Answer:

(y+z=6)*-3

Step-by-step explanation:

using this would make the top equation or (y+z=6) turn negative and would be this [-3y-3z=-18) using the distributive property. Since the bottom equation has a positive 3y. The -3y from the top equation and 3y from the bottom ones cancel out leaving you with z=-17 when combining like terms.

Answer:

c is the answer since you are trying to make the ys number (-/+) of the value the other y contains

Answer:

Angle 1 - 51

Angle 2 - 39

Angle 3 - 90

Angle 4 - 51

Angle 5 - 17

Angle 6 - 129

Step-by-step explanation:

Angle 1 = 180 - 90 - 39 = 51

Angle 2 = 90 - Angle 2 (51) = 39

Angle 3 = 90

Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51

Angle 5 = 180- 90 - 34 -39 = 17

Angle 6 = 180 - Angle 4 (51) = 129

-18= 5-(6k - 19) i have the answer but i need help on how to get the answer 7?
insens350 [35]

Answer:

k = 7

Step-by-step explanation:

Step 1: Write equation

-18 = 5 - (6k - 19)

Step 2: Solve for <em>k</em>

<u>Distribute negative:</u> -18 = 5 - 6k + 19

<u>Combine like terms:</u> -18 = -6k + 24

<u>Subtract 24 on both sides:</u> -42 = -6k

<u>Divide both sides by -6:</u> k = 7

Step 3: Check

<em>Plug in k to verify it's a solution.</em>

-18 = 5 - (6(7) - 19)

-18 = 5 - (42 - 19)

-18 = 5 - 23

-18 = -18

The total arrangements Jocelyn can make is 239573160 if Jocelyn is making flower arrangements for a party and has a choice of 9 carnations, 12 daffodils, and 12 tulips.

<h3>What are permutation and combination?</h3>

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

It is given that:

Jocelyn is making flower arrangements for a party and has a choice of 9 carnations, 12 daffodils, and 12 tulips.

Arrangements for carnations = P(9, 6) = 60480

Arrangements for daffodils = P(12, 4) = 11880

Arrangements for tulips = P(12, 4) = 239500800

Total arrangements = 60480 + 11880 + 239500800 = 239573160

Thus, the total arrangements Jocelyn can make is 239573160 if Jocelyn is making flower arrangements for a party and has a choice of 9 carnations, 12 daffodils, and 12 tulips.
