Assume y varies directly as x. if y=8 when x=42; find y when x=126
Soloha48 [4]
Varies directly basically means a multiple of

y = kx

where "k" is the constant of variation. You must solve for this first using the given information.

8 = 42k
8/42 = k
0.19= k

Equation: y = 0.19x
when x = 126
y = 0.19(126)
y = 24

12. I don’t know how to do it
Nostrana [21]

Answer:

BC = 50

Step-by-step explanation:

I believe what I'm doing is correct but to be completely honest with you, I haven't done this in a while lol

Okay so...

You would do

1. 6y-16 = 4y+6

You would subtract 4 from 6...

2. 2y-16 = 6

You would then add 16 to 6...

3. 2y = 22

Then, divide 2 from 22...

4. y = 11

Substitute into BC...

5. 6 (11) - 16 = 66 - 16 = 50

Then, you get your final answer...

6. BC = 50

I hope it's right. Good luck ^^

Which pair of numbers have a greatest common factor of 7?
ella [17]
<span>The GCF is the number that is a factor of both (or all) of the numbers of a given set and which is the biggest factor of this kind (often the smaller number of the two)

7 and 14 have a greatest common factor of 7.

 28 and 7 also have a GCF of 7, so the first two responses fit.

21 and 3 have a GCF of 3, so that isn't correct.

7 and 1 have a GCF of 1, so that's incorrect as well.</span>
