Answer:

21

Step-by-step explanation:

straight line = 180 degrees ( H,D,R)

180 = 7x - 3 + 2x  - 6    

180 = 7x + 2x - 3 - 6     (group the same type number together)

180 = 9x -9           (simplify the numbers)

189 = 9x    (+9)

21 = x    (divide by 9)

The Harvey family stayed at a hotel for n nights. The cost was $80 per night plus a one-time fee of $20 because they brought their dog. Which expression represent the total cost of their hotel stay.

80n + 20n
80n + 20
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.

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

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.
