Answer:
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
Step-by-step explanation:
Given that:
Cost of cell phone at Verizon = $300
Monthly fee = $40
Let,
x be the number of months
V(x) = 40x + 300
Cost of cell phone at T-mobile = $200
Monthly fee = $60
T(x) = 60x + 200
For equal amount of money,
V(x) = T(x)
40x+300=60x+200
300-200=60x-40x
100=20x
20x=100
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{100}{20}\\x=5[/tex]
Hence,
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 3100 seats. The students left 1395 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answer: 55% of the seats in the theater were filled by the 6th graders on the trip.
Step-by-step explanation:
Given: Total seats = 3100
Seats vacant= 1395
Seats occupied by 6th graders = 3100-1395 = 1705
The percentage of the seats in the theater were filled by the 6th graders on the trip = [tex]\dfrac{\text{Seats occupied by 6th graders}}{\text{Total seats}}\times100[/tex]
[tex]=\dfrac{1705}{3100}\times100\\\\= 55\%[/tex]
Hence, 55% of the seats in the theater were filled by the 6th graders on the trip.

A straight line has gradient 4 and passes through the point (5,23).
Work out the equation of the line.
Answer:
Equation of line is: [tex]\mathbf{y=4x+3}[/tex]
Step-by-step explanation:
We are given:
A straight line has gradient 4 and passes through the point (5,23).
Work out the equation of the line.
The equation of line will be in slope-intercept form: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept
Finding slope
We have slope (gradient) m = 4
Finding y-intercept
Using slope m = 4 and point (5,23) we can find b i.e y-intercept
[tex]y=mx+b\\23=4(5)+b\\23=20+b\\b=23-20\\b=3[/tex]
So, we get y-intercept b = 3
Finding Equation of Line
Now, writing equation of line having slope m = 4 and y-intercept b = 3 is:
[tex]y=mx+b\\y=4x+3[/tex]
So, the Equation of line is: [tex]\mathbf{y=4x+3}[/tex]

Shakira and Evelyn disagree on the method used to find the perimeter of an equilateral triangle whose side measures 4n-2. Whose method is correct? Explain. Shakira's method: 3(4n-2) Evelyn's method: (4n-2)+(4n-2)+(4n-2)
Answer:
Both are correctStep-by-step explanation:
All the sides of an equilateral triangle are equal. Hence;
Perimeter of an equilateral triangle = 3S
S is one of the side length
Given;
S = 4n-2
Perimeter of the triangle = 3(4n-2)
This can also be expressed as P = S + S + S
P = (4n-2) + (4n-2) + (4n-2)
This shows that both methods are correct

Step-by-step explanation: (3,-5), because that's the point where the two lines intersect.
Y=-2x+1
Y=-3/2x-1/2
Substitute the Y to get -2x+1=-3/2x-1/2
1/2x=3/2
x = 3
Now plug x into first equation: y=-2*3+1=-5
so the intersection point is (3,-5)

What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
The expression is,
⇒ 1/4 + x = 2/3
Where, x is unknown.
Now, We have to solve the expression for the value of x as;
⇒ 1/4 + x = 2/3
Subtract 1/4 both side,
⇒ 1/4 + x - 1/4 = 2/3 - 1/4
⇒ x = (8 - 3) / 12
⇒ x = 5/12
