Answer:

  • 7 pink flowering plants

Step-by-step explanation:

  • Total number of plants = 15
  • Total cost = $96
  • Cost of pink flowering plant = $8
  • Cost of purple flowering plant = $5

<u>Let x and y be the number of plants bought. Then we have equations:</u>

  • 8x + 5y = 96
  • x + y = 15 ⇒ y = 15 - x

<u>Substituting y in the first equation:</u>

  • 8x + 5y = 96
  • 8x + 5(15 - x) = 96
  • 8x + 75 - 5x = 96
  • 3x = 96 - 75
  • 3x = 21
  • x = 7

Correct option is the second one

Braden and Jason, who are florists, purchased flower bouquets and vases at the same store. Braden bought 3 flower bouquets and 5
Sergeeva-Olga [200]
The price of a flower bouquet is $2.75 according to the information on the question above. This problem can be solved using two linear equations with two different variables based on the transaction. The first equation is 3x +5y= 25.75 and the second equation is 8x+2y=29 which can be simplified as y=14.5-4x. You can find the x by substituting the "y" variable on the first with the second equation resulting in "x =2.75" which is the price of the flower bouquet<span>.</span>

Circles A, B, and C overlap. The overlap of circles B and C is labeled x. Which statements are true about x? Select three option
Paladinen [302]

Answer:

(A)x ∈ B ⋃ C

(B)x ∈ B ∩ C

(C)x ∈ A ⋃ C

Step-by-step explanation:

A diagram has been created and attached for more understanding.

If the overlap of circles B and C is labeled x.

Then: x \in (B \cap C)

If x is contained in the intersection of B and C, it means that:

x \in B $ and x \in C.\\$Therefore:\\x \in B \cup C

Finally:

x \in C $ and x \notin A\\$x will be in the union of A and C\\Therefore, x \in A \cup C

The correct options are A, B and C.
