Answer:
Solve for x first.
In order to solve for x, you must set up an equation where the two interior angles (1 and 2) are equal to the exterior angle (3).
Interior angles.
Angle 1 = 3x + 7Angle 2 = 2x + 24Exterior angle:
Angle 3 = 6x + 10Set up the equation:-
(3x + 7) + (2x + 24) = 6x + 10
Group and combine like terms;
(3x + 2x) + (7 + 24) = 6x + 10
5x + 31 = 6x + 10
Get rid of constants;
-10 -10
5x + 21 = 6x
-5x -5x
21 = x, the value of 'x' is 21°.
Now we plug in the value of x into angle 3's equation.
∠3 = 6x + 10
∠3 = 6(21) + 10
∠3 = 126 + 10
∠3 = 136°, ∠3 = 136°.

Answer:
The values that are in the correct spots are: 82, 62, 163 and 300
Step-by-step explanation:
There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.
82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.
62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.
156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.

Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%.
Write an equation that represents the total cost, c, of any item bought in Idaho whose price is p
Answers
Answer:
c = 0.06p + p
Step-by-step explanation:
hope this helped
An equation that represents the total cost, c, of any item bought in Idaho whose price is p is c = 1.06p.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Cost of the winter jacket = $30
Sales tax = 6%
Total cost of the winter jacket = 30 + (6% × 30)
= 30 + 1.8
= $31.8
If the total cost of any item is c whose price is p,
c = p + (6% × p)
c = p + 0.06p
c = 1.06p
Hence the required equation is c = 1.06p.

Cube: edge = 2.5 feet
Cuboid: l = 7.5 ft, w= 15 feet, h= 7.5 feet
So, Volume of cubical box
= l³
= 2.5³
= 15.625 ft³
and, Volume of Cuboidal box
= lwh

Which is bigger, 1.2 or 1.18 repeating
Answers
Answer:
[tex]beinggreat78~here~to~help.[/tex]
Your answer would be that 1.2 is bigger.
Why is that the case?This is the case because the tenths place, the decimal farthest to the left, is greater than the compared tenths place, which has a 1
1 is greater than 2
With that information, 1.2 is bigger.
Comparing the two decimal approximations, we can see that 1.2 is bigger than 1.18 repeating (1.1818).
To compare 1.2 and 1.18 repeating (1.181818...), we can first convert 1.18 repeating to a fraction.
Let x = 1.181818...
Now, multiply x by 100 to remove the repeating decimal:
100x = 118.181818...
Subtract x from 100x to eliminate the repeating part:
100x - x = 118.181818... - 1.181818...
99x = 117
x = 117 / 99
Now, we simplify the fraction:
x = 13 / 11
Now that we have both numbers in decimal form, we can compare them:
1.2 ≈ 1.2 (rounded to one decimal place)
1.18 repeating = 13 / 11 ≈ 1.1818 (rounded to four decimal places)
Comparing the two decimal approximations, we can see that 1.2 is bigger than 1.18 repeating (1.1818).

what are the angles of a triangle with 73, x, x-11?
Answers
Answer:
The angles of the triangle are 73, 59, and 48
Step-by-step explanation:
The sum of a triangle's angles must always add up to 180
In order to find out the measure of x we must make an equation where 180=the sum of the angles
180=2x+62
We got the 2x and the 62 from combining like terms
x+x=2x
73-11=62
Now we simply use algebra and try to solo out the x
First, subtract 62 from both sides
118=2x
Then, divide both sides by 2
59=x
x=59
Then plug in 59 with x and this gives you
73, 59, and 48 which all together add up to 180
