Solve the equation x+10=30

Answers

Answer 1
Answer: get x alone on one side and solve

x = 30 - 10
x = 20
Answer 2
Answer: X+10=30
Subtract 10 from both sides
X+10=30
-10 -10
X=20
Answer:
X=20

An airliner travels 15 miles in 2 minutes.what is its speed in miles per hour

Answers

(15 miles / 2 minutes) times (60 minutes / 1 hour) = 15 x 60 / 2 = 450 miles per hour.
Remember:

1 mile per minute = 60 miles per hour

So:

(15 \ miles)/(2 \ min)=(15)/(2)*60=450 \ miles \ per \ hour

because you divide 187.15 by 19 and that will be what she makes for zero than you multiply 9.85 by 40 then you get 394

Thelma and Laura start a lawn-mowing business and buy a lawnmower for $225. They plan to charge $15 to mow one lawn. They would like to earn a profit of at least $750Part A: Define a variable to represent the unknown quantity in this situation.

Part B: Write an inequality to represent the amount of money charged per lawn, the cost of the lawnmower and the profit.

Answers

Answer:

I got  65

Step-by-step explanation:

The profit will be given as:

P=$15x−$225  

(where we subtracted the cost of the mower) so that  P=$750

x will be the required number of needed lawns.

We need to solve:

$750=$15x−$225  

rearranging:

x=$750+$225 /  $15  =65  lawns

If trapezoid JKLM is translated according to the rule (x, y) → (x + 8, y − 3), what are the coordinates of point L'?

Answers

The coordinate of point L' after translation is L'(6, -8)

Translation of coordinates

Given the coordinates of JKLM as J(-7,-2), K(-4,-2), L(-2,-5) and M(-9,-5)

Using the translation rule

(x, y) → (x + 8, y − 3)

The coordinate of point L' after translaton will be;

L' = (-2+8, -5-3)
L' = (6, -8)

Hence the coordinate of point L' after translation is L'(6, -8)

Another answer: According to the figure, the coordinates of JKLM are, J(-7,-2), K(-4,-2), L(-2,-5) and M(-9,-5) JKLM is translated to J'K'L'M' by means of the rule (x+8, y-3), we should know that (x, y) are coordinates of the pre image, to find the coordinates of each image we have (x', y') such that x' =x+8, and y' =y-3. Therefore, the coordinates of L' can be found by L'(-2+8, -5-3)=(6, -8) the final answer is L'(6, -8).

Find the range of {(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}.

Answers

Answer: The range is the output of our data, in standard notation represented as (x,y) where x is the input and y the output.

So the values of x are the domain, and the values of y are the range.

The set you give is :  {(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}

You can see that the range is : {-3, 5.9, 8.3}

Notice that in the set, the point y = -3 appears two times (in different pairs), but in the range only one, because you cant repeat the same value in one set.

range is output or y
(x,y)
the range is the 2nd number
when it repeats, don't list again
range=-3,5.9,8.3
