A proportional relationship is formed when y = 16 and x = 4. What is the value of y when x = 2? The relationship is assumed to be directly.

y = 8

Step-by-step explanation:

Given the relationship is direct then the equation relating the quantities is

y = kx ← k is the constant of proportion

To find k use the condition when y = 16, x = 4, then

16 = 4k ( divide both sides by 4 )

4 = k

y = 4x ← equation of proportion

When x = 2, then

y = 4 × 2 = 8

step-by-step explanation:

no

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
