Answer:

x = 11.75

y = 11.5

Step-by-step explanation:

By Elimination Method:

   7x - 3y = 48    ---- (1)

-

<u>    2x + y = 35   ----</u>-   (2)

Multiply equation (1) by 2 and equation (2) by 7

   14x - 6y = 96

-

<u>    14x + 7y = 245      </u>

<u>      0   -13y = -149</u>

-13y = -149

y = -149/-13

y = 11.5

From equation (2); replace y with 12

2x + y = 35

2x + 11.5 = 35

2x = 35 - 11.5

2x = 23.5

x = 11.75

A rectangular pool has a length of 60 feet and a width of the square root of 18 feet.
Vsevolod [243]

a).  Area = (length) (width)

               = (60 ft) (√18 ft)

               =     (60 √18)  ft²

               =     60 √(9 · 2)   ft²

               =     60 (3) √2      ft²
 
               =   180 √2           ft²     (about  254.6 ft²)


b).  Volume  =  (length) (width) (height)

                    =  (60 ft) (√18   ft) (√10   ft)

                    =        60 √(180)         ft³

                    =        60  √(4 · 9 · 5)          ft³

                    =        60 (2) (3) √5             ft³    

                    =       360 √5         ft³        (about  805 ft³)

Productive use of machinery on a farm made it possible to decrease the number of tractors by 12. How many tractors does the farm
RideAnS [48]
The answer is 24. think of x as the original amount, and y as the new amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y, which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to subtract 12, which would help you get 24 as your final answer.

The total area of Canada is 9 984 670 km2. Calculate the side length of a square with the same area. Show your work.
Korolek [52]

Answer:

3159.853 km

Step-by-step explanation:

The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:

9984670 = (x)(x) which rearranges to 998470 = x^2

get the square root and you get:

x = 3159.853 km

I opened a grocery account at my bank with $250. Every week thereafter, I withdraw $90 from the account to pay for groceries. If
Ksenya-84 [330]

Answer:

y= -90x+250

Step-by-step explanation:

From the information given, the equation would be that the amount in the account would be equal to -90 that is the amount you withdraw from the account each week multiply for x that is the number of weeks plus $250 that is your initial balance:

y= -90x+250, where

y= amount in the account

x= number of weeks.
