−2(x+14)+1=5
Answers
Answer:
x=-16
Step-by-step explanation:
−2(x+14)+1=5
Step 1: Simplify both sides of the equation.
−2(x+14)+1=5
(−2)(x)+(−2)(14)+1=5(Distribute)
−2x+−28+1=5
(−2x)+(−28+1)=5(Combine Like Terms)
−2x+−27=5
−2x−27=5
Step 2: Add 27 to both sides.
−2x−27+27=5+27
−2x=32
Step 3: Divide both sides by -2.

A 38-ounce bottle of juice drink contains 6 percent water. Than computed 6 percent of 38. His work is shown below.
6 percent of 38 0.6 times 38 = 22.8
Which statement explains Than’s error?
Than did not multiply 0.6 and 38 correctly.
Than did not use 0.06 for 6 percent.
Than did not move the decimal point three places to the left in the answer.
Than did not use 6 for 6 percent.
Answers
Answer: Than did not use 0.06 for 6 percent.
Step-by-step explanation:
From the question, we are informed that Than computed 6 percent of 38 as 6 percent of 38 = 0.6 times 38 = 22.8.
His above solution is wrong. We should note that:
6% × 38
= 6/100 × 38.
= 0.06 × 38
= 2.28
The mistake that he made was that Than did not use 0.06 for 6 percent.

Write a polynomial for the given real-world situation. If the length of a rectangle is 3x^2-4x+5 and the width is 2x + 1, write and simplify a polynomial expression for the area of the rectangle. 3 points for mathematical process and 2 points for correct answer.
Answers
Answer:
[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]
Step-by-step explanation:
Given that:
Length of a rectangle = [tex]3x^2-4x+5[/tex]
Width of rectangle = [tex]2x + 1[/tex]
To find:
Simple polynomial expression for finding the area of rectangle.
Solution:
First of all, we should know about the formula for finding the area of rectangle. Then we should know how to multiply two polynomials.
Formula for area of a rectangle in terms of its length and width is:
[tex]Area= Length \times Width[/tex]
Putting the given values:
[tex]Area = (3x^2-4x+5)(2x+1)[/tex]
Here, we can use the distributive property of multiplication for finding the value of the above multiplication expression.
[tex](A+B)\times (C+D) = A\times C + A\times D+ B\times C + B \times D[/tex]
Therefore, the multiplication of above polynomials can be written as:
[tex]Area = (3x^2-4x+5)(2x+1)\\\Rightarrow Area = 3x^2(2x+1)-4x(2x+1)+5(2x+1)\\\Rightarrow Area = 6x^3+3x^{2} -8x^{2} -4x+10x+5\\\Rightarrow Area = 6x^3+-5x^{2} +6x+5[/tex]
Therefore, the answer is:
[tex]Area = 6x^3+-5x^{2} +6x+5[/tex]

65% of 40 is what number?
ahh this was supposed to be done yesterdayyy..
Answers
Answer:
65% of 40 is 26
26 is answer
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 40.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$40=100\%$.
Step 4: Similarly, $x=65\%$.
Step 5: This results in a pair of simple equations:
$40=100\%(1)$.
$x=65\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{40}{x}=\frac{100\%}{65\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{40}=\frac{65}{100}$
$\Rightarrow x=26$
Therefore, $65\%$ of $40$ is $26$

4 bells toll together at 9 am. They toll after 7, 8. 11 and 12 seconds respectively. How many times will they toll together again in the next 3 hours?
Answers
Answer:
5 times
Step-by-step explanation:
What we need to do here is to find the lowest common multiple of 7,8,11 and 12
This is;
1848
Now, let’s calculate the number of seconds in 3 hours
In 1 hour, we have 3600 seconds
In 3 hours, this will be;
3600 * 3 = 10,800 seconds
So, to find the number of times in which all 4 will toll together, we need to know the number of 1848 seconds in 10,800 seconds
Mathematically, that will be;
10,800/1848 = 5.844
Our answer will be 5 times however
This is because the sixth time they would have sounded together would be more than the 3 hours time frame

