2. there are two phone plans. One plan a $28 monthly fee, and cost 9 cents per minute. The second plan is 13 cents per minute, and $ 30 monthly fee.
A. Write and equations to represent the number of minutes use in a month that will make the plans cost the same?
B. Solbe the equation to find the number of minutes
_________________________________________________________________
3. cell phone plan costs per month for unlimited calling plus $0.15 per text message.
A. write a linear model that represents the monthly cost of this cell phone plan if the user sends t text messages
b. if you send 200 text messages, how much would you pay according to this cell phone plan?
Answer:
for the first one the answer is 28-9=18 and 30-13=17 are not the same but are close and for the second one the answer is $30 for the phone plan cause 200×0.15=30
If you use 50 minutes in a month, both plans will cost $32.50.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
2.
A. Let x be the number of minutes used in a month. Then, the cost of Plan A is given by:
Cost(A) = 0.09x + 28
The cost of Plan B is given by:
Cost(B) = 0.13x + 30
To find the number of minutes that will make the plans cost the same, we need to set Cost(A) equal to Cost(B) and solve for x:
0.09x + 28 = 0.13x + 30
0.04x = 2
x = 50
Therefore, the plans will cost the same if you use 50 minutes in a month.
B. If you use 50 minutes in a month, the cost of Plan A will be:
Cost(A) = 0.09(50) + 28 = 32.50
The cost of Plan B will also be:
Cost(B) = 0.13(50) + 30 = 36.50
Therefore, if you use 50 minutes in a month, both plans will cost $32.50.
3.
A. Let C be the monthly cost and t be the number of text messages sent. Then, the linear model that represents the monthly cost is:
C = 0.15t + base cost
The base cost is the cost for unlimited calling, which is not specified in the problem.
B. If you send 200 text messages, the monthly cost will be:
C = 0.15(200) + base cost
C = 30 + base cost
The total cost will depend on the base cost for unlimited calling.

5 2/3 gave to her 4 friends how much did each one receive
Answer:
Let's see what to do buddy...
Step-by-step explanation:
If it is 5 + 2/3
_________________________________
Step (1)
First we have to find all she has :
[tex]5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3} [/tex]
_________________________________
Step (2)
To find how much did each of them receive , we must divided all by the number of her friends which is 4.
So we have :
[tex] \frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\ [/tex]
So each of her friends receive 17/12 .
_________________________________
_________________________________
_________________________________
If it is 5 × 2/3
_________________________________
Step (1)
Firs we have to find all she has :
[tex]5 \times \frac{2}{3} = \frac{10}{3} \\ [/tex]
_________________________________
Step (2)
To find how much did each of them receive , we must divided all by the number of her friends which is 4.
So we have :
[tex] \frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\ [/tex]
So each of her friends receive 10/12 .
_________________________________
And we're done.
Thanks for watching buddy good luck.

find the slope of the line using the ordered pairs (-1, -3/4) and (4, -3)
Answer:
- 2.25/3
Step-by-step explanation:
You start driving from Austin to Houston with a constant speed of 120km/hr (75 mph). After 1.5 hr you stop for 0.5 hr. Then you continue driving with a new constant speed v2 and reach Houston 45 mins later. If the total distance from Austin to Houston is 265km, what is the speed v2?
Answer:
113.33 km/hr
Step-by-step explanation:
Given that :
From Austin
Drive 1 : Speed of 120km/hr for 1.5 hours
Stop time = 0.5 hour
Drive 2 : speed of v2 for 45 minutes to finally reach Houston
Total distance (Austin to Houston) = 265 km
Total distance : (distance on drive + distance on second drive)
Distance = speed * time
(120 * 1.5) + (v2 * 45/60) = 265
180 + 0.75v2 = 265
0.75v2 = 265 - 180
0.75v2 = 85
v2 = 85 / 0.75
v2 = 113.33km/hr
v2 = 85 / 0.75
v2 =

KL = 2x + 2
JL = 55, and
JK = 7* +8,
Find KL.
J
K
L
Answer:
KL = 12Step-by-step explanation:
JK + KL = JL
where:
JK = 7x + 8
KL = 2x + 2
JL = 55
plugin values into the equation:
7x + 8 + 2x + 2 = 55
7x + 2x = 55 - 8 - 2
9x = 45
x = 45 / 9
x = 5
KL = 2x + 2
KL = 2(5) + 2
KL = 12
What are the solutions to f(x) = g(x)?
x = 0 and x = 1
x = -2 and x = 5
x = 0 and x = -3
x = 10 and x = -8
Answer:
x = 0 and x = 1
Step-by-step explanation:
From the table of values
f(x) = g(x) = 1 when x = 0 , and
f(x) = g(x) = 0.25 when x = 1
The solution to f(x) = g(x) are x = 0 and x = 1

The length of a rectangle is (x-8) units, and its width is(x+11) units. What is an expression for this.
Answer:
(x²+3x-88) square units
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
length of a rectangle is (x-8)units
Its width is (x+11) units.
Required
Expression for the area of the rectangle
Substituting the given function into the formula.
Area of the rectangle = (x-8)(x+11)
Area of the rectangle = x(x)+11x-8x-88
Area of the rectangle = x²+3x-88
Hence the expression that represents the area of the rectangle is x²+3x-88 units²

An object is traveling at a steady speed of 10 1/10 km/h. How long will it take the object to travel 1 9/10 km?
Answer:
It will take [tex]\frac{19}{101}[/tex] hour.
Step-by-step explanation:
The rule of the distance is:
Distance = speed × time
∵ An object is traveling at a steady speed of [tex]10\frac{1}{10}[/tex] km/h
∴ The speed = [tex]10\frac{1}{10}[/tex] km/h
∵ The object will travel [tex]1\frac{9}{10}[/tex] km
∴ The distance = [tex]1\frac{9}{10}[/tex] km
→ We need to find how long will it take it to travel this distance
→ Substitute the values of distance and speed in the rule above
∵ [tex]1\frac{9}{10}[/tex] = [tex]10\frac{1}{10}[/tex] × time
→ To find the time divide both sides by [tex]10\frac{1}{10}[/tex]
∴ The time = [tex]1\frac{9}{10}[/tex] ÷ [tex]10\frac{1}{10}[/tex]
→ Change the mixed numbers to an improper fraction
∵ [tex]1\frac{9}{10}[/tex] = [tex]\frac{(1)(10)+9}{10}=\frac{19}{10}[/tex]
∵ [tex]10\frac{1}{10}=\frac{(10)(10)+1}{10}=\frac{101}{10}[/tex]
∴ The time = [tex]\frac{19}{10}[/tex] ÷ [tex]\frac{101}{10}[/tex]
- Reverse the fraction after the division sign, then change ÷ to ×
∴ The time = [tex]\frac{19}{10}[/tex] × [tex]\frac{10}{101}[/tex]
→ 10 up will cancel 10 down
∴ The time = [tex]\frac{19}{101}[/tex] h
It will take [tex]\frac{19}{101}[/tex] hour.
