James and Michael are the partners in a local business. They needed $480,000 to start the
larisa [96]

Answer:

James invested $160,000

Step-by-step explanation:

- In total, they needed $480,000 to start the business

- 1:2 ratio means one of them payed double the amount than the other

so the expression would be,

2x + x = 480,000

Let x represent how much they each need to invest

the expression can be simplified to,

3x = 480,000

now you need to get x alone, this would be done be dividing both sides by 3

\frac{3x}{3} = \frac{480,000}{3}\\x = 160,000

James invest $160,000

Michael invest $160,000 x 2 = $320,000

and if you add them together, you get the total amount

$320,000 + $160,000 = $480,000

Let me know if you have any questions !

The points (x, 3) and (-2, 2) have a slope of 1. What is the x-coordinate of the point<br> (x, 3)?
Naya [18.7K]

Answer:

(-1,3)

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

1 = (2-3)/(-2-x)

Multiply each side by (-2-x)

(-2-x) = -1

Multiply by -1

2+x = 1

Subtract 2 from each side

2+x-2 = 1-2

x = -1
