A formula is given, along with values for all but one of the variables in the formula. Find the value of the variable that is not given. Round to the nearest hundredth when necessary.
-d = rt; t = 5, d = 35
A)r = 40
B)r = 7
C)r = 30
D)d = 7

Question

Quizplus · Accepted Answer

d = rt, t = 5, d = 35

Substitute the given values: 
35 = r(5)

Solve for r: 
r = 35/5 
r = 7

Therefore, r = 7. Substituting the given values into the formula, we get:
35 = r(5)
Solving for r, we divide both sides by 5:
r = 7
Therefore, the value of r is 7.
