Which is better value for money: 2 pizzas for
£12 or 4 pizzas for £28?
For the first one, each pizza is $6
For the second one, each pizza is $7
The first one is the answer
Answer:
2 pizzas for £12.
Step-by-step explanation:
[tex]\frac{2}{12}: \frac{1}{y}[/tex]
y · 2 = 12 · 1
2y = 12
2y ÷ 2 = 12 ÷ 2
y = 6
£6 for 1 at the price of 2 for £12.
[tex]\frac{4}{28}: \frac{1}{y}[/tex]
y · 4 = 28 · 1
4y = 28
4y ÷ 4 = 28 ÷ 4
y = 7
£7 for 1 at the price of 4 for £28.

Step-by-step explanation:
Solve w = x + for y.
Reply really fast and give like the work for it too please
Answer:
see below
Step-by-step explanation:
w = x+y/z
Subtract x from each side
w-x = x+y/z -x
w-x = y/z
Multiply each side by z
(w-x) *z = y/z*z
(w-x) *z = y
You can distribute the z if desired
wz -xz = y
Answer:
y = z(w - x)
Step-by-step explanation:
w = x + y/z
Subtract x from both sides
w - x = y/z
Multiply both sides by z
z(w - x) = y
Flip
y = z(w - x)

Find the zeros of the function. Enter the solutions from least to greatest.
f(x) = (x + 2)^2 – 64
lesser x =
greater x =
Answer:
6 & -10
Step-by-step explanation:
Given :
f(x) = (x+2)² - 64And we need to find the Zeroes of the given function .For that equate the polynomial with 0 , we have ,
[tex]:\implies[/tex] f(x) = 0
[tex]:\implies[/tex] ( x + 2 )² - 64 = 0
[tex]:\implies[/tex] ( x + 2)² = 64
[tex]:\implies[/tex] ( x + 2 ) = √64
[tex]:\implies[/tex] ( x + 2) = ± 8
[tex]:\implies[/tex] x = -2 ±8
[tex]:\implies[/tex] x = -10 , 6
Hence the value of 6 and -10 .

Which shows a pair of similar circles ?
Answer:
d) I, II and III.
Step-by-step explanation:
Two circles are similar when the two circles have different or equal radii. In case I, we have similar circles that are congruent and non-concentric, since their radii are equal. In case II, we find two similar circles which are secant to each other. Lastly, the case III represents two similar circles which are concentric.
Therefore, I, II and III show pairs of similar circles.

Answer:
1/4
Step-by-step explanation:
there are 2 multiples of 3, 3 and 6
2/8=1/4
Answer: 1/4 chance (second option on the screen)
Step-by-step explanation:
dw probability is confusing to a lot of ppl
so if you count the sections theres 8 in all
to see the probability we must find how many times we will get a positive outcome, or what we want (the multiple of 3)
lets see how many multiples of 3 there are
theres 3 and 6
thats two out of the eight possible outcomes at any moment u spin the spinner
so thats an 2/8 chance
you can simplify that fraction to a 1/4 chance, so its the second option on your screen

greater x =
Answer:
lesser x = -6
greater x = 12
Step-by-step explanation:
(x - 3)^2 - 81 = 0

x - 3 = +/- 9
x - 3 = 9 or x - 3 = -9
x = 12 or x = -6
which does NOT represent a function? ill give brainliest
Answer:
C
Step-by-step explanation:
C is not a function because 5 has two y values
Answer:
Option C is NOT a function.
Step-by-step explanation:
For these functions we will use subtraction as our example. With option A the pattern is: -8, -7, -6, -5. Therefore option A is a function. With option C the pattern is: 3, 3, 3, 2. Therefore this is not a function. With option B the pattern is 0, 0, 0, 0. Therefore this is a function. With option D the pattern is: -6, -2, 2, 6. Therefore this is a function.
