Answer:
one cup of coffee costs $2, while one bottle of water costs $1
Step-by-step explanation:
We can represent this using two equations:
Variable x represents cups of coffee, and variable y represents bottles of water.5x + 2y = 12
4x + 7y = 15
Your answer for the value of x and y should be
x = 2
y = 1
Therefore, one cup of coffee costs $2, while one bottle of water costs $1.

Cardania bought a car for $12,000 ten years ago, and it has been depreciating (decreasing in value) at a rate of 8% per year since she drove it off the showroom floor.
How much is the car worth today (10 years after her purchase)?
Answer:
The car is worth about 5212.66$ 10 years after her purchase.
Step-by-step explanation:
12000(1-0.08)^10=5212.661451
Laney bought some candy from the bulk food store. She bought a 290 gram bag of gummy worms, a 450 gram bag of sour keys, and 670 gram bag of chocolate covered almonds. What is the total weight in kilograms?
Answer:
1.41 kilograms
Step-by-step explanation:
Given data
290-gram bag of gummy worms
450-gram bag of sour keys
670-gram bag of chocolate-covered almonds
In all, she bought
=290+450+670
=1410grams of candy
Now let us convert from grams to kilograms
1000grams is equal to 1 kilogram
hence 1410 grams will be x
cross multiply
1000x= 1410
x= 1410/1000
x= 1.41 kilograms
Mr. White is renting an oversized truck for one week and a few additional days d. He does not have to pay a per mile fee. Evaluate the expression 325+100d to find how much he will pay for a 13-day rental. Each day = $100
Answer:
$1,625
Step-by-step explanation:
Given:
Total cost = 325 + 100d
Where,
325 = fixed cost
100 = cost per day
d = number of days
Find the total cost when d = 13 days
Total cost = 325 + 100d
= 325 + 100d
= 325 + 100(13)
= 325 + 1,300
= 1,625
Total cost = $1,625

Consider the quadratic expression below.
Answer:
x = -3 and x = 2
Step-by-step explanation:
The expression for the quadratic equation is as follows:
(x+3)(x-2)
For (x+3)(x-2) to equal 0, either (x+3) or (x-2) must be equal to 0. So,
(x+3) = 0 and (x-2) = 0
It implies,
x = -3 and x = 2
So, the values of x are -3 and 2.
what is the solution of x equals 2 + sqrt x - 2
a.) x=2
b.)x=3
c.)x=2 or x=3
d.) no solution
Answer:
x = 2 or x = 3
Step-by-step explanation:
x = 2 + sqrt(x - 2)
x - 2 = sqrt(x - 2) You could divide both sides by sqrt(x - 2)
sqrt(x - 2) = 1 Square both sides
x - 2 = 1 Add 2 to both sides
x = 3
There is a second way.
x - 2 = sqrt(x - 2) Square
x^2 - 4x + 4 = x - 2 Transfer x - 2 to the left
x^2 - 5x + 6 = 0 Factor
(x - 2)(x-3) = 0 Find the roots.
x - 2 = 0
x = 2
x - 3 = 0
x = 3
We have to check both results.
x = 2 + sqrt(x - 2)
2 = 2 + sqrt(2 -2)
2 = 2 + 0
2 = 2 This seems to work.
x = 2 + sqrt(x - 2)
3 = 2 + sqrt(3 - 2)
3 = 2 + sqrt(1)
3 = 2 + 1
3 = 3 And this works.
What is the twelfth term in the sequence with nth term formula 5/6+1/2n? Give your answer as a top-heavy fraction in its simplest form.
Given:
The formula for nth term of a sequence is:
[tex]\dfrac{5}{6}+\dfrac{1}{2}n[/tex]
To find:
The 12th term in the given sequence.
Solution:
Consider the formula for nth term of a sequence:
[tex]a_n=\dfrac{5}{6}+\dfrac{1}{2}n[/tex]
Putting [tex]n=12[/tex], we get
[tex]a_{12}=\dfrac{5}{6}+\dfrac{1}{2}{12}[/tex]
[tex]a_{12}=\dfrac{5}{6}+6[/tex]
[tex]a_{12}=\dfrac{5+36}{6}[/tex]
[tex]a_{12}=\dfrac{41}{6}[/tex]
Therefore, the 12th in the given sequence is [tex]\dfrac{41}{6}[/tex].

42 is _______32 + 32.
Therefore, △JKL is _________
52 is ________32 + 42.
Applying the same method, △ABC is ________
Answer:
See Below.
Step-by-step explanation:
Remember that:
If c² > a² + b², then we have an obtuse triangle. If c² < a² + b², then we have an acute triangle. And if c² = a² + b², then we have a right triangle.Where c is the longest side, and a and b are the two remaining sides.
[tex]4^2\text{ is }\textbf{ less than (or $<$) } 3^2+3^2[/tex]
[tex]\text{Therefore, }\Delta JKL \text{ is }\textbf{an acute triangle.}[/tex]
(16 is less than 9 + 9 or 18.)
[tex]5^2\text{ is } \textbf{equal to (or $=$) } 3^2+4^2[/tex]

If a car can travel 78 miles using 3 gallons of gas, what is the unit rate?
Answer:
26
Step-by-step explanation:
Well since a car can travel 78 miles Using 3 gallons
78/3=26
26 miles for each gallon
Answer:
26
Step-by-step explanation:
The unit rate refers to the distance the car can travel using 1 gallon of gas. One way to solve this is to create an algebraic equation like [tex]78=3x[/tex]. Then, to find the unit rate isolate x by dividing both sides by 3. This means that the unit rate is 26.
convert from vertex form to standard form... y= -(x-3)^2-8
Answer:
-x² + 6x - 17
Step-by-step explanation:
First, expand (x-3)² using FOIL
(x - 3)(x - 3)
= x² - 6x + 9
Distribute the negative sign to the expression:
-(x² - 6x + 9)
-x² + 6x - 9
Now, subtract 8 from this
-x² + 6x - 9
= -x² + 6x - 17
So, the equation in standard form is -x² + 6x - 17
The answer is.. x^2+6x-17
What is the surface area of the right prism below?
A. 360 sq. units
B. 384 sq. units
C. 432 sq. units
D. 336 sq. units
The surface area of the right prism cone is,
⇒ 1960 units²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A right prism shown in image.
Now, We get;
Base area of cone = 14 x 10
= 140
And, Height of cone = 6
And, Perimeter of the base = 2 (10 + 14)
= 280
Thus, WE know that;
The surface area of the right prism cone is,
⇒ 2B + hP
⇒ 2 × 140 + 6 × 280
⇒ 280 + 6 × 280
⇒ 280 + 1680
⇒ 1960 units²
Thus, The surface area of the right prism cone is,
⇒ 1960 units²
