8x-6 = 2x+ 24
A. subtract 6
U
B. subtract 2x
C. divide by 8
I D. add 6
E. subtract 30
Answer:
B. Subtract 2x
D. Add 6
Step-by-step explanation:
To solve this problem, isolate it by the term of x from one side of the equation.
8x-6=2x+24First, add by 6 from both sides.
[tex]\sf{8x-6+6=2x+24+6}[/tex]
Solve.
Add.
24+6=30
Rewrite the problem down.
[tex]\sf{8x=2x+30}[/tex]
You have to subtract by 2x from both sides.
[tex]\sf{8x-2x=2x+30-2x}[/tex]
Solve.
8x-2x=6x
Rewrite the problem down.
6x=30
Then, you divide by 6 from both sides.
6x/6=30/6
Solve.
Divide the numbers goes from left to right.
30/6=5
x=5
Therefore, the solution is x=5, which is our answer.
In the correct answer is B and D.

Answer:
(b) 64 sq. in.
Step-by-step explanation:
The shaded area is the difference between the overall area and the areas of the cutout corners.
The overall area is 10 in by 10 in, so is ...
A = s² = (10 in)² = 100 in²
The area of the cutout at each of the four corners is ...
A = s² = (3 in)² = 9 in²
So, the total area of the four cutouts is ...
cutout area = 4 × 9 in² = 36 in²
The remaining area is then ...
100 in² -36 in² = 64 in²

Answer:
10.7
Step-by-step explanation:
the tenth place is the first number that comes after the decimal so, that is the number you are rounding. We take a look following that number and it it is equal to or greater than 5, (which it is), we round up one number.
Answer:
10.7
Step-by-step explanation:
Any number between 1-4 rounds down and 5-9 rounds up, so here you will round up. I've included the decimal places as well below. The number after the decimal point is the tenth's place.

Some college friends have decided to go on a road trip over the summer with some friends. Finances are tight and they need to hire a car for the trip. There are two hire companies to choose from: Crazy Curly's charges a base fee of $20 and then 30 cents per mile. Bill's Beauties charges 20 cents per mile and a base fee of $50. - Write a system of equations that can be used to determine at what trip distance Bill's and Curly's rental cost would be the same. - At what trip distance would Bill's and Curly's rentals cost the same amount?
Answer:
300 milesStep-by-step explanation:
Let
y- the amount of charge, x - the number of milesThe equations as per question are below
Crazy Curly's
y = 0.3x + 20Bill's Beauties
y = 0.2x + 50Solve the system by substitution
0.3x + 20 = 0.2x + 500.3x - 0.2x = 50 - 200.1x = 30x = 30/0.1x = 300Beverly's average mark for nine examination papers was 89.5. How many marks did she score altogether?
Answer:
805.5 out of 900
Step-by-step explanation:
A test is out of 100 and because there are 9 tests: 9 x 100 which equals 900.
To get the average we add up each test mark and divide by the number of tests. The same can be applied here but reversed. So because there were 9 tests we can multiply 89.5 by 9 which gives us 805.5. Beverly scored 805.5 marks out of 900 which makes her average 89.5% for 9 tests.

Answer:
f(9.5) = 558.02.
Step-by-step explanation:
Because it is an exponential function, it can be written: y = (a)(b)^x
Now substitute in the two known points:
72 = (a)(b)^7.5 and
2 = (a)(b)^4 : => since 2 = (a)(b)^2 divide the left side by 2 and the right by (a)(b)^2
72/2 =[(a)(b)^7.5]/[(a)(b)^4]: => the (a) cancels out and b becomes b^(7.5–4)
36 = b^3.5: => To isolate b take the 3.5 root of both sides
{3.5 root}(36) = {3.5 root}(b^3.5)
2.783927 = b
Now to solve for a
2 = (a)(b)^4 => 2 = (a)(2.783927)^4 => 2 = (a)(60.066375) divide both sides by 60.066375 0.0332965 = a
Equation: y = (0.0332965)(2.783927)^x
Now plug in 9.5 for x
(0.0332965)(2.783927)^9.5 = 558.0178525 = 558.02
Using technology, determine the semi-annual payment on a 3 year loan of $8,561 at 9. 1% compounded semi-annually. Round your answer to the nearest cent. A. $1,662. 47 c. $1,925. 92 b. $1,914. 11 d. $1,991. 12.
The semi-annual payment is $1662.47
What will be the semi annual payment?Given : A 3 year loan of $8,561 at 9.1% compounded semi-annually.
We have to determine the semi annual payment.
We know,
[tex]P=\dfrac{PV.r}{1-(1+r)^{-n}}[/tex]
Where PV is present value of loan.
r is rate of interest
n is time period.
Given loan is calculated semi annually,
So PV = $ 8561
r=9.1 % =9.1/200
and time period is 3 years = 6 number of period as semi annually.
Thus, Substitute,
We get,
[tex]P=\dfrac{8561(\dfrac{9.1}{200})}{1-(1+\dfrac{9.1}{200})^{-6}}[/tex]
[tex]P=1662.47[/tex]
Hence the semi-annual payment is $1662.47

