Barry and Lenora were each given the same pair of numbers. Barry's description of the two numbers was: The larger number is 30 more than the smaller number, s. Lenora's description of
the two numbers was: Twice the smaller number decreased by 10 is the larger number.
Which equation represents this situation?
A 30s - 2s - 10
30+S - 2s +10
CS-30-10-2s
D 30+ 5 = 2s - 10
30+5=2st 10

30 + s = 2s - 10

Step-by-step explanation:

Have a good day!

This is the answer because a number more means +

and decreased means -

times is when a number is next to another number Example: {1(2) = 2}/ 1 x 2 = 2

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
