4 0

Answer:

The first term is 42.

Step-by-step explanation:

The common difference is 142  - 140 = 2 so we have

50th term = a1 + 2(50 -1) = 140    where a1 is the first term

a1 + 98 = 140

a1 = 140 - 98 =  42.

Someone please help
julia-pushkina [17]

Answer:

(a) So the top of the hill is 365 feet above sea level.

(b) Checkpoint 5 is 185 feet higher than checkpoint 2.

Step-by-step explanation:

<u>Solution for (a):</u>

<u />

Checkpoint 2 is -218 feet above sea level.

The top of a hill rises 583 feet above Checkpoint 2.

The altitude of the top of the hill = -218 + 583 = 365

So the top of the hill is 365 feet above sea level.

<u>Solution for (b):</u>

<u />

Checkpoint 2 is -218 feet above sea level.

Checkpoint 5 is -33 feet above sea level.

Checkpoint 5 is -33 - -218 = 185 feet higher than checkpoint 2.

EXTRA POINTS :) what is the value of x??
vlada-n [284]

Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180°     then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180         subtract 10 from both sides

        -10     -10

10x = 170            divide each side by 10

/10     /10

x = 17
