Answer:
Step-by-step explanation:
<u>The first group consists of Petra and 4 friends, so the total number of members is 5, therefore the left side of equation should be:</u>
<u>The second group consists of 4 people, Valentina and 3 friends, therefore the right side of the equation should be</u>:
<u>Solving the equation to find the cost of a ticket for Petra's group:</u>
- 5(x + 5.5) = 4(1.5x + 4.75)
- 5x + 27.5 = 6x + 19
- 6x - 6x = 27.5 - 19
- x = 8.5
Cost of a ticket is $8.5

Answer:
False.
Step-by-step explanation:
The diagonals are at right angles ( because of the negative reciprocal slopes)
so it could be a square or a rhombus.
35+2x=20+2.50x
subtract 2.50x
35+0.50x=20
subtract 35 frim both sides
0.50x=-15
x=-30
Answer:
-6, -5, -1
Step-by-step explanation:
Based on the question, (x+6) is a factor of f(x).
With this, you can do the long division method of dividing f(x) with (x+6) {Refer to the image}.
You'll get x²+6x+5 as a result.
Factorise it and you'll get
x²+6x+5 = (x+1)(x+5)
Then let (x+1)(x+5) = 0, x = -1, -5
Zero's of f(x) are -6, -5 -1
