Answer:

-7 > x

Step-by-step explanation:

first we expand the brackets so it will be -3x -6>-69-12x

then we can convert the > to = so it will be :

-3x -6=-69-12x

we can now try to solve the equation for x so :

-3x -6= -69-12x

-6 = -69-9x

63 =-9x

7 = -x

-7 = x

we can then change the symbols back so it will be:

-7 > x

Find out how many feet will the bike move after 15 rotations

Let

x ----> the distance in feet

Kevin is 3 years older than daniel. Two years ago, Kevin was 4 times as old as Daniel. Let k be Kevin’s age and let d be Daniels

bezimeni [28]

Answer:

Daniel (now) is 3 years old, (2 years ago) is 1 year old.

Kevin (now) is 6 years old, (2 years ago) is 4 years old.

Step-by-step explanation:

Now:

-Kevin: k = d + 3

-Daniel: d

2 years ago:

-Kevin: k - 2 = 4(d - 2)

-Daniel: d - 2

We have the equation:

(k - 2) + 2 = k

4(d - 2) + 2 = d + 3

4d - 8 + 2 = d + 3

3d - 6 = 3

3d = 9

d = 3

k = d + 3 = 3 + 3 = 6

Hello!! Actually I got A x = 2, y = 12.

Whenever you plug them in, 2(2) + 3(12) = 40

-2(2) + 2(12) = 20

It worked for me this way, I hope this is the right answer. Have a great day!