In order to manipulate a, you have to divide by 3 on both sides.
Consider this scaled figure of a swimming pool. The dimensions of the original pool are 24 feet wide by 36 feet long. A rectangle has a width of 6. 4 feet and width of question mark feet. Use the measurements of the original and of the scaled figure to find the scale factor and the missing length. What is the scale factor? What is the missing length of the scale model?.
The scale factor used for scaling the actual rectangular pool was 4/15 and the length of the scaled rectangle is 9.6 feet.
How to calculate the scale factor?Suppose the initial measurement of a figure was x units.
And let the figure is scaled and new measurement is of y units.
Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.
Then we have:
[tex]s \times x = y\\s = \dfrac{y}{x}[/tex]
Thus, scale factor is the ratio of the new measurement to the old measurement.
For this case, we're specified that:
Dimensions of the original pool = 24 feet wide by 36 feet long
The scaled rectangle's dimension: 6.4 feet width and L feet length (we assume the length be L units).
So, in scale drawing, 24 feet was converted to 6.4 feet. Let the scale factor be 's', then:
[tex]6.4 = s \times 24\\\\s = \dfrac{6.4}{24} = \dfrac{4}{15}[/tex]
Thus, since length is also scaled by same factor(as the whole figure is scaled by constant scale factor assumingly), we get:
Scaled length = s times original length
[tex]L = \dfrac{4}{15} \times 36 = 9.6 \: \rm feet[/tex]
Thus, the scale factor used for scaling the actual rectangular pool was 4/15 and the length of the scaled rectangle is 9.6 feet.

2. Write a recursive formula for the sequence 5, 18, 31, 44, 57, ... Then find the next term.
Answer: a6=70
Step-by-step explanation:
we know that
In the Arithmetic Sequence the formula is:
an= a1 + d(n−1)
where
a1 is the first term
d is the common difference
n is the number of terms
in this problem
a1=5
a2=18
a3=31
a4=44
a5=57
so
d=a2-a1 or a3-a2 or a4-a3 or a5-a4
d=57-44----> 13
find a6
a6= a1 + d(n−1)
n=6
d=13
a1=5
a6=5+13*(6-1)----> a6=5+13*5----> a6=70
Answer:
A1=5;an=an-1+13. The next term is 70Fine The Gradient of the curve xy=6, at point 1 & 6.

B. x can be factored from each term of the trinomial to obtain x(x^2+x-2),which is completely factored.
C. x can be factored from each term of the trinomial to obtain x(x^2+x-1), and the resulting trinomial can be factored to obtain x(x+2)(x+1), which is completely factored

Answer:
D. The trinomial is equivalent to (x+2)(x-1)
Step-by-step explanation:
1. Factor out the common term x:
= x(x^2+x-2)
2. Factor the equation:
= x(x - 1)(x + 2)
From this, we can see that because the equation was factorable, it is not prime. Option B is not completely factored, so it is incorrect. The final ordered pair shown in Option C is has (x + 1), when it should be (x - 1), so it is also incorrect. Option D is the true statement.
The terminal side of angle λ intersects the unit circle at point (-0.358, 0.934). Based on these coordinates, what is the approximate decimal value of cot(λ)
Answer: -0.383
Step-by-step explanation:
Since this is on the unit circle, the cosine is equal to the x coordinate and the sine is equal to the y coordinate.
Since cot = 1/tan = cos/sin, the approximate value is (-0.358)/(0.934), which is about -0.383.

you flip a coin and draw a marble at random from a bag containing two purple marbles and one white marble . what is the probability you flip a heads on the coin and draw a purple marble
Answer:
1/3 probability
Step-by-step explanation:
The probability that you flip heads is 1/2, one heads out of two possible (heads and tails).
The probability that you draw a purple marble is 2/3, two purples and three total (2 p +1 w).
To find the probability of both happening, multiply the probabilities together:
(1/2) * (2/3) = (2/6) = (1/3)
