Just a answer with work will do, ill brainliest the best one.

Answer:

8.9

Step-by-step explanation:

This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.

We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.

w-20.5+20.5=8+20.5

w=28.5

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:

c-17=x>33

c=51

Step-by-step explanation:

The value of number c should be greater than 50.

It is given that difference of a number c and 17 is more than 33.

We have to find out the value of number c.

What do you mean by algebraic expressions ?

The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.

As per the question ;

The difference of c and 17 is more than 33.

i.e.,

difference of c and 17 meant ; 17 should be subtracted from c and this is greater than 33.

i.e.,

c - 17 > 33

c > 33 + 17

c > 50

Thus , the value of number c should be greater than 50.

Answer:

fractions that are the same

Answer: $5.19

Step-by-step explanation:

If there are 40 working hours in a week and 52 weeks in a year, 40 * 52 should be the amount of working hours in a year.

40 * 52 = 2080 working hours

Nate needs $900 to live each month and there are 12 months in a year, so $900 * 12 would equal how much he spends per year.

$900 * 12 = $10800

Divide $10800 by 2080 working hours to get how much he needs to make per working hour.

10800/2080 = approximately 5.19, rounded down from the nearest hundredth

He needs to make $5.19 per hour, so the answer is the last option.

Answer:

30

Step-by-step explanation:

Answer:

1.) B.) 30

2.) D.) 2.38

Step-by-step explanation:

1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.

2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:

Start:         Year 1:     Year 2:      Year 3:      Year 4:

$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

Answer:

1. Choose: 3

2. Choose: 144

3. Choose: 18

Step-by-step explanation:

The first thing you do is multiply 48 * 3/8= 18.  Then multiply 48 * 1/8= 6.  Then divide both answers to get 3, so 48 * 1/8 * 3.

Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).

Finally, to find the third Choose option, you divide the fraction 144/8 = 18.

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
