Answer:
-3x-12
Step-by-step explanation:
Answer:
-3x-12
Step-by-step explanation:
This is a problem of distribution.
Distribute means to multiply the variable outside the perenthesis to what's inside the perenthesis.
What you are going to do is distribute the -3 to the x and 4
-3 times x is -3x
-3 times 4 is -12
Make sure the signs are correct and the new expression is -3x-12

Step-by-step explanation:
please find the value of x
Answer:
Step-by-step explanation:
A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.

The following is an incomplete paragraph proving that ∠WRS ≅ ∠VQT, given the information in the figure where segment UV is parallel to segment WZ:
Segments UV and WZ are parallel segments that intersect with line ST at points Q and R, respectively.
According to the given information, segment UV is parallel to segment WZ, while angles SQU and VQT are vertical angles. Angle VQT is congruent to angle SQU by the Vertical Angles Theorem. Because angles SQU and WRS are corresponding angles, they are congruent according to the Corresponding Angles Theorem. Finally, angle VQT is congruent to angle WRS by the ________ Property.
Which property of equality accurately completes the proof?
А Reflexive
B Substitution
C Subtraction
D Transitive
Answer:
The correct answer is Transitive
The ratio of money in Terry's bank account to Faye's bank account was 3:5.
Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did they initially have altogether?
Answer:
£780 and £1300
Step-by-step explanation:
The ratio in their accounts is 3 : 5 = 3x : 5x ( x is a multiplier )
Terry put £220 into his account, then 3x + 220
Faye withdrew £300 from her account then 5x - 300
They now have the same amounts in their accounts, thus
5x - 300 = 3x + 220 ( subtract 3x from both sides )
2x - 300 = 220 ( add 300 to both sides )
2x = 520 ( divide both sides by 2 )
x = 260
Thus initial amount in their accounts
3 × £260 = £780 ← Terry's account
5 × £260 = £1300 ← Faye's account
3. What do you notice?
What is the numerical coefficient of the a^4 b^4 term in the expansion of (1/3a^2 - 2b)^6
enter your answer, in the simplest fractional form, in the box
Use the binomial theorem:
[tex]\left(\dfrac13a^2-2b\right)^6=\displaystyle\sum_{k=0}^6\binom6k\left(\dfrac13a^2\right)^{6-k}(-2b)^k=\sum_{k=0}^6\binom6k\dfrac{(-6)^k}{729}a^{12-2k}b^k[/tex]
where
[tex]\dbinom nk=\dfrac{n!}{k!(n-k)!}[/tex]
is the binomial coefficient.
We get the a⁴ b⁴ term when k = 4, which gives the coefficient
[tex]\dbinom64\dfrac{(-6)^4}{729}=\boxed{\dfrac{80}3}[/tex]

The EPA wants to know the daily level of pollutant discharge in the manufacturing district in Pittsburgh for February 2005. The monitoring equipment reveals that the mean daily discharge per factory (calculated as total areal discharge divided by total areal factories) is 30.2 tons with a standard deviation of 9.1 tons. Construct a confidence interval for the true population mean of pollutant discharge using a 95% level of confidence.
Answer:
The 95% confidence interval for the true population mean of pollutant discharge is (26.7 tons, 33.7 tons).
Step-by-step explanation:
Let X represent the daily level of pollutant discharge in the manufacturing district in Pittsburgh.
The monitoring equipment reveals that for the 28 days of the February month
Mean daily discharge per factory, ([tex]\bar x[/tex]) = 30.2 tons
Standard deviation daily discharge per factory, (s) = 9.1 tons
Compute the critical value of t for 95% level of confidence and (n - 1 =) 27 degrees of freedom as follows:
[tex]t_{0.05/2, 27}=2.052[/tex]
*Use a t-table.
Compute the 95% confidence interval for the true population mean of pollutant discharge as follows:
[tex]CI=\bar x\pm t_{\alpha/2, (n-1)}\cdot\frac{s}{\sqrt{n}}[/tex]
[tex]=30.2\pm 2.052\times\frac{9.1}{\sqrt{28}}\\\\=30.2\pm 3.53\\\\=(26.67, 33.73)\\\\\approx (26.7, 33.7)[/tex]
Thus, the 95% confidence interval for the true population mean of pollutant discharge is (26.7 tons, 33.7 tons).
3. In the month of August, a car dealership sold a total of 72
cars and trucks. The dealership reported that for every 4
passenger cars sold, there were 2 trucks sold. How many of
each type of vehicle were sold in the month of August?
Answer:
The dealership sold in August 24 trucks and 48 cars
Step-by-step explanation:
Equations
A dealership reported they sold a total of 72 vehicles.
It also determined that for every 4 cars sold, they sold 2 trucks. It means that they sold twice as many cars as trucks.
Let x be the number of trucks sold.
It follows that 2x is the number of cars sold.
The sum of both numbers must equal 72:
x + 2x = 72
Simplifying:
3x = 72
Solving:
x = 72 / 3 = 24
The number of cars were
2x= 48
The dealership sold in August 24 trucks and 48 cars

a. 2% of 180
b. What percent is 17 out of 40
please help me!
Answer:
a. 3.6
b. 42.5%
Step-by-step explanation:
a. 180/100 = 1.8
1.8 times 2 (since it's 2%) gives us 3.6
B. 17/40 is 42.5
The value of 2% of 180 is 3.6.
The percent of 17 out of 40 is 42.50%.
Percentage can be described as a fraction out of an amount expressed as a number out of hundred. Percentages are represented with %.
In order to determine the value of 2% of 180, multiply 2/100 by 180.
2/100 x 180 = 3.6
In order to determine the percent of 17 out of 40, divide 17 by 40 and multiply by 100
(17/40) x 100 = 42.50%
