent equation with t as the subject.
In f=V+at
To make t the subject
Step 1: Subtract v from both sides
f-v=v-v+at
at =f-v
Step 2: Divide both sides by a
The correct option is A.
