8x-7=-5x+19 denklemini sağlayan, x'in değeri kaçtır?
Answer: X=2
Step-by-step explanation:
8x-7=-5x+19
=> 8x+5x=19+7 [Transforms]
=> 13x=26
=> x=26/13
So, x=2

Answer:
[tex]y = \frac{2}{5} x + 3[/tex]
Step-by-step explanation:
2x - 5y = -15
Firstly, you will need to isolate the variable you are solving for, in this case, y.
2x - 2x - 5y = -15 - 2x
-5y = -15 - 2x
-5y/-5 = -15/-5 - 2x/-5
A negative divided or multiplied by a negative is positive.
[tex]y = 3 + \frac{2}{5} x[/tex]
Rearrange.
[tex]y = \frac{2}{5} x +3[/tex]

Enrique has $50 in his lunch account and spends $5 per day from the account. Maya has $46 in her lunch account and spends $4 per day from the account. Which equations model the situation?
50 – 5x = y and 46 – 4x = y
5x + 50 = y and 4x + 46 = y
5x – 50 = y and 4x – 46 = y
5 – 50x = y and 4 – 46x = y
Answer:
50 – 5x = y and 46 – 4x = y, is your answer

Kira drove 522 miles in 9 hours.
At the same rate, how many miles would she drive in 7 hours?
GIven:522 miles in 9 hours.
So if we divide 522 by 9 we get that Kira drives 58 miles per hour.
Now in 7 hours Kira just drives 7 times that which means Kira drives.
58*7=406 miles
Hope this helped!
Step-by-step explanation:
Distance travelled in 9 hours = 522 miles
Distance travelled in 1 hour = 522/9 = 58 miles
Distance travelled in 7 hours = 7 * 58 = 406 miles
Hope it will help :)

Step-by-step explanation:
After 5 hours, how far apart are the boats? Label the distance(s) on your drawing from the first problem.
Answer:
The distance between them is 277.84 m
Step-by-step explanation:
See comment for complete question.
Given
Boat A:
[tex]Speed = 24mph[/tex]
[tex]\angle A = 340^{\circ}[/tex]
Boat B:
[tex]Speed = 35mph[/tex]
[tex]\angle B = 200^{\circ}[/tex]
[tex]Time = 5hr[/tex]
First, we calculate the distance traveled by both boats in 5 hours
[tex]Distance= Speed * Time[/tex]
[tex]Boat\ A = 24mph * 5hr = 120m[/tex]
[tex]Boat\ B = 35mph * 5hr = 175m[/tex]
For more clarity, I'll make use of the attached image to represent the system.
From the attachment, we are to calculate distance C, but first we calculate the angle between them.
[tex]\theta = 340^{\circ} - 200^{\circ}[/tex]
[tex]\theta = 140^{\circ}[/tex]
C is then calculated using cosine law:
[tex]C^2 = A^2 + B^2 - 2BC\ Cos\theta[/tex]
This gives:
[tex]C^2 = 120^2 + 175^2 - 2*120*175\ Cos(140^{\circ})[/tex]
[tex]C^2 = 120^2 + 175^2 - 2*120*175*-0.7660[/tex]
[tex]C^2 = 14400 + 30625 + 32172[/tex]
[tex]C^2 = 77197[/tex]
Take square root of both sides:
[tex]C = \sqrt{77197[/tex]
[tex]C = 277.84[/tex]
The distance between them is 277.84 m
a zoo has two fewer elephants then zebras and five times more monkeys then elephants. the total number of elephants, monkeys, and zebras is 30
4 elephants
20 monkeys

5(e) = monkeys
5(4) = 20 monkeys
20 + 4 + 7 = 30

Ali Clara and Shane raise money for new books for the school library all Ellie rays 20% more than Clara and $58 more than Shan Claries 1/4 times
Answer:
a. $435
b. 33.33%
Step-by-step explanation:
P.S - The exact question is -
Let Clara raised money = x
As given,
Ali raised 20% more than Clara
⇒Ali raised money = [tex]x + \frac{20}{100}x = x + \frac{1}{5} x = \frac{6}{5}x[/tex]
Also given,
Clara raised [tex]\frac{1}{4}[/tex] times more than Shan
Clara raised money = Shan raise money + [tex]\frac{1}{4}[/tex] times shan raired money
⇒Clara raised money = [tex]\frac{5}{4}[/tex] Shan raised money
⇒Shan raised money = [tex]\frac{4}{5}[/tex] times Clara
⇒Shan raised money = [tex]\frac{4}{5}[/tex] x
As given,
Ali raised $58 more than shan
⇒[tex]\frac{6}{5}x = \frac{4}{5}x + 58[/tex]
⇒[tex]\frac{6}{5}x -\frac{4}{5} x = 58[/tex]
⇒[tex]\frac{2}{5}x = 58[/tex]
⇒x = (29)(5) = $145
∴ we get
Clara raised money = x = $145
Ali raised money = [tex]\frac{6}{5}x[/tex] = $174
Shan raised money =[tex]\frac{4}{5}[/tex] x = $116
a.)
Total raised money = $145 + 174 + 116 = $435
b.)
Percentage of money Clara raised = [tex]\frac{145}{435}[/tex]×100% = [tex]\frac{1}{3}[/tex]×100% = 33.33%
A rectangular playground has an area of 3,394 square meters. If the width of the playground is 32 meters, find the length.
Answer:
106 square
Step-by-step explanation:
Area of rectangle = 3,394 square meters
Width = 32 meters
Length = ?
Area of rectangle = Length * Weight
3,394 = 32 * x
x = 3,394 /32
x = 106.0625
x = 106
The Length is 106 square

Find the perimeter of an equilateral triangle that has an attitude of 25 inches. Round your answer to the nearest 10
9514 1404 393
Answer:
86.6 inches
Step-by-step explanation:
The side length of an equilateral triangle is 2/√3 times the altitude. So, the perimeter is ...
P = 3s = 3(25)(2/√3) = 50√3 ≈ 86.6 . . . . inches
Charmaine has 17 cars available to rent. Let C be the number of cars she would have left after renting R of them.
Answer:
C = 17 - R
Step-by-step explanation:
In this scenario, 17 cars would be the initial starting point. While C would be the final number of cars, meaning that our equation would have to equal C. If she rents R number of cars then this number is being subtracted from the initial number of cars because Charmaine would no longer have them in his/her possession. Therefore, it is being subtracted. Using this information we can create the following equation.
C = 17 - R
