A house painter used the equation y = 6.2x to determine the number of gallons of paint, y, needed to paint a number of houses, x
lesya [120]

Answer:

(2,12.4)  , (5,31),  (8,49.6)

Step-by-step explanation:

To Solve this problem, let substitute value  of x from given table into equation y = 6.2x and determine value of y .

For x = 2

y = 6.2x

=> y = 6.2*2 = 12.4

__________________________________________

For x = 5

y = 6.2*5

=> y = 31

__________________________________________

For x = 8

y = 6.2*8

=> y = 49.6

__________________________________________

Thus, second table represent the equation.

(2,12.4)  , (5,31),  (8,49.6)

If a+1/a=3 then find the value of a-1/a​
kenny6666 [7]

Answer:

  • √5

Step-by-step explanation:

<u>Given a + 1/a = 3, find its square:</u>

  • a² + 2a*1/a + 1/a² = 9
  • a² + 1/a² = 9 - 2 = 7

<u>Now find the square of (a - 1/a):</u>

  • a² - 2a*1/a + 1/a² =
  • a² + 1/a² - 2

<u>Substitute the value from the first square:</u>

  • 7 - 2 = 5

<u>Since (a - 1/a)² = 5, its square root is:</u>

  • a - 1/a = √5

The jars of the paint in the art room have different amounts of paint.the green paint jar is 4/8 full.the purple paint jar is 4/
Vaselesa [24]
The green jar is 4/8 full
the purple is 4/6 full
the less full jar is 4/6 because 4/6 = 2/3 and 4/8=1/2
2/3 is bigger than 1/2
so the less full jar is the one having the green paint which has 4/8 of paint
