Answer:
Area: [tex]5x[/tex], Perimeter: [tex]2x+10[/tex]
Step-by-step explanation:
a)
We know that for any rectangle the area is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the area is [tex]x*5[/tex] or [tex]5x[/tex].
b)
We know that for any rectangle the perimeter is [tex]2(l+w)=l+w+l+w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the perimeter is [tex]2(x+5)=2x+10[/tex].
So, the answers are [tex]Area:5x,~Perimeter:2x+10[/tex]

Rewrite 19/8 as a mixed number.
Answer: 2 3/8
I got an A
Answer:
2 + 3/8
Step-by-step explanation:
Therefore we get 19 / 8 = 2 + 3/8 , which is written as 2 3/8 , called a mixed number. To convert 19/8 you do division; 8 into 19 goes 2 times with 3 left over; so 2 3/8.

Solve the inequality
-5/2(3x-2)<6-2x.
Show and explain every step.
Answer:
its true the answer is true but would u need a whole Paragraph like an explanation I could make one for you.
The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
What is inequality?
inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given inequality will be solved as below:-
( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x
Multiply the other hand by 2 and solve further.
( - 5 ) ( 3x - 2 ) < 2 ( 6 - 2x )
( - 5 ) ( 3x - 2 ) < ( 12 - 4x )
Take like terms to the same side and solve.
-15x + 30 < 12 - 4x
-15x + 4x < 12 - 30
-11x < - 18
x < 18 / 11
Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

James uses 1 1/2 cups of milk and 2 1/4 cups of flour for his favorite cookie recipe. This makes 60 cookies. How much milk and flour would he need to make 40 cookies?
Answer:
to get you answer you would have to add 1 1/2 and 2 1/4, then your equation would be 60 ÷ 3 3/4 , then whatever your total is, multiply that by 40 and that would be your answer
The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Rakim's goal is to have at least $500 in his checking
account at the end of the year. The table shows his
activity for the month of January. Will Rakim make his
goal if the month of January's activity is representative
of how much he will save and spend each month?
Explain.
Answer:
Each month he will save $ 50
Each month he will spend $1,250
Raking will have $600 in his checking account at the end of the year.
Step-by-step explanation:
1300 - 500 - 750 = $50
$50 x 12 month = $600
The required amount Rakim saves and sped each month is $50 and $1250.
Given that,
Rakim's goal is to have at least $500 in his checking account at the end of the year. The table shows his activity for the month of January. Will Rakim make his goal.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
Total money he has = 1300
Total money spend = 750 + 500 = 1250
Money he save = 1300 - 1250 = 50
For the condition of at end of the year he must have at least $500
So,
Yearly saving = 50 × 12 = $600, which greater than $500.
The required amount Rakim saves and sped each month is $50 and $1250.

The length of each side of a square is
represented by 2x - 1. Represent the
perimeter of the square.
Answer:
Perimeter = 4(2x - 1)
Step-by-step explanation:
Since the Perimeter of a square is 4L, it would be,
(2x - 1) + (2x - 1) + (2x - 1) + (2x - 1) which could also be shortened to 4(2x - 1)
Answer:
P = 4(2x - 1)
Step-by-step explanation:
Given that the side of each square is 2x - 1:
The formula for finding the perimeter of a square is:
P = 4s
where s represents the side of a square.
Substitute the given value for s into the perimeter formula:
s = 2x - 1
P = 4(2x - 1)
Therefore, the perimeter of the square is 4(2x - 1).

Answer:
1/4
Step-by-step explanation:
1. To find the slope, you can use the formula [tex]\frac{rise}{run}[/tex] to find it!
2. Rise means how many units you go up and down from point to point, and run means how far you go left or right from point to point.
3. Given the statement above, the rise would be 1, and the run would be 4.
4. Now, since slope is (rise)/(run), the slope is 1/4 because one divided by four is equal to one fourth.

If the temperature is 30, what is the temperature in Fahrenheit?
Answer:
The answer is 86° Fahrenheit.
Step-by-step explanation:
The equation for converting between Fahrenheit and Celsius is °F = 1.8 x °C + 32. So you would just plug 30 in for the °C.
°F = 1.8 x 30° + 32.
°F = 54 + 32
°F = 86°
Answer:
30ºC = 86ºF
Step-by-step explanation:
The temperature T in degrees Fahrenheit (ºF) is equal to 30 degrees Celsius (ºC) times 9/5 plus 32:
T(ºF) = 30ºC × 9/5 + 32 = 86ºF
Find the Mean, Median, Mode & Range. If possible, round to the nearest tenth. 3, 8, 7, 2, 4, 8, 3, 4
Answer:
Mean- 4.9
Median- 4
Mode- 3,4,8
Range- 6
Step-by-step explanation:
The mean of a sequence is the average amount. This is equal to all of the terms' sum divided by the number of terms. So, to find the mean add 2+3+3+4+4+7+8+8, which equals 39. Then, divide by 8 because that is the number of terms. Therefore, the mean is 4.9.
The median is the number in the middle of the sequence. To find the median order the sequence from least to greatest and find the middlemost number. In this case, that is 4.
The mode is the number that appears most often. In this sequence, 3, 4, and 8 all appear twice.
The range is the difference between the minimum and maximum. So, subtract 2 from 8 to get 6.
Flowers - Samantha and Maria purchased flowers. Samantha bought five roses for "r" dollars each and four daises for "d" dollars each. Altogether, Samantha spent $32 on flowers. Maria purchased one rose for "r" dollars apiece and six daisies for "d" dollars apiece - spending $22 total.

b) Solve the system to find the cost of roses and daisies. Use any strategy that you've learned.
Answer:

Solve for x.

Enter your answer in the box.
x =
Answer:
x=-1.5
Step-by-step explanation:
To solve for x, you need to rearrange so the x is on one side of the "=" by itself.
So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.
The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.
The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

medi Shashi Rimoko earns $620 per week as a chef. He has group
medical and dental insurance. Medical coverage costs $9,560
a year and dental coverage costs $172 a year. The restaurant
pays 80% of the medical and 65% of the dental insurance. How
much is deducted each week for insurance
Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.
The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:
= Amount x (1 - percentage paid by restaurant)
= 9,560 x ( 1 - 80%)
= $1,912
The amount he pays for Dental coverage is:
= Amount x (1 - percentage paid by restaurant)
= 172 x (1 - 65%)
= $60.20
The total amount he pays for insurance per year is:
= Medical + Dental
= 1,912 + 60.20
= $1,972.20
The weekly deduction is:
= Year amount / No. of weeks in year
= 1,972.20 / 52
= $37.93
In conclusion, $37.93 is deducted from his paycheck every week.
