Answer:
The first step would be to plot the y-intercept. In this equation, the y-intercept is 5. The ordered pair is (0, 5), because (x, y).
You go up 5 from the origin (the center of the graph, (0, 0) ), and plant a dot on the y-axis.

first we'll do the LCM of both sides denominator 3 and 3=3
and multiply this with both side
3×8/3c - 2×3= 3×2/3c - 3×12
8c-6= 2c-36

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3mile to a bus stop and then takes a bus for 2 1/2miles. Which expression shows how many miles Emilie travels in all?
Given :
Emilie rides her bike x miles before she gets a flat tire.
She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.
To Find :
Which expression shows how many miles Emilie travels in all.
Solution :
We know, total distance covered is given by sum of all the distance she travelled.
Distance covered, D = x + 1/3 + 2 1/2
D = x + 1/3 + 5/2
D = (6x + 2 + 15)/6
D = (6x + 17)/6
Therefore, total distance travelled by Emilie is (6x + 17)/6 .

Billy has a gift card with a $145 balance. He buys several video games that cost $45 each. After the purchases, his gift card balance is $10. Enter an equation to help find out how many video games Billy bought.
Answer:
Equation is 145 - 45 x = 10.
Billy bought 3 video games.
Step-by-step explanation:
As given,
Total Balance in the gift card = $145
The cost of each video game = $45
After purchasing , Balance in Gift card = $10
Now,
Let Total number of video games Billy purchase = x
⇒Cost for video game = 45x
Now,
As we know ,
Total Balance - Purchased Item = Balance left
⇒ 145 - 45 x = 10
∴ The equation is 145 - 45 x = 10
Now,
145 - 10 = 45x
⇒135 = 45x
⇒ x = [tex]\frac{135}{45}[/tex] = 3
∴ we get
Billy bought 3 video games
Which expression matches the situation?
You went to the mall with $90.00. You bought three shirts that cost x dollars each.
How much money do
you have left after buying the shirts? Which one matches please help
Answer:
The expression that matches the situation is 90.00 - 3x ⇒ 1st answer
Step-by-step explanation:
Let us solve the question
∵ You went to the mall with $90.00
→ That means the total money with you = $90.00
∴ The total money = 90.00 dollars
∵ You bought three shirts that cost x dollars each
∴ The cost of a shirt = $x
∴ The number of shirts = 3
→ Find the total cost of the three shirts
∴ The cost of the shirts = 3 × x
∴ The cost of the shirts = 3x dollars
∵ The money left = the total money - the cost of the shirts
→ Substitute the value of total money and the cost of the shirts
∴ The amount of money left = 90.00 - 3x
∴ You have left with 90.00 - 3x dollars
∴ The expression matches the situation is 90.00 - 3x dollars

For this item, enter the answer in the space provided. A concession stand at school is selling cups of tea and hot chocolate after school. A student can buy 3 cups of tea and1 cup of hot chocolate for $12.00 or 1 cup of tea and 2 cups of hot chocolate for $14.00. Each cup of tea costs $______
Answer: 2
Step-by-step explanation:
Each cup of tea costs $10.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let consider X = cups of tea and Y= cup of hot chocolate
Therefore, the system of equation is,
3x + y = 12
x + 2y = 14
Solving;
-2(3x + y = 12)
-6x - 2y = -24
x + 2y = 14
Now, add;
-5x = -10
y = 2
Now substitute;
x + 2y = 14
x + 2(2) = 14
x = 10
Each cup of tea costs $10.

find the first term and the common difference of an arithmetic progression in which t5=3x-y and t11=5y
t5 refers to term 5 and t11 refers to term 11
first term: 5x-5y
common difference: -x/2 + y
The common difference is d = -0.5x + y and the first term is 5x-5y
Geometric progressionThe nth term of the geometric progression is expressed as:
[tex]T_n=a+(n-1)d[/tex]
where;
a is the first termr is the common ration is the number of termsThe fifth term of the sequence is expressed as:
[tex]T_5=a+4d=3x-y[/tex]
[tex]T_{11}=a+10d=3x-y[/tex]
Take the difference of the terms:
[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]
Get the first term:
a = 3x - y - 4(-0.5x+y)
a = 3x - y + 2x - 4y
a = 5x - 5y
Hence the common difference is d = -0.5x + y and the first term is 5x-5y

The given formula can be used to determine the volume (V) of a cylinder.
V= Bh = area of base x height
Which of the following is the best approximation of the volume of the cylinder below?
Step-by-step explanation:
it seems the answer is c. 3514 in3
Approximate value of the volume of cylinder is equals to 3514 in³.
What is volume?"Volume is defined amount of space occupied by any 3 dimensional body. It is useful to represents the capacity of any object ."
Formula used
Area of the base = πr²
Volume of a cylinder = area of the base × height
= πr²h
Value of π = 3.14
According to the question,
Diameter of cylinder = 11 in
Radius (r) = Diameter / 2
= 11 / 2
= 5.5 in
Height (h) = 37 in
Substitute the value in the formula we get,
Volume of cylinder = 3.14 ×(5.5)² × 37
= 3514.445 in³
≈ 3514 in³
Hence, approximate value of the volume of cylinder is equals to 3514 in³.

A bank offers an annual simple interest rate of 6% on home improvement loans. How much would Tobias OWE IN ALL if he BORROWED $12,000 over a period of 3 years?
Answer: $14160
Step-by-step explanation:
Simple interest would be calculated as:
= PRT/100
where,
P = Principal = $12000
R = Rate = 6%
T = Time = 3 years
Simple interest = ($12000 × 6 × 3)/100
= $216000/100
= $2160
The amount that Tobias owe in all would be:
= $12000 + $2160
= $14160

Mary is twice as old as her brother Zane.Zane is four years less than twice as old as his cousin chase.If chase is 4 years old,how old is Mary?
Answer:
Mary is 8 and that Zane and Chase are both 4 years old.
Step-by-step explanation:
For this equation, we will say Mary = M, Zane = Z, and Chase = C.
We will now convert the word problem into equations.
[tex]2m = z, 2c - 4 = z, c = 4[/tex]
Now I will solve the equations by putting C into the equation.
[tex]2(4) = 8, 2(4) - 4 = 4, c = 4[/tex]
So we can see that Mary is 8 and that Zane and Chase are both 4 years old.

Find the length of arc AB
Answer:
OH HELL NO!
Step-by-step explanation:
Answer:
[tex] m\widehat {AB} = 144\degree [/tex]
[tex]m\widehat {ACB} = 216\degree [/tex]
Step-by-step explanation:
Let the measures of the given arcs be 2x and 3x.
[tex] \because m\widehat {AB} \:\&\: m\widehat {ACB} [/tex] sums up to form a circle.
Therefore,
2x + 3x = 360°
5x = 360°
x = 360°/5
x = 72°
2x = 2*72 = 144°
3x = 3*72° = 216°
[tex] \therefore m\widehat {AB} = 144\degree [/tex]
[tex] \& m\widehat {ACB} = 216\degree [/tex]

Answer:
well ik Yearly it would be 93$ and monthly it would be 93$
Step-by-step explanation:
It is important to remember that these scenarios are hypothetical and that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are generally subject to higher risk and volatility. The actual rate of return on investments can vary widely over time, especially for long-term investments. This includes the potential loss of principal on your investment. It is not possible to invest directly in an index and the compounded rate of return noted above does not reflect sales charges and other fees that investment funds and/or investment companies may charge.
