Hello there!

Reminder: Your question will be removed if you have more than 3 questions in the post.

1:

3 ( -3 + 7x ) ≤ - 93

-9  + 21x ≤ 93

93 + 9 = 102

102/21 = 4.857

4.857 --> 4.86

4.86  ≤  x

2:

-6 ( 1 + 8x ) ≥ 138

-6 - 48x ≥ 138

138 + 6 = 144

144/-48 = -3

x ≥ -3

3:

7 ( 6x -4 ) ≥ 6x - 28

42x - 28 ≥ 6x - 28

36x - 28 ≥ -28

-28 + 28 = 0

36x ≥ 0

4:

86 ≤ -4 ( 1-5x) -2x

86 ≤ -4 + 20x - 2x

86 ≤ -4 + 18x

90 ≤ 18x

90/18 = 5

x ≤ 5

Serga [27]
If its meaning making a profit after the $300 then:
540+300=840
840/24= 33.60
They would charge $33.60 per necklace.

If you were meaning a profit of $540 total then:
540/24=22.5
They would charge $22.50 per necklace.

HELP ME PLEASE [WILL GIVE BRAINLIEST TO BEST ANSWER WITH BEST EXPLAINATION]

Hi there!

\large\boxed{\text{33 in}^2}

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.

Rectangles:

A = l × w

A = 2.75 × 4 = 11 in²

Solve for the other rectangle's length by subtracting from the total:

12 - 2 - 3 - 4 = 3

A = 3 × 3 = 9 in²

Total rectangle area: 11 + 9 = 20 in²

Trapezoid:

A = 1/2(b1 + b2)h

A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²

Triangle:

A = 1/2(bh)

A = 1/2(2.5 · 2) = 2.5 in²

Add up all of the areas:

20 + 10.5 + 2.5 = 33 in²
