John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.85. Write an equation to represent the problem. Find the cost of one large drink.
Answer:
Hm, okay.
Step-by-step explanation:
So, if the pizza cost $12.50, and the total money spent is $16.85, we must first subtract our money spent on pizza from the total amount spent.
$16.85 - $12.50 = $4.35
So, that means that John and his two friends spent $4.35 on 3 large drinks. But how do we figure out how much each individual drink cost?
We divide $4.35 by 3.
$4.35 / 3 = $1.45.
So, the amount of money spent on one large drink was $1.45.

Is a  circle not a parallelogram?
Answer:
A parrelogram is a shape with four sides (and something else I forgot). That doesn't matter because a circle doesn't even have sides! Therefore, it's not a parallelogram.
What is the solution for the equation
(10-5y|= 20
Answer:
y = -2
Step-by-step explanation:
To find the answer, use property of inequality:
10-5y=20
Undo the +10, so - 10 to the other side
so,
-5y= 10, or -5xY.
so divide by -5 from both sides:
10/-5=-2
so, the remain of the equation is:
y = -2
which is the answer

how do I find the surface area and volume of any shape?
Answer:
Step-by-step explanation:For any shape it’s always true that for volume
V
the surface area is: =2‾‾‾√3
for some constant depending on the shape. So to work out the surface area from the volume we just need to know the value of for the shape in the question.
For a cube for example we have that =6, assuming consistent units i.e.: unit 2 for area and unit 3
3
for volume.
More generally if we have formula for both volume and surface area in terms of a particular one dimensional measurement
d
of the shape then we can always write these formula in the form:
=13
=12
for constants constants 1 and 1
. Then we have:
=1‾‾‾√3
=1(1)2‾‾‾‾‾‾√3
=121‾‾‾√32‾‾‾√3
and therefore:
=121‾‾‾√3
For example for a sphere we have that that =42 and =433 and therefore:
=4(43)2‾‾‾‾‾‾√3
=36‾‾‾‾√3
So if a particular sphere has volume =8 then we can calculate its surface area to be:
=36‾‾‾‾√382‾‾√3=436‾‾‾‾√3 m2

Percy paid $24. 10 for a basketball. The price of the basketball was $22. 99. What was the sales tax rate?.
Answer:
$3.11
Step-by-step explanation:
you have to subtract 24.10 from 22.99
Answer:
First let's find the increase of the original price to it's new price;
24.10 - 22.99 = 1.11, there was a $1.11 increase.
Though, we need to find the percentage, using the formula:-
Changed price 100
____________ x _____ (100%)
Original amount 1
Our changed price was 1.11, and our original price was 22.99.
1.11 100
_____ x _____ = 4.828 which rounds to 4.83%
22.99 1

Devi’s dog weighs 4 times as much as her cat. Her dog also weighs 13 pounds more than the cat. How much does each pet weight?
Answer: The cat's weight is 4.33 pounds
• The dog's weight is 17.32 pounds.
Step-by-step explanation:
Let the weight of the cat be represented by a.
Devi’s dog weighs 4 times as much as her cat. This can be written as:
= 4 × a
= 4a
Her dog also weighs 13 pounds more than the cat. This can be written as:
= a + 13
We then equate both equations. This will be:
4a = a + 13
4a - a = 13
3a = 13
a = 13/3
a = 4.33 pounds
The cats weight is 4.33 pounds
Since the dog's weight = 4a = 4 × 4.33 = 17.32 pounds

Step-by-step explanation:
#5 - 7: Domain are the x-values and Range are the y-values.
5) Coordinates are: (-2, 3), (0, 3), (2, 3), (4, 3)
Domain: x = {3} Range: y = {-2, 0, 2, 4}
6) All points on the curve between -4 and 2 (x-values) & 3 and 6 (y-values). Endpoints are included.
Domain: -4 ≤ x ≤ 2 Range: 3 ≤ y ≤ 6
7) All points on the curve between 2 and 7 (x-values) & 1 and 6 (y-values). Endpoints are not included.
Domain: 2 < x < 7 Range: 1 < y < 6
#8 - 11: Choose points for x. Plug them into the equation to solve for y.
To graph the equation, plot the points and connect the dots.

Nicholas wrote the steps below to
simplify the fraction _
20
30. Melanie divided the numerator and
denominator of _
20
30 by 2 to write the fraction in the simplest form.
Explain and correct the error that each student made.
Answer:
He does not divide the numerator and the denominator by the same number. Nicholas divides 20 by 5 and 30 by 6. He ought to have divided 30 by 5 as well and then simplified.
P.S. Nicholas should have just divided both 20 and 30 by 10 to simplify in one step
Translate point (2, -1) three units to the left. Write the new coordinate as
an ordered pair. May someone help ASAP !
Answer:
(-1,-1)
Step-by-step explanation:
Because you're translating something 3 units to the left, then you are moving along the x-axis, so you will subtract 3 from 2.

PLEASE ANSWER I WILL MARK BRAINLIST
Answer:
8
Step-by-step explanation:
F(x)=2x^2+16x-7 in vertex form
f(x) = 2 ( x² + 8x ) - 7
= 2 [(x + 4)² - 4²] - 7
= 2 (x + 4)² - 32 - 7
= 2 (x + 4)² - 39
(x+4)² = x² + 2*x*4 + 4² = x² + 8x + 4²
it's why
x² + 8x = (x + 4)² - 4²
Answer:
y=2(x+4)^2−39
Step-by-step explanation:
Based on my calculation that´s the answer :-)

Put the following equation of a line into slope-intercept form, simplifying all
fractions.
6x + 4y = 8
Answer:
[tex]y=-\frac{3}{2}+2[/tex]
Step-by-step explanation:
First subtract 6 from both sides:
[tex]6x+4y=8[/tex]
-6 -6
New equation becomes:
[tex]4y-6=8[/tex]
Divide all by 4:
4 -6 8
--- --- ---
4 4 4
[tex]y=-\frac{3}{2}+2[/tex]
Hence, the final answer is [tex]y=-\frac{3}{2}+2[/tex]