Drake is saving money to buy a new computer for $1,200. He already has $450 and plans $30 a week. The function y = 30x + 450 represents the amount Drake has saved after x weeks. How many weeks will it take Drake to save enough money to buy the computer?
Answers
Answer:
25 weeks
Step-by-step explanation:
step 1. find y which is what you are trying to find which is how long it will take for drake to make $1200
step 2.- subtract 450 from each side
1200=30x+450
-450 -450
750=30x
step 3.- divide by 30 on both sides
750=30x

Write an equation for the nth term of the geometric sequence 2, 8, 32, 128, ...
Then find a6. Round to the nearest tenth if necessary.
Answers
Answer:
Equation: x(n)=2*4^(n-1)
a6=2048
Step-by-step explanation:
Take note that the common ratio is 4 because 2*4=8, 8*4=32, 32*4=128, and so on...
We will use the equation x(n) = ar^(n-1) where n represents the nth term, r stands for the common ratio, and "a" stands for the first term. We use (n-1) because ar^0 is for the 1st term
Given the first term is a=2, the common ratio is r=4, then we have the equation x(n)=2*4^(n-1)
So, 128*4=512 would be the 5th term, and the 6th term would be 512*4=2048
So a6=2048
We want to find an equation and the sixth term of the given geometric sequence.
The equation is:
[tex]A_n = 4*A_{n-1}[/tex]
And the sixth term is equal to 512
Geometric sequences.In a geometric sequence, each term is a constant times the previous term, so the general relation is:
[tex]A_n = k*A_{n-1}[/tex]
Here we can use any pair of consecutive terms to find the value of the constant, for example, if we use the first two, we have:
8 = k*2
8/2 = 4 = k
Now we know the value of the constant, then the general formula is:
[tex]A_n = 4*A_{n-1}[/tex]
Now we can use this to get the sixth term:
[tex]A_6 = 4*A_5 = 4*128 = 512[/tex]

Answer:
-8(x^2 - 1)
Step-by-step explanation:
(x^2 + 3)^2 and (x^2 - 1)^2 are both squares of binomials. The first step here is to expand both:
-(x^2 + 3)^2 = -x^4 - 6x^2 - 9
(x^2 - 1)^2 = x^4 - 2x^2 + 1
Combine the two right-hand expressions, obtaining:
-8x^2 - 8 or -8(x^2 - 1)
This -8(x^2 - 1) is the simplest form of the given expression.
If desired, -8(x^2 - 1) can be factored: -8(x - 1)(x + 1)

Answer:
3.4 < x < 7.2
Step-by-step explanation:
The length of the third side of a triangle is always between the sum and difference of the lengths of the other two sides.
Here, the difference is 5.3 -1.9 = 3.4; the sum is 5.3 +1.9 = 7.2. So the length of the third side must satisfy ...
3.4 < x < 7.2
_____
Additional comment
The difference in side lengths is what you get when the shorter side is folded over the longer one. The excess of the longer over the shorter is the difference. If the triangle is to have non-zero area, the third side must be longer than that.
The sum of side lengths is what you bet when the two given sides are laid end-to-end. If the triangle is to have non-zero area, the third side must be shorter than that.
These statements are variations on the "triangle inequality", which states that the sum of any two sides must exceed the third. (That will always be the case if the sum of the shortest two sides exceeds the longest.)

Step-by-step explanation:
20 percent of 350 is 70, so adding that on will give us the price it is sold at for profit of 70 (20%).
Answer:
350 is our cost price and if we add our proft we get selling price
our profit=( 20/100)×350
i.e.70 so our profit is 70
then,
350+70= selling price
we get 420 as selling price
There are 37 students participating in an after-school program offering classes in yoga, bridge, and painting. Each student must take at least one of these three classes, but may take two or all three. There are 12 students taking yoga, 18 taking bridge, and 19 taking painting. There are 9 students taking at least two classes. How many students are taking all three classes

Step-by-step explanation:
You can solve this using the expression;
Total = A + B + C - Both - all - neither
Where A, B and C represent those taking one class
As each student must take at least 1 class, there is no 'neither'.
37 = 12 + 18 + 19 - 9 - All
37 = 40 - All
All = 40 - 37
All = 3
