I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X
Answers
Explanation: The anglers in a triangle must all add to 180.
Therefore, we can use the equation 180=3x+28+5x+52+2x-10
Combing like terms gives us 180=10x+70
Solving for x gives us 11.
To check our work, we can plug in 11 for x.
3(11)+28+5(11)+52+2(11)-10=180.
Find each unit rate.

The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answers
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle

a. t = I/Pr
b. The value of t in the table is 3 years
Step-by-step explanation:
Solve for t in the formula.
I = Pr
~Divide pr to both sides
I/Pr = t
Using the formula above, we can solve for t.
75/(500)(0.05) = t
75/25 = t
3 = t

Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
Answers
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.
Step-by-step explanation:
Given that function 1 has the table;
x y
0 -2
2 0
3 1
5 3
Finding the slope of the linear function gives the rate of change of the function. In this case,
m=Δy/Δx
m=3-1/5-3 = 2/2 =1
The equation of the linear function is given as;
m=Δy/Δx
y-3/x-5= 1
y-3=x-5
y=x-5+3
y=x-2
y-intercept is -2
In function 2, the line passes through points (-2,0) and (0,4)
Finding the slope of the line,
m₁=Δy/Δx
m₁=4-0/0--2
m₁= 4/2 =2
Rate of change is 2
Finding the equation of the line
y-4/x-0 = 2
y-4=2(x-0)
y-4 =2x
y=2x+4
The y-intercept is 4
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.

it'll be really hard to show work so just trust me on this one-
hope it helps <3
For m^2 : because you are subtracting a positive from a negative, that means you are subtracting, so it would be -11m^2
For m : because you are subtracting a negative from zero, it would turn into a positive, making it just 5
For the constant : subtracting positive 8 from negative 9 makes it a positive from the double negative. Therefore you would add 8+9, giving you 17

Explain how to solve the equation and how to check the solution.
40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

Since this is a test, I'll give a hint.
This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.
If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?
You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.
