Y should also be halved.

For example, if x=4 and y=2, x=2y.
If x is halved for x=2, you get 2=2y, or y=1, which is still one half of x, so the proportion remains the same.

Answer:

y is also halved

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

If x increases then y increases

If x decreases then y decreases

therefore

If x is halved then y is also halved

Answer:

arc HK = 60

Step-by-step explanation:

angle HLK is an inscribed angle and arc HK is the arc it intercepts

an inscribed angle is equal to half the measure of the arc it intercepts

this can also be said as the intercepted arc is equal to twice the measure of the inscribed angle

Hence arc HK = 30 * 2 = 60

Ann and Betty together have $60. Ann has $9 more than twice Betty's amount. How much money does each have?
Ymorist [56]
First and mainly keep that 9 one side,
There are 2 people involved Ann and Betty, Then divide the TOTAL AMOUNT BY THE NUMBER OF PEOPLE.
· Then it will look like $60÷2= $30 per person.
In this case everyone has equal amount of money, but the question say Ann has $9 more than Betty's. so, Ann≈ $30 +$9= $39.
                                                       Betty≈ $30-$9= $21
         Because loses money because Ann has more,                        
                                      TOTAL=Ann+Betty
                                       $60= $39+$21
