The answer is y=3

To show my work here.

1. regroup terms ( y + 3 = 9 - y)

2. subtract 3 from both sides ( y = 9 - y - 3)

3. simplify 9 - y - 3 to 6 - y ( y = 6 - y)

4. add y to both sides ( y + y = 6)

5. simplify y + y to 2y (2y = 6)

6. divide both sides by 2 ( y = 6/2)

7. simplify 6/2 to 3 ( finally y = 3)

Hope this helps, and if it does don't forget to mark as brainliest.

Start with your lowest numbers, 3 bracelets have 24 beads. The easiest way to find your answer is to find out how many beads are on 1 bracelet. So 24/3 will give us that answer. 24/3=8. and then multiply 7 by 8 to get 56. then check your answer to make sure it fits.
3 x 8 = 24
5 x 8 = 40
7 x 8 = 56
9 x 8 = 72

What is an equation of the line that passes through the point (−2,−3) and is parallel to the line 4x-y=14
liraira [26]

Answer:

4x - y = -5

Step-by-step explanation:

The equation of a new line which is parallel to old line 4x - y = 14 looks exactly the same as that of the old line EXCEPT that we replace the constant, 14, with C and find C for the line that passes through (-2, -3).

4x - y = 14     becomes     4x - y =  C

Now substitutte -2 for x, -3 for y and calculate C:

4(-2) - (-3) = C, or

-8 + 3 = C = - 5

Thus, the new equation is 4x - y = -5
