Answer:

81.11 in decimal

81 1/9 in fraction

Step-by-step explanation:

Let the number be x

1.9 time a number is equal to 1.9x

1.7 plus 1.9 times a number is equal to 1.7 + 1.9x

Now given that

1.7 plus 1.9 times a number equals the sum of the number and 74.7

mathematically we have relation equation as

1.7 + 1.9x = x + 74.7

subtracting 1.7 from both side

1.7 + 1.9x  - 1.7 = x + 74.7 - 1.7

=> 1.9x = x + 73

subtracting x from both side

1.9x - x = x + 73 - x

0.9x = 73

dividing both side by 0.9

0.9x/0.9 = 73/0.9

x = 81.11 or 81 1/9

Thus, the number is

81.11 in decimal

81 1/9 in fraction

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. 2x+3y=6
sweet-ann [11.9K]

Answer:

x-intercept: (3, 0)

y-intercept: (0, 2)

Step-by-step explanation:

For a function like:

y = f(x)

The x-intercept is the value of x when y = 0

the y-intercept is the value of y when x = 0

Also remember that an ordered pair is written as (x, y).

In this case we have the equation:

2*x + 3*y = 6

For the x-intercept, we just replace y by zero in the equation, then we get:

2*x + 3*0 = 6

Solving this for x, we get:

2*x = 6

x = 6/2 = 3

Then in this case, the ordered pair for the x-intercept is (3, 0)

For the y-intercept, we just need to replace x by zero in the equation:

2*0 + 3*y = 6

Solving this for y, we get:

3*y = 6

y = 6/3 = 2

Then the ordered pair for the y-intercept is (0, 2)

The formula for volume is to multiply the length, width, and height.

l x w x h

2 x 5 x 3 = 30

So there is 30 ft of dirt in the hole.

brilliants [131]
Mrs Carson gives the better deal, this is becuase when i set up an inequality 48/6 and 67.50/9, i divided 48 by 2 then added 24 to 48 so i could get them both so i can see what they give, so Mrs Carson gives 72 dollars every 9 hours and thats better than 67.50.
