Double bar graph is a bar graph that has two bars in it. On one bar, there is one set of data and on the other bar is the other set of the data on the graph.
In the options given above, the interest rate that has been charged on a weekly basis for the mortgages by a bank is an information that only provides one set of data and does not provide two sets of data.
Set up the equation:
Distribute 2x to both of the terms in parentheses:
The answer is
B.
Given situation:
Mr. jones received 70% of the 1500 vote casts in an election
Question and solution
=> How many votes did Mr Jones received:
=> 1 500 is the total number of voters and 70% of it voted Mr. Jones.
SO let’s start solving to get the number of voters who voted him.
=> 70% = 70 / 100 = .70
=> 1 500 * .70
=> 1 050 , the number of voters who voted him in an election.
Answer:
The negative solution = x = -4
Step-by-step explanation:
Let the number be = x
The square of number = x²
The difference between the square of a number and 28 = x²-28
Given that the difference of the square of a number and 28 is equal to three times that number.
Thus, the equation becomes
subtract 3x from both sides
Thus, the negative solution = x = -4
