Answer:
Step-by-step explanation:
The missing angle and the exterior angle, a, must equal 180 so
a+8x-11=180
a=191-8x
The sum of all inner angles must equal 180 so
191-8x+2x+6+5x=180
-x+197=180
-x=-17
x=17

Step-by-step explanation:
d=2r=2·18=36m
Answer:
Your in luck! I'm actually learning this right now!
Step-by-step explanation:
d = 2r so basically your diameter is your radius times 2! So 18 x 2 = 36 so the answer should be 36 hope this helps!
True or False?
k = 2 is a solution to the inequality 8k+ 4 > 18.
Answers
Answer:
True
Step-by-step explanation:
If k = 2, then we plug in 2 for every instance there is a k. So...
8k + 4 > 18
Will turn into...
8(2) + 4 > 18
Then solve using PEMDAS (or whatever you were taught. Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.)
16 + 4 > 18
20 > 18
Since 20 is greater than 18, 2 can be a solution for this inequality.

A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answers
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day
Are the ratios 7:5 and 11:10 equivalent

80 + 20n
80 + 20 + n
Answers
Answer:
80n + 20
Step-by-step explanation:
20 stays the same because it's a one time fee. Then, for every night the Harvey family stays, it costs them eighty dollars. So, it's 80n + 20
Answer: 80n+20
Step-by-step explanation:
80 is the cost of nights you stayed but you don’t know the number of nights they dated so you place n next to 80 and they payed an additional 20 fee so you add that to 80n

Answer:
x = 2, y = 10, sides = 15
Step-by-step explanation:
The hash marks tell you all of the sides are the same length. You can use this fact to relate the side length expressions to each other to solve for the variables.
We see that x appears in the left and right expressions only. So we can find x by setting those expressions equal to each other.
8x -1 = 4x +7
4x = 8 . . . . . . . . . . . . . add 1-4x to both sides of the equation
x = 2 . . . . . . . . . . . . . . divide by 4; the value of x
8x -1 = 8(2) -1 = 15 . . . the length of the sides
Now, we can find y using an expression that involves y. The top expression is the simplest:
y +5 = 15 . . . . . the length of the side we just found
y = 10 . . . . . . . subtract 5
The variable values are ...
x = 2
y = 10
The side lengths are 15.
