Answer:
88
Step-by-step explanation:
x + 49 = 137 (exterior angle of triangle is equal to sum of its opoosite two interior angles)
x = 137-49

Answer:
A: 6/8 B: 1 2/8
Step-by-step explanation:
1) Count the number on spaces between the lines and then you get your denominator (bottom number of a fraction or in all)
2) Count to the line the letter is on and that will get your numerator (top number of a fraction or part of the denominator)

Consider isosceles ΔXYZ.
Answers
Answer:
n = 3
XY = 39 ft
XZ = 39 ft
Step-by-step explanation:
If we rotate the triangle 90° to the right we can see that the congruent angles are now on the bottom, making it the "more commonly seen isosceles triangle" we know.
This means that the two legs will be congruent to each other, so we can set them equal and solve for n:
(9n + 12) = (15n - 6)
9n + 12 = 15n - 6
9n + 18 = 15n
18 = 6n
6n = 18
n = 3
Now we can plug this value of n (3) into one of the expressions to solve for the legs. Since they will be the same length we only need to do one, but I will do both to make sure my work is as correct as possible:
XY
9n + 12
9(3) + 12
27 + 12 = 39
XZ
15n - 6
15(3) - 6
45 - 6 = 39

Find the value of the variable.
A. 7
B. 3
C. 3.5
D. 1.5
Answers
Answer: 3.5
Step-by-step explanation:
It is an intersection of a tangent and a secant.
122=9(9+2a)
144=81+18a63= 18a3.5=a
Took test as well!
The numerical value of 'a' in the secant segment of the circle is 3.5.
What is the numerical value of 'a'?The secant-tangent power theorem states that "if a tangent and a secant are drawn from a common external point to a circle, then the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment."
It is expressed as:
( tangent segment )² = External part of the secant segment × Secant segment.
From the diagram:
tangent segment = 12 ft
The external part of the secant-segment = 9 ft
Secant segment = ( a + a + 9 ) = 2a + 9
To determine the value of 'a', we use the secant-tangent power theorem.
12² = 9 × ( 2a + 9 )
Solve for 'a':
144 = 18a + 81
144 - 81 = 18a
63 = 18a
a = 63/18
a = 3.5
Therefore, 'a' has a value of 3.5.
Option C) 3.5 is the correct answer.

Can any one help with y = 2x + 4
6x – 3y = -12 system by substitution I’m so confused??
I will give you 50points
Answers
Answer:
It's in the screenshot hope it helpsss
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
y = 2x + 4 Substitute this for y in the second equation
6x - 3y = -12
6x - 3(2x + 4) = - 12 Substitute this for y for 2x + 4
6x - 3(2x) -3(4) = - 12 Distributive property
6x - 6x - 12 = - 12
(6x - 6x) -12 = - 12 like terms together
0 - 12 = - 12 Simplify
-12 = -12 True equation so x is equal to any number and you have the same equation

convert mixed number 5/6 x 2 1/2
Answers
Answer:
2 and 1/12
Step-by-step explanation:
you need to take 2 1/2 and convert it to the common denominator of 6
so 1/2 * 3 = 3/6. and 2*6 = 12. add the 12 and 3 to get 15/6. which is equivalent to 2 1/2
so multiply 15/6 * 5/6 and get 75/36 to get or 2 and 3/36. reduce down to 2 and 1/12

How do I answer this ?
Answers
Step-by-step explanation:
when a variable depends on the product or quotient of two or more variables, it is a joint variation like in our case here.
F (e.g. gravity) varies directly with the masses of 2 objects (like 2 planets) and varies inversely with the distance to or between these objects.
so, the gravity between 2 planets gets stronger the more mass the planets have, but gets weaker the more distance there is between them.
there is only one constant considered in a joint variation statement. in our case : k

The amount of money in a saving account increase from $250 to $270 what is the precent increase of the money in the savings account
Answers
Answer:
8%
Step-by-step explanation:
percent increase = [ (difference between initial value and final value) ÷ initial value] x 100
⇒ percent increase = [ (270 - 250) ÷ 250] x 100 = 8%
Answer:
12.5
Step-by-step explanation
270 - 250 = 20
250 divided by 20 = 12.5
So therefore the percentage in the increase is 12.5
