Savannah loves to talk on her cell phone. She has $100 in her budget to pay this month’s cell phone bill. Her cell phone plan is $20 per month plus $0.10 per minute of usage. If x represents the minutes of usage, which equation best represents the word problem?
A. 100+20=.10x
B. 100+.10x=20
C. 20 +.10x=100
D. 20-.10x= 100
Answer: C. best fits the word problem.
Step-by-step explanation:
The reason C. best fits is because the bare minimum $20 she has to pay plus .10 times whatever amount of minute's she spends talking has to equal $100 for her to stay in budget. A good example would be say she spends 800 minutes in total on her phone. 0.10 times 800 is 80. So in this hypothetical situation, it would be 20 + 80 = 100.

At Break Time Bakery, donuts are 0.75 each and drinks cost $1.50 each. Which equation best represents y, total cost of purchasing x number of donuts and a drink?
Answer: B
Step-by-step explanation:
Answer:

Step-by-step explanation:
Choose a linear function for the line represented by the point-slope equation y-5= 3(x - 2).
O f(x) = 3r+1
O f(x) = 3x - 1
O f(x) = &r + 10
O flac) = 8x - 10
Answer:
y = 3x - 1
Step-by-step explanation: All you have to do here is solve the equation for y. When you add 5 to both sides, you are left with 3(x-2) + 5. Now, you just have to open the parentheses, giving you 3x-6+5, or 3x-1.

Answer:
Angle A = 65 degrees, Angle B = 78 degrees
Step-by-step explanation:
Since a triangle always has its vertices add up to 180 degrees to be a triangle, we can setup an equation on how to solve it. Adding all the vertices together into a formula to equal 180 degrees gives you 5x-5 = 180. Solving this equation will grant you an answer of x = 37 degrees, and taking this value and plugging it in for each requested angle is how to find the exact degree value. Angle A will just be 2(37) - 9, which ends up to be 65 degrees. Angle B is just 2(37) + 4, which becomes 78 degrees. (You can check the answer by taking all values and adding them together to equal 180. 78 + 65 + 37 = 180.) Hope that helps!
Answer: ∠A = 65° ∠B = 78°
The sum of all interior angles = 180°. So, set 180 equal to the angles you were given (in this case, 2x-9, 2x+4, and x), and solve for x.
180 = (2x-9) + (2x+4) + x (combine the like terms)
180 = 5x - 5 (isolate 5x by moving -5 to the other side)
5x = 180 + 5
5x = 185 (divide both sides by 5 to isolate for x)
x = 37°
Then, sub in the value of x (in this case, 37°) into ∠A and ∠B.
∠A = (2x-9) = 2(37)-9 = 65°
∠B = (2x+4) = 2(37)+4 = 78°
∴ ∠A = 65° and ∠B = 78°.

The cost of an apple was 0.62 cents.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
An equation is a mathematical statement that shows that two mathematical expressions are equal.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
An equation says that two things are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, Bill bought 5 apples Mary bought 2 apples and spent 1.86 for strawberries. both the spent equal amounts, we need to write and solve the equation for the price of apples,
Let the cost of 1 apple = A
Bill bought = 5A apples
Mary bought=2A + 1.86
5A = 2A + 1.86
3A = 1.86
A = 1.86/3
A = 0.62 cents
Hence, the cost of an apple was 0.62 cents.

The circumference of a circle is 10 inches. What is its area in square inches?
Answer:
7.96 square inches.
Step-by-step explanation:
Area of a circle given a circumference is given by formula:
[tex]A = \frac{C^{2}}{4\pi}[/tex]
So substituting into equation we have: [tex]C= 10[/tex].
Therefore [tex]A = 10^{2}/4\pi = 100/4\pi=25/\pi =7.96[/tex] square inches.
The area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The circumference of a circle is 10 inches.
As we know the circumference of a circle is given by:
C = 2πr
C is the circumference of the circle.
r is the radius of the circle.
10 = 2πr
r = 5/π inches
As we know,
The area of the circle is given by:
A = πr²
Here, A represents the area of the circle.
Plug the value of the radius r in the above formula:
A = π(5/π)²
A = 25/π square inches
Take π = 3.14
A = 25/3.14
A = 7.96 sqaure inches
Thus, the area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

Dora, the school lunch manager, says that it takes 225 oranges to make 5 gallons of orange juice how many oranges does Dora need to make one gallon?
Answer:
45
Step-by-step explanation:
Since
5 : 225 = 1 : X
Then we know
225/5 = X/1
Multiplying both sides by 1 cancels on the right
1 × (225/5) = (X/1) × 1
1 × (225/5) = X
Then solving for X
X = 1 × (225/5)
X = 45
Therefore
5 : 225 = 1 : 45
Answer:45
