Answer: x=230 and y=75
Step-by-step explanation: A triangle is worth 360 degrees, which means when you add up all the angles it equals 360 degrees. So
Second patio:
(x-10),60+80 = 360
x-10+140 =360-140
x-10=220+10
x=230
First patio:
(x+10)+(y+5)+40 = 360
x+y+55=360
x+y=360-55
x+y=305- x(230) =75
y=75
Answer: x = 50, y = 75
The sum of angles of a triangle is equal to 180°
according to the question, (x+10) + (y+5) + 40 = 180 -- eq(1)
(x-10) + 60 + 80 = 180 -- eq(2)
(x - 10) + 140 = 180
x - 10 +140 = 180
x + 130 = 180 , x = 180 - 130
x = 50
put x value in eq(1)
50+10 + (y+5) + 40 = 180
60+(y+5)+40 = 180
y+5 +100 = 180
y + 105 = 180
y = 180 - 105
y = 75
So, x = 50 and y = 75.

How do u find a equation passing through the line in a graph, I will give an example (-2,0) and (0, 5), I don’t understand how to calculate it can u please give me a easy way to do it for me , I’m in the 8th grade
Answer:
y = 5/2x + 5
Step-by-step explanation:
To find the equation, you first need to find the slope. You can do this by subtracting the two y coordinates (the two last numbers) and using that as the numerator (the top number of the fraction), and then subtracting the two x coordinates (the two first numbers) and using that as the denominator (the bottom number of the fraction). You then have the fraction -5/-2, which can be changed to 5/2 because they are both negative numbers. That is your slope. You then need to find the y-intercept (where the line connects with the y-axis). To do this, you need to figure out what the y (the second number) is when the x (the first number) is 0. In this example, you can already see with the second set of coordinates that the y-intercept is 5 because the x is 0. When this is not easily shown, you can figure out the y-intercept with a table. Sorry if I made it sound too complicated :)

A gas company charges a $16 monthly service fee and $0.6924 per hundred cubic feet of natural gas used during a month. Which equation best represents Y, the gas company’s monthly charged in dollars for using X hundred cubic feet natural gas?
A. Y = 0.6924x - 16
B. Y = 16x + 0.6924
C. Y = 16x - 0.6924
D. Y = 0.6924 + 16
The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:
Y = 0.6924X + 16
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:
Y = 0.6924X + 16
Now,
Option A has the correct variable coefficients, but the constant term is negative, which is not correct as a monthly service fee is always positive.
Option B has the correct constant term but the variable coefficient is positive, which doesn't make sense as the company charges per hundred cubic feet of natural gas used.
Option C has a similar problem as option A.
Option D has incorrect variable and constant terms.
Therefore,
The correct equation is Y = 0.6924X + 16.

is a negative number? Explain your answer. Include an example with numbers to support your explanation.
Answer:
x < - 5Step-by-step explanation:
Given equation:
5 + x = nIf n is negative then we get:
n < 0 or5 + x < 0x < - 5If n is negative then x is less than - 5.
Example:
x = - 6 ⇒ 5 + (-6) = 5 - 6 = - 1 ⇒ -1 < 0Answer:
x < -5
Step-by-step explanation:
Now the value of x is,
→ 5 + x = n
→ x = n - 5
The value of n when negative,
→ n < 0 ---- {n = 0}
When n is a negative number,
→ x < 0 - 5
→ [ x < -5 ]
Hence, the answer is x < -5.

1. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other
2. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. A proportion is an equation that states that two ratios or rates are equivalent.
3. As defined in the lesson on Unit Rate and Proportionality, the unit rate is the rate of change in a relationship where the rate is per 1.
4. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)
Angie bikes for 20 minutes burning 150 calories. How many minutes will it take to burn 525 calories?
Answer:
70 minutes OR 1 hour and 10 minutes (it's the same thing)
Step-by-step explanation:
So this can be modeled by the equation 20/150=x/525
so solving for x, you have to say whats the most times that 150 will go into 525 without going over
the answer is 3
so 150x3=450 and 525-450=75
75 is one half of 150 so it would be 3.5
multiply 20 by 3.5 and you get 70 or 1 hour and 10 minutes since an hour is 60 minutes

5 Michael has $16.25 in the bank. He needs $108 to buy a video game. He finds he can
save $1.75 a week from his allowance. How many weeks must he save in order to have
enough to buy the game?
Answer:
53 weeks (rounded)
Step-by-step explanation:
First, subtract 16.25 from 108 (108 - 16.25), resulting in 91.75
Next, you divide. 91.75/1.75
You would get 52.42... but you would have to add a week to actually get the game.

Answer:
let the interior angle of a triangle be 4x,6x and 8x
According to the question,
The interior angles of the triangle=180
4x+6x+8x=180

A track team needed to run or jog 20 laps for their practice. Of the total 20 laps, Sara completed 45, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875. Identify the descending numeric order of the laps completed.
Answer:
59 keenan
58 Jamie
45 sara
0.875 trey
0.833 maya
The descending numeric order of the laps was completed as 59, 58, 45, 0.875,0.833
What is descending order?Descending order is defined as when numbers (or other items) are arranged from the largest numbers to the least numbers, it is said to be in descending order.
Sara finished 45 laps, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875.
We have the given numbers as:
45, 58, 59, 0.833, 0.875
we have to determine the descending order of given numbers
Here the largest numbers to the least numbers, it is said to be in descending order.
⇒ 59 > 58 > 45 > 0.875 > 0.833
Hence, the descending numeric order of the laps completed:
Keenan completed 59 laps
Jamie completed 58 laps
Sara completed 45 laps
Trey completed 0.875 laps
Maya completed 0.833 laps
