The length of the top of a table is 55 m greater than the width. the area is 8484 msquared2. find the dimensions of the table.
Oksana_A [137]
You have to do similar calculations you use in algebra. This is how I get the answer;
First I draw out the algebraic formula 55m • X = 8,484 m (meters) 2 (squared). Then I switch the sign from multiplication to division and switch put numbers 55 and 8,484 in different places and change it to your new formula 8,484/(divided) 55 =X. Then you do the math of 8,484 divided by 55 and get an answer of 154.254545. But you can just leave it at the first 2 digits on the right side of the decimal by rounding 4 down and leaving it at an answer of ~~(<This is your answer after being put together with these tips (you always right your final answer using your formula and plugging in the number that we got from dividing 8,484 by 55;

Final answer ( if they wanted it included in a formula); 8,484/55=X let X=~~154.25

Final answer (if they wanted it as one final number as you answer); ~~154.25

*Hope these tips helped you with this mathematical problem :)

I just need to find out the last question that is in red. I don't know how to find the year when the median house values will be
Ganezh [65]

Answer:

1924.3

Step-by-step explanation:

Ok

You need to write an expression for the change in value

the change is linear, so you will get a line equation y = mx + b

y-axys : value

x-axys : years

New Hampshire:

Slope = \frac{133300-37600}{2000-1950} = 1914

the y-intercept will be 37600 because you can assume that 1950 = 0, and 2000 = 50

y = 1914*x + 37600

Massachussets:

Slope = \frac{185700-55400}{2000-1950} = 2606

Same as above, the y-intercept is 55400

y = 2606*x + 55400

Now you need to equal the value for both and find the year "x"

1914x + 37600 = 2606x + 55400

- 692x = 17800

x = -25.7

Since i considered x = 0 to be 1950; the actual year is 1950 - 25.7 = 1924.3
