Answer:

y is 8/5 when x = -4.

Step-by-step explanation:

If the value of "Y" varies directly with "X", we can write y = kx, where k is the constant of proportionality.

If "y=-8,when x=20," then we can find k:    -8 = 20k, or k = -2/5.

Then y = (-2/5)x.

If x = -4, then y = (-2/5)(-4) = 8/5

y is 8/5 when x = -4.

Jim is a radio ad salesperson. He is paid 17 percent for every ad he sells. He sold an ad today for $2,000.00. What is his commi
stiks02 [169]

Answer:

$340

Step-by-step explanation:

Given:

Jim is paid 17% for every ad he sells.

He sold an ad today for $2000

Now we have to find the commission.

The commission rate is 17%

If he sells $100, then he gets $17 as commission.

To find the commission on sale ad of $2000, we have to multiply 2000 by 17%

17% of 2000

= \frac{17}{100} *2000

We can simplify 2000 by 100, we get

= 17*20

Commission = $340

He gets $340 as commission for the ad sale of $2000.

The sum of the angles in a triangle is 180, so the equation will be :
2k+k+45= 180
add similar variables
3k+45=180
3k=135 (divide each side by 3)
k= 45
So 2k equals= 90
k=25
This is right angle triangle for your info!
