Jenny solved the equation 1 – (2x + 4) = –4x + 5. Her work is shown. 1 − ( 2 x + 4 ) = − 4 x + 5 Line 1: 1 − 2 x + 4 = − 4 x + 5 Line 2: 5 − 2 x = − 4 x + 5 Line 3: 2 x = 0 Line 4: x = 0 What is the correct solution to the equation 1 – (2x + 4) = –4x + 5? Re-solve the equation to find the correct solution.
Answer:
4Step-by-step explanation:
Given the equation 1 – (2x + 4) = –4x + 5, we are to find the correct solution of the equation;
Step 1: Open the parenthesis;
1 – (2x + 4) = –4x + 5
1-2x-4 = -4x + 5
1-4-2x = -4x +5
-3-2x = -4x + 5
Step 2: Collect like terms
-2x + 4x = 5 + 3
2x = 8
Step 3: divide both sides by 2;
2x/2 = 8/2
x = 4
Hence the correct value of x is 4

The water level in Ricky Lake changes at an average of -716 inch every 3 years. a. Based on the rate above, how much will the water level change after one year? Show your calculations and you can use the vertical number line to help you., using 0 as the original water level.
Answer:
The water level will change at a rate of - 2 7/18 inches per year
Step-by-step explanation:
From the question, we have a change of -7 1/6 inch every 3 years
We now want to calculate the value of the change every year
Mathematically, that will be;
- 7 1/6 divided by 3
= -43/6 divided by 3
= -43/18 = - 2 7/18 inch per year

Andy runs 436.8 meters in 62.08 seconds. If Andy runs at a constant speed, how can we find out how far he runs in each second? Explain what is happening mathematically to the decimal points in the divisor and dividend before dividing. Do not solve, just explain how you would begin to set up your problem. *
Answer:
7 meters per second.
Step-by-step explanation:
Given that,
Andy runs 436.8 meters in 62.08 seconds.
We need to find how far he run in each second. It can be calculated by dividing distance by time taken as follows :
[tex]x=\dfrac{436.8\ m}{62.08\ s}\\\\=7.03\ m/s[/tex]
or
x = 7 m/s
So, Andy will cover 7 meters per second.
Given f(x) = -4x2 +13x-2, what is the value of f(-1)?
Answer:
f(- 1) = - 19
Step-by-step explanation:
To evaluate f(- 1) substitute x = - 1 into f(x) , that is
f(- 1) = - 4(- 1)² + 13(- 1) - 2 = - 4(1) - 13 - 2 = - 4 - 13 - 2 = - 19

The denominator of a certain fraction is 6 more that the numerator,and the fraction is equivalent to 1/3. Find the numerator.
Answer:
Numerator = 3
Step-by-step explanation:
Let the numerator is x.
The denominator is 6 more that the numerator, 6+x
The fraction is equivalent to 1/3. ATQ,
[tex]\dfrac{x}{x+6}=\dfrac{1}{3}[/tex]
Cross multiplying both sides,
[tex]3x=x+6\\\\3x-x=6\\\\2x=6\\\\x=\dfrac{6}{2}\\\\x=3[/tex]
Numerator = 3
So, the numerator is 3.

The two rectangles shown below have the same
perimeter. Write and solve an equation to find the value of x. Then find the measures of the length and width of
Rectangle B. All measurements are in inches.
9514 1404 393
Answer:
x = 3length = 9width = 3Step-by-step explanation:
The sum of length and width is half the perimeter. If the perimeter is the same, so will be the sum of length and width:
7 + 5 = x + (4x -3)
15 = 5x . . . . . . . add 3, simplify
3 = x
The value of x is 3.
The length of Rectangle B is 4(3)-3 = 9 inches.
The width of Rectangle B is 3 inches.

Nick wants to purchase a pair of binoculars that is on sale for $155.75. The sales tax rate in his county is 6.5%. Calculate the amount of sales tax Nick will pay on the purchase. Round to the nearest cent if necessary.
Given:
Price of a pair of binoculars = $155.75
Sales tax = 6.5%
To find:
The amount of sales tax Nick will pay on the purchase to the nearest cent.
Solution:
According to the question,
Sales Tax value = 6.5% of Price of a pair of binoculars
[tex]=\dfrac{6.5}{100}\times 155.75[/tex]
[tex]=0.065\times 155.75[/tex]
[tex]=10.12375[/tex]
[tex]\approx 10.12[/tex]
Therefore, the amount of sales tax is $10.12.

(d) $14 Kiran have to deposit to pay debt.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
At the beginning, the money in Kiran's account = $24
(a)
Since, in the first week amount spend by Kiran on lunches = $16
Remaining amount = 24 - 16 = 8
(b)
Then Kiran deposits some money, then total amount in account becomes $28
Let Kiran deposits x amount
8 + x = 28
x = 20
(c)
Then Kiran spent $34 on lunches,
Remaining amount in Kiran's account = 20 - 34 = -14
(d)
Kiran has $14 debt,
To pay debt, Kiran needs to deposit $14.

Add one-half to 9 times p
Answer:
1/2 + 9(p)
Step-by-step explanation:
Answer:
[tex]\frac{1}{2}[/tex] + 9p
Step-by-step explanation:
add one-half can translate to +[tex]\frac{1}{2}[/tex], so we know that this needs to be in the expression somewhere
the "to" means that the sentences is going to state the next term in the expression
9 times p means 9 multiplied by p, and this can be written as 9p
so put our terms together to get [tex]\frac{1}{2}[/tex] + 9p
