Answer:

A.) k=0.5

Step-by-step explanation:

If we use the formula given: y=kx, we can plug in values.

0.5=k(1)

0.5=(0.5)(1)

0.5=0.5

We know that to get from 1 to 0.5, we need to divide by two, or multiple by 1/2. 1/2 in decimal form is 0.5

Solve for x???????????

expeople1 [14]

Answer:

$x=9$

Step-by-step explanation:

For this you just have to make an equation and in order to do that you have to know that all these angles will equal 180°. Now we can write it out.

$3x-4+13x+2+5x-7=180$

Now we combine like terms:

$21x-9=180$

Add the 9 on both sides:

$21x=189$

Divide the 21 on both sides:

$x=9$
