Two times a number plus four is 22. What is the number?
2
6
9
11
Answer:
9
Step-by-step explanation:
22-4 = 18 ("plus four")
18/2 = 9 ("two times a number")
Answer: The correct answer is 9
Step-by-step explanation: Step 1: Subtract 4 from both sides.
2x+4−4=22−4
2x=18
Step 2: Divide both sides by 2.
[tex]\frac{2x}{2} =\frac{18}{2}[/tex]
x=9
If 2x-1 = 13, evaluate the expression below.
-x^2-4x
Answer:-77
Step-by-step explanation:cuz it is
Answer:
-77
Step-by-step explanation:
So with the first equation you are going to need to solve for "x". You are going to want to iqnore the secone expression till you solve for "x".
2x-1=13 add 1 on both sides +1 +1 2x=14[tex]\frac{2x}{2}=\frac{14}{2}[/tex] Then, divide 2 on both sidesWhich would give you "x=7"Now that you finish that solvign the first equation you are going to plug "7" into "x" in the expression shown below
[tex]-x^{2}-4x\\[/tex] [tex]-(7)^{2}-4(7)[/tex] we are going to solve the first part multiplying 7 by itself[tex]-7*7=-49[/tex] then we are going to solve the second part multiplying-4*7[tex]-4*7=-28[/tex] now we are going to add them both which gives us this. -49+-28=-77And that is how le9045 got -77.

3h(2) + 2k(3) evaluate
Answer:
6h + 6k
Step-by-step explanation:
To simplify the answer, we must first multiply:
3h x 2 = 6h
2k x 3 = 6k
Now we add the two:
6h + 6k
Since there are different variables and we can't simplify no more, the answer is:
6h + 6k

2. The following bar graph gives the percent of owners of three brands of trucks who are satisfied with their
truck. What is wrong with the way information is presented in this graph?
Answer:
Step-by-step explanation:
A histogram or a bar graph is used to show the big data having frequencies on the y-axis and range in which the data lie on x-axis.
In the given histogram there is no range of data.
Only percentage of customers who are satisfied with the different types of trucks have been given.
Therefore, to represent this data pie chart should be used instead of a histogram.

Jerry gave the cashier $40 to pay for 5 shirts. The cashier gave him$ 9.05 in change. Each shirt costs the same amount. What is the cost in dollars and cents for each shirt?
Answer: Each shirt costs 6.19
Step-by-step explanation:
You would have to do 40 - 9.05 and you would get 30.95 then you would have to divide 30.95 by 5 and then you get 6.19.
There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716. Find the number of orchestra seats and the number of balcony seats sold for the performance.
x = # of balcony seats
y = # of orchestra seats
We have to create a system of equations to solve this problem
x + y = 256
$8x + $12y = $2,716
We will solve this system of equations by elimination.
Multiply the first equation by -8
-8x - 8y = -2048
8x + 12y = 2716
Let's add the equations together
0 + 4y = 668
Simplify the left side
4y = 668
Divide both sides by 4
y = 167
We can subtract 167 from 257 to get the number of balcony seats.
257 - 167 = 90 balcony seats
There are 167 orchestra seats and 90 balcony seats
The number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716.
Let x be the number of Orchestra seats and y be the number of balcony seats. Then the equation will be
x + y = 257 ...1
12x + 8y = 2716 ....2
From equations 1 and 2, then we have
12x + 8(257 - x) = 2716
4x = 660
x = 165
Then the value of the variable y will be
165 + y = 257
y = 92
Thus, the number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
