Step-by-step explanation:
1. use PEMDAS (Parentheses, Exponent, Multiplication & Division, Addition & Subtraction). you would do 3/4 divided by 3/8 first.
3/4 / 3/8 = 2
2. add 2 to -2 1/2 (or if it's easier to understand, do 2 minus 2 1/2)
-2 1/2 + 2 = -1/2 OR 2- 2 1/2 = -1/2
answer is -1/2

Step-by-step explanation:
Cesars net worth is 8,250.63 his liabilities are 3,222.35 what is cesars assets
Given parameters:
Net worth of Cesar = 8250.63
Liabilities = 3222.35
Unknown:
Cesar's asset = ?
Solution:
A person's net worth is their Assets minus liability;
Net worth = Assets - Liabilities
Assets = Net worth + Liabilities
For Cesar;
Assets = 8250.63 + 3222.35 = 11472.98
Cesar's assets is 11472.98
Y-2=7(X -4) what form of an equation is this? please and thank you <3
9514 1404 393
Answer:
linear equation in the point-slope form
Step-by-step explanation:
There are many forms an equation for a line may take. Some of the ones commonly seen are ...
ax +by = c . . . . standard form (a,b,c mutually prime integers; a>0)
y = mx + b . . . . slope-intercept form (m=slope; b=y-intercept)
y -k = m(x -h) . . . . point-slope form (m=slope, (h, k)=point)
__
and some additional ones I commonly use are ...
x/(x-intercept) +y/(y-intercept) = 1
y = m(x -h) +k . . . . variation of point-slope form (m=slope; (h, k)=point)
y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . two-point form (points (x1, y1) and (x2, y2))
bx -ay = bh-ak . . . . line perpendicular to standard form line ax +by = c through point (h, k)
__
If you compare these forms to the equation you're given, you see it matches the "point-slope form" for point (4, 2) and slope 7.

Theo solved n + 5 = 11 for the unknown. The steps he took are shown.
He started with 5 tiles.
5 tiles.
Then he added tiles as he counted up to 11.
6 tiles.
He realized he added 6 more tiles to his original 5 to make 11. So he found the unknown to be 6.
How could Theo check his work? Check all that apply.
He could substitute 5 for n in the original equation and add.
He could substitute 6 for n in the original equation and add.
He could subtract 5 from 11 and check that the answer is 6.
He could subtract 11 from 5 and check that the answer is 6.

Aiko jumped rope for an amazing 20 minutes. She stopped at 8:05. When did she start jumping?
Answer:
7:45 is when Aiko started jumping rope.
Step-by-step explanation:
If you start with 8:05 then subtract the 5 minutes you only have 15 minutes to calculate. Then you do 60 - 15 because there are 60 minutes in one hour. If you do that you are left with 45 and the hour would be 7 so the answer is 7:45

Jason and Eddy are traveling from Jacksonville to Miami, which is a distance of 382 miles. According to the American Automobile Association (AAA) map, it takes 1 hour and 54 minutes to travel from Jacksonville to Daytona, 2 hours and 51 minutes to travel from Daytona Beach to Fort Pierce, 1 hour and 23 minutes to travel from Fort Pierce to West Palm Beach, and 1 hour and 38 minutes to travel from West Palm Beach to Miami. If Jason and Eddy follow the AAA guidelines, what would be their average speed (in mph) for the trip
Answer:
The value is [tex]v = 49.23 \ mph[/tex]
Step-by-step explanation:
From the question we are told that
The distance from Jacksonville to Miami is d = 382 miles
The time it take to travel from Jacksonville to Daytona is [tex]t_1 = 1 \ hour\ and\ 54\ minutes = 1 + \frac{54}{60} = 1.9 \ hours[/tex]
The time it take to travel from Daytona Beach to Fort Pierce is [tex]t_2 = 2\ hours\ and\ 51\ minutes= 2 + \frac{51}{60} = 2.85 \ hours[/tex]
The time it take to travel from Fort Pierce to West Palm Beach is
[tex]t_3 = 1\ hour\ and\ 23\ minutes= 1 + \frac{23}{60} = 1.38 \ hours[/tex]
The time it take to travel from West Palm Beach to Miami [tex]t_4 = 1\ hour\ and\ 38\ minutes= 1 + \frac{38}{60} = 1.63 \ hours[/tex]
Generally the average speed is mathematically represented as
[tex]v = \frac{d}{t_1 + t_2 +t_3 + t_4 }[/tex]
=> [tex]v = \frac{382}{1.9 + 2.85 +1.38 + 1.63 }[/tex]
=> [tex]v = 49.23 \ mph[/tex]

A movie rental company charges a monthly fixed membership fee of $13 plus $4 per movie that the user rents in
that month. If M represents the number of movies that the user rents, and C represents the user's total charge
for the month, find the relationship between M and C.
Answer:
$17 dollars a month and the relationship is 3 apart
Step-by-step explanation:
Answer:
C=4M+13
Step-by-step explanation:
Remember that as the number of movies M increases, the cost C increases too. For each additional movie, the cost increases by $4. This is added to the monthly fixed membership fee of $13.
1/6x=-9 multiply each side of the equation by ___
6x + 9 = 4x - 3
2x + 9 =-3
Multiply both sides by 2
- 4(5x-7)=-18
5x - 7 = 4.5
Multiply both sides by-4
8 - 10x = 7+ 5x
4 - 10x = 3 + 5x
Multiply both sides by 1
x = 4
5x =- 16
Add to both sides
- 4x
12x + 4 = 20x + 24
Add to both sides
3x + 1 = 5x + 6

A pool measuring 8 meters by 24 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 720 square meters, what is the width of the path? 8 + 2x 8 24 - 2x
The Width of the path is ____ meters
The real answer is 6
Step-by-step explanation:
the width of the path is 6 meters.
Let's assume the width of the path is represented by 'x' meters.
The overall dimensions of the combined pool and path would be:
Width = 8 + 2x
Length = 24 + 2x
To calculate the area of the combined pool and path, we multiply the width and length:
Area = (8 + 2x) * (24 + 2x)
Given that the area is 720 square meters, we can set up the equation:
(8 + 2x) * (24 + 2x) = 720
Expanding the equation:
192 + 16x + 48x + 4x² = 720
4x² + 64x + 192 = 720
Rearranging the equation:
4x² + 64x - 528 = 0
Now we can solve this quadratic equation either by factoring, completing the square, or using the quadratic formula. After solving the equation, we find that x = 6.
Therefore, the width of the path is 6 meters.
