Benny is 12 years old. He is currently 200% of his sisters age. What percent of Benny's age will his sisters age be in 4 years?
CaHeK987 [17]
If Benny is 12 right now, that means that he is twice his sisters age because he is 200% of or 2 times his sister's age. His sister right now is 6 years old then. 
After 4 years, Benny will be 16 (add 4 to 12) and his sister will be 10. 
To find the percentage,divide his age by his sister's age and make it a percentage.
16/10=1.6=160%
Hope this helps.

If y = 7x − 5, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
LenaWriter [7]

Given equation is y =7x - 5.

Let's plug in the values of x's to get their corresponding values of y's.

Let's plug in x = -5. So,

y = 7( -5) - 5 = -35 - 5 = -40

So, the first order pair is (-5, -40)

Hence, the first choice is not correct.

For x = 2, y = 7 (2) - 5 = 14 - 5 = 9.

Second order pair is (2, 9). So, second choice is also not correct.

Now for x = 0, y = 7(0) - 5 = - 5.

So, the third order pair is (0, -5).

Let's plug in x = -3 to check the third order pair list as we have already got two order pair (0, -5) and (2, 9) from that list.

For x = -3, y = 7(-3) - 5 = - 21 - 5 = -26.

Hence the correct choice is {(0, −5), (2, 9), (−3, −26)}.

= 3 ×6

= 18

There were 15 adult dogs in the park on Tuesday
