Please, help me with this!

Answer:

A x ≤ 17/2

Step-by-step explanation:

(2x+7) /-4 ≥ -6

Multiply each side by -4, remembering to flip the inequality

(2x+7) /-4 *-4 ≤ -6*-4

2x+7 ≤ 24

Subtract 7 from each side

2x+7-7 ≤ 24-7

2x ≤ 17

Divide each side by 2

2x/2 ≤ 17/2

x ≤ 17/2

A jewelry store has 311.75 ounces of 14-carat gold in stock.

WARRIOR [948]

Answer:

$\boxed{\text{(a) 86 necklaces; (b) \$2220}}$

Step-by-step explanation:

(a) Number of necklaces

3⁵/₈ = 3.625

$\text{No. of necklaces} = 311.75\text{ oz} \times \dfrac{\text{1 necklace}}{3.625\text{ oz}} = \textbf{ 86 necklaces}\\\\\text{You can make } \boxed{\textbf{86 necklaces}} \text{ from 311.75 oz of 14K gold}$

(b) Value of gold in each necklace

There are 3.625 oz of 14K gold in each necklace. Pure gold is 24K.

$\text{Mass of pure gold} = \text{3.625 oz} \times \dfrac{\text{14K}}{\text{24K}} = \text{2.1146 oz}$

Pure 24K gold is worth $1050/oz.

$\text{Value of pure gold} = \text{2.1146 oz} \times \dfrac{\text{\$1050}}{\text{1 oz}} = \textbf{\$2220}\\\\\text{The value of the gold in each necklace is } \boxed{\textbf{\$2220}}$

The difference of nine times a number and the quotient of 6 and the same number

SOVA2 [1]

Answer:

3/4

Step-by-step explanation:

Let the number = x

Nine times the number = 9x

Hence, 9x - 6 = x

9x - 6 = x

9x - x = 6

8x = 6

∴ x = 6/8 = 3/4
