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.
Answers
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.

The product of prime polynomials [tex]\rm 3x(x-3)(x^2+3x+9)[/tex] is equivalent to
[tex]\rm 3x^4-81x[/tex].
It is given that the polynomial [tex]\rm 3x^4-81x[/tex].
The product of prime polynomials is equivalent to the above polynomial.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have:
[tex]\rm 3x^4-81x\\\rm 3x(x^3-27)\\\rm 3x(x^3-3^3)\\\rm 3x(x-3)(x^2+3x+3^2) \\\\ We \ know \ that \ a^3-b^3=(a-b)(a^2+ab+b^2)\\3x(x-3)(x^2+3x+9)\\[/tex]

What is the value of x in the equation 8x – 2y = 48, when y = 4?.
Answers
Step-by-step explanation:
Substitute the value of y into the equation;
[tex]8x-2(4)=48[/tex]
Find the value of x.
Multiply;
[tex]8x-8=48[/tex]
Add 8 to each side;
[tex]8x=56[/tex]
Divide each side by 8;
[tex]x=7[/tex]
Answer:
x = 7
Step-by-step explanation:
Given:
y = 4Step-1: Substitute the y-variable in the equation (8x – 2y = 48)
⇒ 8x - 2y = 48⇒ 8x - 2(4) = 48Step-2: Simplify the L.H.S
⇒ 8x - 2(4) = 48⇒ 8x - 8 = 48Step-3: Add 8 both sides
⇒ 8x - 8 = 48⇒ 8x - 8 + 8 = 48 + 8⇒ 8x = 56Step-4: Divide 8 both sides
⇒ 8x = 56⇒ 8x/8 = 56/8⇒ x = 7An elephant weighs 8.8 x 103 kg. A small dog weighs 4 kg. How many

Use the circle to solve for the missing measures. Assume lines that appear tangent are tangent. Do NOT round any answers.
Answers
The given circle having two external tangents, according to circle
theorem, have the following values;
r = 3m∠1 = 82°m∠2 = 49°x = 82°How can the radial length and angles be found?r² + 1.6² = (0.4 + r)²
(0.4 + r)² - (r² + 1.6²) = 0
0.8·r - 2.4 = 0
0.8·r = 2.4
r = 2.4 ÷ 0.8 = 3
r = 3y = 49°
From the two tangent angle theorem, we have;
m∠1 = ((82 + 98 + 82) - (360 - ((82 + 98 + 82)))) ÷ 2 = 82
m∠1 = 82°According to circle theorems, angle at the center is twice angle
subtended at the circumference.
m∠2 = (360 - (82 + 98 + 82)) ÷ 2 = 49°
m∠2 = 49°The length of the chord subtended by the arc x is equal to the length of
the chord subtended by 89°, which gives;

Explain how you would go about graphing this equation? What would be your first step and how would you go from there? Y=4x+6 *
Answers
Step-by-step explanation:
First I would look at the y intercept. In a linear equation, y = mx + b, b is the y-intercept and m is the slope. This means that (0,6) is a point on the line since at a y-intercept, the x value is 0. First you should plot this point.
Next, the slope is 4, meaning that for every 1 unit to the right, the line rises 4 units. You can count 1 to the right and 4 up from the y-intercept, which gives you (1,10), a second point on the line. After this, you can connect the two points and there you go, you have a graph!

108/4 = πr³
27= πr^3
27/π =r³
r=
[tex] \sqrt[3]{27 \div \pi} [/tex]
r= 2.048in
round off to 2.05in
PROOF
V = 4÷3 x πr³
V= 4/3 x π(2.05)³
V=4/3 x π8.6
V=4×π×8.6/3
V=108/3
V=36in³

Bridgette has 25 pairs of black socks, 15 pairs of white socks, and 20 pairs of colorful socks. What is the ratio of colorful socks to total socks?
help?!
could you please explain to?!
Answers
Answer:
Step-by-step explanation:
So the total # of socks is 25 + 15+ 20, which equals 60.
theres ONLY 20 socks that are colorful, meaning that 20/60 are coloful.
20/60 simplified is 2/6, simply that even further its 1/3, 1/3 is a ration within itself. itll be 1:3
Answer:
1:3 (20:60)
Step-by-step explanation:
So the ratio of colorful socks to total socks is 20:60
This is how:
First write the number of colorful socks which is 20.
From the calculate the total number of socks( 20 + 25 + 15 = 60) which is 60.
Then put a colon and write 60
You need to write the number of colorful socks because that is what was mentioned first then the total number of socks because it was mentioned after the number of colorful socks.
So you can reduce 20:60 to its lowest term.
You write 20: 60 as a fraction [tex]\frac{20}{60}[/tex]
Then reduce [tex]\frac{20}{60}[/tex] to its lowest term which is [tex]\frac{1}{3}[/tex].
Then write [tex]\frac{1}{3}[/tex] as a ratio which is 1:3

explanation:
make equations from given information.
consider each minute as "n"equation 1 from plan A :
20 + 0.11(n)
equation 2 from plan B :
14 + 0.13(n)
Solve them simultaneously,
14 + 0.13(n) = 20 + 0.11(n)
0.13(n) - 0.11(n) = 20 - 14
0.02(n) = 6
n = 300
insert n = 300 in any of the equation, to find cost.
14 + 0.13(n)
14 + 0.13(300)
