Step-by-step explanation:
Use the algebra tiles to model the equation 2x + 4 = 3x + (−1). Then complete the sentences. To model 2x + 4, you need:
1 answer:
The value of x would be 5 for the model 2x+4.
Rearrange unknown terms to the left side of the equation,
Combine like terms
By calculating the sum or difference : -x = -5
Lets divide both sides of the equation by the resulting coefficient 5
So x = 5

Question:
<em>A research center poll showed that 78% of people believe that it is morally wrong to not report all income on tax returns. What is the probability that someone does not have this belief? </em>
<em>The probability that someone does not believe that it is morally wrong to not report all income on tax returns is . (Type an integer or a decimal.)</em>
Answer:
Step-by-step explanation:
Given
Let p represent the given proportion
p = 78%
Required
Determine the probability that someone holds a contrary belief
Start by converting the given proportion to decimal
In probability, the sum of opposite probability is equal to 1
Represent the probability that someone holds a contrary belief with q
So;
Make q the subject of formula
Substitute 0.78 for p
<em>Hence, the probability that someone does not believe is 0.22</em>
