Answer:
Therefore, x = -2m+4/-n-1
For the first question, simply make a right angle triangle with the following dimensions.
The angle of elevation or the angle from the ground between the first floor and ground is 60 degrees.
The height between the 2 floors is 26 feet.
Solve for the hypotenuse, or the diagonal length between the first and second floors.
Then for the second question, divide the length in feet by the rate to find the time it takes for the object to move.
Answer:
(-2,-2)
Step-by-step explanation:
solve by elimination
The required equation is <u>135 + 9x > 250</u>.
The number of lawns Ed must mow is assumed to be x.
The amount Ed charges for each lawn he mows is $9.
Thus, the total amount Ed earns by mowing x lawns = $9x.
The savings which Ed has is $135.
Thus, the total amount Ed will have to spend can be written as the expression, $(135 + 9x).
The cost of the video game is given to be $250.
We are asked to write an equation, that can be used to find the number of lawns Ed mow, that is x so that the amount Ed has will be more than the amount he needs to buy the video game.
This can be shown as the equation:
Total amount Ed has > Cost of the video game,
or, 135 + 9x > 250.
Thus, the required equation is <u>135 + 9x > 250</u>.
