Answer:

x=4/11

y=9 1/11

Step-by-step explanation:

y = 3x+8

5x + 2y =20

5x + 2 (3x+8) =20  .. substitute y

5x + 6x +16 = 20

11x = 20-16 = 4

x = 4/11

Y = 3*4/11 + 8 = 1 1/11 + 8 = 9 1/11

9x − 3

Step-by-step explanation:

−9x + 3 = −1(−9x + 3) Multiply the expression by −1.

−1(−9x) + −1(3) Distributive Property

9x − 3 Simplify.

The additive inverse of the given expression is 9x-3​.

The given expression is -9x+3.

The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.

The additive inverse of the expression is -(expression).

Now, -(-9x+3)

= 9x-3

Therefore, the additive inverse of the given expression is 9x-3​.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Crafter's Warehouse sells 3 yards of gray tulle for $5.63. They sell 6 feet of black tulle for $3.58.

The units rate price of gray tulle will be given as,

⇒ $5.63 / 3

⇒ $1.88 per yard

The units rate price of black tulle will be given as,

⇒ $3.58 / 6

⇒ $0.60 per yard

The black tulle has a better price because its cost is less. Then the correct option is C.
