Find X and Y such that X + Y = 500 and the difference between X and Y is 100.

zavuch27 [327]

Answer:

X=300, Y=200

Step-by-step explanation:

If: X+Y=500,

Then Y = 500-X

IF X-Y=100,

Then:

X-(500-X)=100,

X-500+X=100,

2X-500=100,

2X=100+500

2X=600

X=300.

So,

X+Y=500,

300+Y=500

Y=500-300

Y=200

So:

X=300, Y=200

Does anyone know this??

Mnenie [13.5K]

Answer: 21

Step-by-step explanation: To solve this problem, we can first set up a proportion because we know that 3 is to 7 as 9 is to x.

So we have $\frac{3}{7} = \frac{9}{x}$ .

Now, we can use cross products to find the missing value.

So we have 3 time x which is 3x and 7 times 9 which is 63.

Rewriting our equation, we have 3x = 63.

Dividing both sides by 3, we find that <em>x = 21</em>.

So, <em>x = 21</em>.

The red arrows in the middle mean that they are parallel so the slopes are the same.
