Answer:
x=25
Step-by-step explanation:
All angles in a triangle add up to 180°, so add all the angles together
(2x+15)+(x+10)+(3x+5)=6x+30
So that means... 6x+30=180°
Get rid of the 30, so... 180-30=150
6x=150°
Divide each by 6
6x/6=x
150/6=25
x=25
Sorry if that was hard to understand!!

Which graph shows four points that represent equivalent ratios?
Answers
Answer:
b
Step-by-step explanation:
Only option b from the available options represents equivalent ratios.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Equivalent ratios are the ratios that are the same when we compare them. Two or more ratios can be compared with each other to check whether they are equivalent or not.
The function of a line that shows the equivalent ratio always goes through the origin point of a cartesian plane.
The general form of the equation that shows the equivalent ratio:
Y = MX
Where M is Slope
therefore, From the given Options only option b is representing equivalent ratios.

Minimum, Vertex(1,-7) and sorry what do you mean by aos? i dont get that please type in the comments I'll answer that too. Hope you understand the rest
Step-by-step explanation:
The vertex of a parabola means the stationary point/turning point which is denoted by the following:
[tex]x=\frac{-b}{2a} \\[/tex]
and for y we just simply put the value of x that we get into the equation so lets get started
The equation [tex]y=x^2-2x-6[/tex] is a quadratic equation
and if we compare it by the standard form [tex]y=ax^2+bx+c[/tex] we get the following values
a=1 , b=-2 , c=-6
and now for the vertex
[tex]x=\frac{-b}{2a}[/tex]
[tex]x=\frac{-(-2)}{2(1)} \\x=\frac{2}{2} \\x=1[/tex]
and now for y
[tex]y=x^2-2x-6\\y=(1)^2-2(1)-6\\y=1-2-6\\y=-7[/tex]
so the vertex is (1,-7)
and the graph is minimum not maximum because the value of a is greater than 0 if the value of a>0 then the graph is minimum and if the value of a<0 meaning a is negative the graph is maximum and here in the equation a=1 which means a>0 then our graph is minimum.

Write a story problem in which you would have to multiply 5 × -1/3 to find the answer.
Answers
To convert Fahrenheit to Celsius, we first subtract 32. That gives us -3.
Then we multiply by 5/9 to convert to Celsius. When we do this, 3 goes into the denominator and we get -3/9 which is -1/3. Finally we multiply this fraction by 5: 5×-1/3=-5/3=-1.67°C or -1⅔°C.
So Jack was right. The negative value means the temperature is below zero, that is, below freezing. The temperature is 1⅔°C below zero.

√600 and ∛56 and show work
Answers
Answer:
√600 is around 24.5 while ∛56 is around 3.83
Step-by-step explanation:
Method: TRIAL AND ERROR
For √600, we can follow trial and error method:
30^2 is 900, so too big
20^2 is 400, so too small
25^2 is 625, too big
24^2 is 576, too small
Considering that 600 is between 24^2 and 25^2, we can try in between:
24.5^2 is 600.25, which is very close, therefore 24.5 is the answer
For ∛56, we can also follow trial and error method:
5^3 is 125
4^3 is 64
3^3 is 27
Considering that 56 is somewhere between 3^3 and 4^3, and that it's much more closer to 4^3, we can try 3.6^3, which is: 46.656;
3.7^3 is 50.6
3.8^3 is 54.8
3.9^3 is 59
3.85^3 is 57
3.84^3 is 56.6 (still larger)
3.83^3 is 56.1
So the answer is 3.83
But the method above works when using calculator, best for a calculator exam. If calculator is not allowed, you can find the difference between the two possible answers (e.g: 27 and 64 (3^3 and 4^3) following the above, to find out ∛56.) Of course, 56 is much nearer to 4^3, so we can assume that the answer is around 3.8.
Hope this helped. :)

Answers
Answer:
x = 6
x = -5
Step-by-step explanation:
Solving (1)
5x - 4 = 3x + 8
Bring variables to one side
5x - 3x = 8 + 4
The result is
2x = 12
Solve for x
½ * 2x = ½ * 12
x = 6
Solving (2)
-4x + 7 = -7x - 8
Bring variables to one side
7x - 4x = -7 - 8
The result is
3x = -15
Solve for x
⅓ * 3x = -15 * ⅓
x = -5
