If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.
Answer:
A. 24
Step-by-step explanation:
1. 4 x 5 then 2. 18/3 then 3. - 2
Answer:
V=10−3y
Step-by-step explanation:
Solve for V by simplifying both sides of the equation, then isolating the variable.
Unclear question. However, I inferred you want to know about hypotehsis test.
Step-by-step explanation:
Remember, any hypothesis test is divided into two types. They are:
- the null hypothesis and
- the alternate hypothesis.
Using this question example, here's the hypothesis statements ma sound:
Null hypothesis; There is a significant impact by the explanatory variables on engine overhaul time.
Alternate hypotheses; There is no impact by impact by the explanatory variables on engine overhaul time.
