Answer:
B.) C(d)= 12d+42
Step-by-step explanation:
A flat fee means it is only paid once and doesn't increase or decrease.
The gigabytes of data fluctuate how much you pay the 12 dollar amount.
Meaning 12d represents the price of data and +42 shows the flat rate.
Overall giving us the equation C(d)= 12d+42.

if JK is tangent to circle L, find x
Answer:
if JK is tangent that means it creates 90° with X that is the ray of the circonference.
to find X first you have to find L and to do so you use the inverse of pythagorean theorem cause you have the hypotenouse :
sqr( 25^2-1^2) = 24.97
now divide by 2 and you have 12.49

Lila is making 1/4 of a recipe for a bake sale. The original recipe calls for 2/3 cups of sugar. How much sugar does Lila need to
complete her recipe?
Answer:
Step-by-step explanation:
1/4 of 2/3 is just (1/4) / (2/3) or (1/4)(3/2)
1/4 * 3/2= 3/8
She needs to use 3/8 of a cup
The sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed to complete her recipe.
What is fraction?A fraction is a percentage of a whole. This entire sentence could be referring to a single location or a collection of locations. The English word "fraction" originates from the Latin word "fraction," which means "to break." As the first society to comprehend fractions, the Egyptians used fractions to solve a number of mathematical problems, including the distribution of food and resources and the absence of a metal currency.
Given:
The sugar quantity in the original recipe = 2 / 3
If Lila is making 1 / 4 of a recipe, so she needs 1/ 4 of the total sugar in the recipe,
The sugar needed by Lila = 1 / 4 of 2 / 3
The sugar needed by Lila = 1 / 4 × 2 / 3,
The sugar needed by Lila = 1 / 6 of the total sugar needed in the recipe.
Therefore, the sugar needed by Lila to make 1 / 4 of a recipe is 1 / 6 of the total sugar needed in the recipe.

2. How many zeros does this parabola have?
write the following as
t = _____
p/q = q/t + 1
Answer:
t = 2q²/p
Step-by-step explanation:
subtract 1 from each side to get:
p/q - 1 = q/t
multiply each side by t/q to get:
(tp/q²) - 1 = 1
add 1 to each side to get:
tp/q² = 2
cross-multiply to get:
tp = 2q²
divide each side by p to get:
t = 2q²/p

Consider this exponential equation:
f(x) = 5(3)^x
Identify the following:
Domain
Range
Y-intercept
Step-by-step explanation:
F( x ) = 5 (3) ^ x
Y intercept
Let x = 0
f(0) = 5× 3 ^ 0
f(0 = 5 × 1
f(0) = 5
X intercept
let y = o
0 = 5 × 3 ^x
No x intercept/ zero
therefore
Vertical intercept (0; 5)

The difference of twice a number and five is three. Find the number
Answer:
The number is 4.
The step describe to solve the problem is: add five and then multiply by
Step-by-step explanation:
Let the number be x.
As per the given condition as:
The difference of twice a number and five is three.
"Twice a number" means
"difference of twice a number and five" means
therefore, the translation of the given word problem to an equation is:
Now, solve the equation :
Addition Property of equality states that you add the same number to both sides of an equation.
Add 5 to both sides of an equation we get;
2x-5+5=3+5
Simplify:
2x = 8
Multiplication property of equality states that you multiply the same number to both sides of an equation.
Multiply by both sides we get;
Simplify:
x = 4
The steps which describe to solve the problem is: add five and then multiply by
Therefore, the number x = 4

A group of 8 friends shared all the sports cards in 3 packages. Each package contained 1,400 sports cards. Each friend received the same number of sports cards.
How many sports cards did each friend receive?
Answer:
i think it is 525 cards.
Step-by-step explanation:
because 3 packages = 1400 sport cards
3 x 1400 = 4200
4200 divided by 8 = 525 cards.
What would y equal for this question
Answer:
12
Step-by-step explanation:
When looking at triangles it's always important to remember what the ratios are to parts of triangles. In the case of this triangle let's give the value 24 the variable of E. In every scenario in which Y is positioned above 24 or E, the answer is always E/2=y, or 24/2=y ---> 12.
y / 24 = 12 / 12 + 18
y / 24 = 12 / 30
y / 24 = 2 × 6 / 5 × 6
y / 24 = 2 / 5
y = 24 × 2 / 5
y = 48 / 5
y = 96 / 10
y = 9.6
A movie theater sells morning tickets (m) for $4 and regular tickets (e) for $6. During one week, the theater earned $6000. The theater sold 890 more regular tickets than morning tickets.
Write a system of liner equation to represent this situation. (Solve by using Systems by Substitution)
Answer:
Step-by-step explanation:
Answer:
m = 66 & e = 956
Step-by-step explanation:
Create your equations:
$4m + $6e = $6000
m + 890 = e
Substitute/solve for morning tickets:
$4m + $6e = $6000 <-- m + 890 = e
$4m + $6(m + 890) = $6000
$4m + $6m + $5340 = $6000
$10m = $6000 - $5340
m = $660/$10
m = 66 morning tickets
Solve for Regular tickets:
m + 890 = e <--- m = 66
66 + 890 = 956
e = 956 regular tickets
Double check work:
$4m + $6e = $6000
$4(66) + $6(956) = $6000

Below are two parallel lines with a third line intersecting them.
If 5x + y = 20 and 10x - 2y = 50 are two linear equations in two variables. Find the value of x and y.
x = 1, y = 1
x = 2, y = 1/2
x = 9/2, y = -5/2
x = 1, y = 5/2
Answer:
x = 9/2, y = -5/2
Step-by-step explanation:
5x + y = 20
10x - 2y = 50
There's multiple ways to do this, but I will solve using substitution.
Isolate variable y on the first equation.
5x + y = 20
y = 20 - 5x
Substitute the value of y for 20 - 5x in the second equation.
10x - 2(20 - 5x) = 50
Use distributive property:
10x - 40 + 10x = 50
Combine like terms:
20x - 40 = 50
20x = 90
x = 90/20
x = 9/2
Substitute x for 9/2 and solve for y:
y = 20 - 5(9/2)
y = 20 - 45/2
y = 40/2 - 45/2
y = -5/2
Answer:
x =9/2, y = -5/2
Step-by-step explanation:
5(9/2) + -(5/2)= 20
45/2 + -5/2 = 20
40/2 = 20
10(9/2) - 2(-5/2) = 50
90/2 + 10/2 = 50
45 + 5 = 50
