Answer:

−7x+15

Step-by-step explanation:

Step 1: Distribute the negative sign,

=2x+6+ − 1(9x−9)

=2x+6+ −1(9x)+(−1)(−9)

=2x+6+ −9x+9

Combine Like Terms:

=2x+6+ −9x+9

=(2x+−9x)+(6+9)

=−7x+15

Solve for b. -t = 9(t - 10) (WILL GIVE BRAINLIEST)

coldgirl [10]

Answer:

Do you mean solve for t?

If you do, the answer is 9.

Step-by-step explanation:

If we expand the equation out, we get:

-t = 9t - 90

If we move the -90 over to the left side and the -t to the right side, we get:

90 = 10t

Dividing both sides by 9, we get:

t = 9

Let’s think about another type of scenario. What if you were told that a bracelet requires 10 beads and 10 minutes to make while

Georgia [21]

Answer:

$425

Step-by-step explanation:

Let x represent the number of bracelets made and let y represent the number of necklace made.

Since the craftsman has 1000 beads to work with, hence:

10x + 20y ≤ 1000 (1)

Also, the craftsman has 1600 minutes, hence:

10x + 40y ≤ 1600 (2)

From ploting equations 1 and 2 on the geogebra online graphing, we can see that the solution to the problem is (40, 30).

Since the bracelet costs $5 and a necklace costs $7.50, hence the maximum revenue is:

Revenue = 5x + 7.5y = 5(40) + 7.5(30) = $425
