Answers
Answer:
A. 38.5
Step-by-step explanation:
Since the angles <XWZ and <XYZ are congruent, <ZYW is just half of <XYZ, so you would just divide 77 in half to get your answer. It's a rhombus, so it works similarly to a square. If one side is congruent, the other is too.

Lateena solved the equation below. Is her solution correct? Explain why or why not.
Answers
Answer:
it isn't correct
[tex]x {}^{2} - 6x - 7 = 0 \\ d = 36 + 28 = 64 \\ x1 = \frac{6 - 8}{2} = - 1 \\ x2 = \frac{6 + 8}{2} = 7[/tex]
Answer:
her solution isn't correct .
because she had done a slight mistake in her calculation.
i.e.
[tex]\sqrt{16}=4 \:\:not \:\:16[/tex]
Step-by-step explanation:
solution given:
x²-6x-7=0
making it a perfect square
we must make it on the form of (a+b)²or(a-b)²
so
x²-2*3*x+3²-3²-7=0
(x-3)²-9-7=0
(x-3)²-16=0
adding 16 on both aide
(x-3)²=16
doing square root on both side
[tex]\sqrt{(x-3)²}=\sqrt{16}[/tex]
x-3=±4
taking positive
x-3=4
adding 3 on both side
x=7
and.
taking negative
x-3=-4
adding 3 on both side
x=-4+3
x=-1
x=-1 or 7

This year, the campground doubled the cost per hour for renting a kayak but kept the
insurance fee the same.
Which expression models the total cost for a guest to rent a kayak for x hours at the
campground this year?
A. 12 + 8x
B. 6 + 16x
C. 6 + 4x
D. 3 + 8x
Answers
Answer:
B.
Step-by-step explanation:
I had this question on a test and got it right
The expression models that shows the total cost for a guest to rent a kayak for x hours is 6 + 16x.
What is the model about?Note that in the question:
Last year = 6 + 8x.
Looking at the equation one can see that the premium is = 6
kayaks is known to be charging at 8
So we have to double the value which is:
8 x 2 = 16
So therefore, the equation will be:
16x + 6
Therefore, The expression models that shows the total cost for a guest to rent a kayak for x hours is 6 + 16x.

You are considering buying organic milk at the grocery store. A gallon of organic milk costs $1.00 more than a regular gallon of milk. Write an equation to represent the additional cost (C) of buying a gallon of organic mik over time (t) where x represents the cost of a gallon of regular milk
Answers
Answer:
C= $1t + x
Step-by-step explanation:
So, an organic gallon of milk is 1 dollar more then regular so the equation starts at $1 + x.
But then buying the organic milk over time is t so you add that to the one dollar since it applies to the organic milk. Now the equation is $1t + x.
But now, the expression we wrote is equal to C so, now the equation is C=$1t + x
