based on your knowledge of word parts, complete the sentence with the correct word.
sam had to mix______parts of the two chemicals for the experiment.
a. equaled
b. equitably
c. equal
d. equate
e. equation

Explanation:

The sentence requires a verb in the past - tense form. "Equal" is an adjective or a verb (base form). "Equate" is a verb (base form). "Equitably" is an adverb. "Equation" is a noun. "Equaled" is the past - tense form of the verb "equal" (in the sense of being equal in quantity, measure, or value). Since the sentence is in the past - tense ("had to mix"), we need a past - tense verb.

Answer:

A. equaled
