Answer:
x= -1
Step-by-step explanation:
make the equation to equal to zero and then bring 2 to left side of the equal sign. To get rid of (x), you simply divide both sides by 2 and you will get x= -1.
Value of x ?
X/2=8.5
Answer:
x=17
Step-by-step explanation:
to find x use this
[tex]\frac{x}{2} =8.5[/tex]
x=8.5*2=17
Answer:
x=17
Step-by-step explanation:
To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
x/2=8.5
x is being divided by 2. The opposite of division is multiplication. Multiply both sides by 2.
2*x/2=8.5*2
x=8.5*2
x=17
To check the solution, substitute 17 in for x in the original equation.
Original equation: x/2=8.5
Substitute 17 in for x: 17/2=8.5
17/2=8.5
8.5=8.5
This is true, so we know that x is equal to 17.

What is the surface area of the rectangular prism below?
15
A. 525 units2
B. 432 units2
C. 490 units2
D. 496 units2
Answer:
B ( 432 units^2)
Step-by-step explanation:
Total surface area= 2*(6*6)+ 4*(15*6)
There are 2 squares at each end of the same size so total area will be 2*(6*6)
If we look at the rectangles( bottom, top and the sides), we can see that all are of same dimensions and there are 4 of them so it's 4*(15*6)
In short, total surface area= 2*(6*6)+ 4*(15*6) = 432 units^2
why do bees eat flowers
Answer:
Bees dont comanly eat flowers. They take the pollen and necture inside the flower to polenate OTHER flowers.

To qualify for the postcard rate for postage, a postcard must be less than 4 1/2 inches high. Elayne has a postcard that is 4 7/8 inches high. How much is her postcard over the height limit?
Answer:
3/8 inches
Step-by-step explanation:
The postcard must be less than 4 1/2 inches high.
Elayne's postcard is 4 7/8 inches high.
We need to subtract the limit from the height of her postcard to know how high it is above the limit:
4 7/8 - 4 1/2 = 3/8
Her postcard is higher than the limit by 3/8 inches.
The answer is 3/4 or 1 1/2 inches.

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$ 7,299.92
Step-by-step explanation:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92

8/9 - 3/5 I am coming up with 5/4 am I right
Answer:
No, the correct answer is 13/45
Step-by-step explanation:
Find the greatest common factor and change the equations
8/9 -> 40/45
3/5 -> 27/45
40/45 - 27/45 = 13/45
13/45 is the correct answer
Which two transformations can be used to
obtain the graph of y = 3(x - 5)2 from the
graph of y = x2?
F. A vertical compression and a translation
5 units left.
G. A vertical stretch and a translation
5 units left.
H. A vertical compression and a translation
5 units right.
J. A vertical stretch and a translation
5 units right.
We have been given that that function [tex]y=3(x-5)^2[/tex] is obtained from the graph of [tex]y=x^2[/tex]. We are asked to find the two transformations that can be used to obtain the transformed function.
We will use transformation rules to solve our given problem.
[tex]f(x-a)\Rightarrow\text{Graph shifted to the right by a units}[/tex], where a is any positive number.
We can see that the value of a is 5 for our given function, therefore, graph is shifted to right by 5 units.
Now we will use scaling rules.
[tex]f(x)\Rightarrow a\cdot f(x)[/tex]
If [tex]a>1[/tex], then function is stretched vertically by a factor of 'a'.
If [tex]a<1[/tex], then function is compressed vertically by a factor of 'a'.
We can see that value of a is 3. Since 3 is greater than, so function will be stretched vertically by a factor of 3.
Therefore, the function can be obtained by a vertical stretch and translation of 5 units to right and option J is the correct choice.
When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?
Multiply each side by negative one over five , add 25 to each side
Multiply each side by 5, subtract 25 from each side
Multiply each side by negative one over five , subtract 25 from each side
Multiply each side by −5, add 25 to each side
Answer:
Multiply each side by −5, add 25 to each side
Step-by-step explanation:
-1/5(x-25) = 7
Multiply each side by -5/1 to clear the fraction
-5/1* -1/5(x-25) = 7*-5/1
x-25 = -35
Then add 25 to each side
x-25+25 = -35+25
x = -10

Astrid has a data plan through her cell phone company where she pays $49 a month for 5,000 kilobytes (KB) of data and $0.037 for each additional KB over 5,000. To the nearest cent, how much would Astrid need to pay for her data plan if she used 6,978 KB of data?
Answer: $122.19
Step-by-step explanation:
Hi, to answer this, first we have to calculate the additional KB that Astrid used:
KB used- KB limit=
6,978-5,000 = 1,978
Then, the cost of the plan is equal to a fixed fee (49) plus the product of the number of additional KB over 5,000(x) and the cost per KB (0.037).
Cost = 49+ 0.037 x
Substituting x =1,978
C = 49+ 0.037 (1,978)
C =49+73.186
C=$122.19

The low temperatures for the week in Carrollton, in degrees Fahrenheit (°F), were 17, 41, 11, 14, 11, 13, and 15. What is the mean of the temperatures without the outlier?
Answer:
The mean of the temperatures is 13.5 without the outlier.
Step-by-step explanation:
To find the mean, you add all of the numbers in your data set and divide that by how many numbers you added.
Before we do this, we must first identify the outlier and remove it from our calculations since it is asking us to find the mean without it. 41 is the outlier because it is a considerably larger number than the other numbers in the data set.
Equations: 11 + 11 + 13 + 14 + 15 + 17 = 81
81 ÷ 6 = 13.5
Kiyo is designing a rectangular garden with a 2-ft wide path all the way around it.
The length of the garden is 3 times as long as the width. Kiyo models the area of
his garden and the path with the equation f(x) = (x + 2)(3x + 2). Explain Kiyo’s error.
Answer:
38 ft
Step-by-step explanation:
Let x and (3x+2) represent the width and length respectively:
L + W = P/2 = 100/2 = 50
(3x+2) + x = 50
4x = 48
x = 12ft, the width, the length is 38ft
Answer: Kiyo only accounted for one side of the path when creating his equation. There are 2 feet of path on each side of the garden, meaning there should be 4 extra feet added to each expression multiplied.
Step-by-step explanation:
The rectangular path surrounding the garden is 2 feet on each side.
The length of the garden is represented by 3x, but when the length of the path is included, there is 2 feet of path on the left of the garden and 2 feet of path on the right.
Due to this, Kiyo made the mistake of only including 2 feet instead of the full 4 of the path by only accounting for one side of the path.
The correct equation is:
[tex]f(x) = (x+4)(3x+4)[/tex]
