Answer:

Step-by-step explanation:
5(2x + 2) = 10
10x + 10 = 10
10x = 0
x = 0
Answer:
x = 0
Step-by-step explanation:
First, let's translate this statement into an equation.
5 times the sum of twice a number, x, and two means "5(2x + 2)"is ten means "= 105(2x + 2) = 10Solving
Step 1: Simplify both sides.
[tex](5)(2x)+(5)(2)=10[/tex] [tex]10x+10=10[/tex]Step 2: Subtract 10 from both sides.
[tex]10x+10-10=10-10[/tex] [tex]10x=0[/tex]Step 3: Divide both sides by 10.

Find the equation of a line parallel to y = 4x – 4 that contains the point (-2,0). Write the equation in slope-intercept
form.
Answers
Answer:
y = 4x + 8
Step-by-step explanation:
parallel mean the same slope so you can start with an equation of:
y = 4x + b
now we solve for b by inserting the coordinates and solving for b:
0 = 4 ( -2) + b
0 = -8 + b
8 = b
now put b into the equation:
y = 4x + 8
0=4x-4

The nth term of a sequence is 25 - 3n
Work out the first three terms of the sequence
Work out the first negative term of the sequence
Answers
Answer:
see explanation
Step-by-step explanation:
To find the first 3 terms substitute n = 1, 2, 3 into the formula
(a)= 25 - (3 × 1) = 25 - 3 = 22 = 25 - (3 × 2) = 25 - 6 = 19= 25 - (3 × 3) = 25 - 9 = 16
The first three terms are 22, 19, 16
Note the difference between consecutive terms is - 3
19 - 22 = 16 - 19 = - 3
Continuing this pattern
(b)16 - 3 = 13 13 - 3 = 10 10 - 3 = 7 7 - 3 = 4 4 - 3 = 1 1 - 3 = - 2
The first negative term is - 2

Daniel,Cheryl and Li Ying earned $550 from their part time jobs. Li Ying earned $28.Daniel earned 4 times as much as the total amount of Cheryll and Li Ying's earnings. How much did Cheryl earn?
Answers
The amount Cheryl earned from the per time job is $82.
The three of them earned $550 from their part time jobs.
Li Ying earned $28.
Daniel earned 4 times as much as the total amount of Cheryl and Li Ying's earnings.
let
x = amount Cheryl earned
y = amount Daniel earned
Therefore,
y = 4(x + 28)y = 4x + 112
y - 4x = 112
The three of them earned $550. Therefore,
x + y + 28 = 550x + y = 522
Let's combine the equation.
System of equationy - 4x = 112
x + y = 522
5x = 410
x = 410 / 5
x = 82
Therefore, Cheryl earned $82.

"The product of a six and a number increased by four is equal to
the product of twelve and the same number decreased by twenty."
Answers
Answer:
[tex] 6x + 4 = 12x - 20 [/tex]
[tex] x = 4 [/tex]
Step-by-step explanation:
Let "x" be the number.
Product of 6 and x (6*x), increased by 4 = [tex] 6x + 4 [/tex]
Product of 12 and x, (12*x), decreased by 20 = [tex] 12x - 20 [/tex].
Set both expressions equal to each other and solve for x as shown below:
[tex] 6x + 4 = 12x - 20 [/tex] (equation)
Subtract 12 from both sides
[tex] 6x + 4 - 12x = 12x - 20 - 12x [/tex]
[tex] -6x + 4 = -20 [/tex]
Subtract 4 from both sides
[tex] -6x + 4 - 4 = -20 - 4 [/tex]
[tex] -6x = -24 [/tex]
Divide both sides by -6
[tex] \frac{-6x}{-6} = \frac{-24}{-6} [/tex]
[tex] x = 4 [/tex]

An election poll of 1,000 people indicates that 48 percent of voters favor Candidate Smith and 50 percent of voters favor Candidate Jones, with a 3 percent margin of error. What can one conclude from this poll
Answers
The election poll indicates a close race between Candidate Smith and Candidate Jones, with a margin of error of 3 percent.
Given that,
Election poll of 1,000 people conducted
48 percent of voters favor Candidate Smith
50 percent of voters favor Candidate Jones
Margin of error is 3 percent
Based on the election poll,
We can conclude that there is a close race between Candidate Smith and Candidate Jones.
With Candidate Smith at 48 percent and Candidate Jones at 50 percent, it suggests a tight competition.
However, it's important to consider the margin of error of 3 percent.
This means that the actual support for each candidate could vary within this range.
Therefore, while this poll provides valuable insights, it is not definitive and other factors should also be considered.

The change in temperature from the morning to the afternoon is 7°F.
Given that, Alvin woke up in the morning, it was –9°F. By the afternoon, the temperature had risen to –2°F.
We need to find what was the change in temperature from the morning to the afternoon.
What is the change in temperature?Temperature change is a process whereby the degree of hotness of a body (or medium) changes.
You subtract the final temperature from the starting temperature to find the difference.
Now, change in teperature=-2-(-9)

Purchases made at small "corner stores" were studied by the authors of a certain paper. Corner stores were defined as stores that are less than 200 square feet in size, have only one cash register, and primarily sell food. After observing a large number of corner store purchases in Philadelphia, the authors reported that the average number of grams of fat in a corner store purchase was 21.8. Suppose that the variable
x = number of grams of fat in a corner store purchase
has a distribution that is approximately normal with a mean of 21.8 grams and a standard deviation of 7 grams.
a) What is the probability that a randomly selected corner store purchase has more than 29 grams of fat?
b) What is the probability that a randomly selected corner store purchase has between 15 and 25 grams of fat?

Fill in the blanks (including units where needed) and select the appropriate terms to complete the following statement about the temperature of the coffee in this case. At minutes after the coffee was put on the counter, its temperature is and will ? by about in the next 45 seconds.
Answers
Answer:
A) f'(t) is negative
B) degc/min
c ) At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds
Step-by-step explanation:
A ) f'(t) is Negative because as the cup of coffee is placed on the counter there is loss of heat from the cup of coffee to the surrounding as t increases hence f'(t) is negative
B ) The units of f'(20) = degc/min
C) At ║f'(20)║ = 1.5 and f'(20) = 56
║f'(20)║ = 1.5 represents the rate of change of temp every 20 minutes = 1.5
therefore after 45 seconds = 3/4 mins. change in temp = (3/4 * 1.5) = 1.125
At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds
