Given:
Total cost of the call = $7.75
The charge for the first minute was $ 1. Each extra minute cost $ 0.25.
To find:
The equation for this situation and the call duration.
Solution:
Let x be the call duration in minutes.
Remaining minutes after first one minute = x-1
Cost of first minute = $1
Cost of 1 extra minute = $0.25
Cost of (x-1) extra minutes = $0.25(x-1)
Total cost of call = Cost of first minute + Cost of extra minutes
[tex]7.75=1+0.25(x-1)[/tex]
[tex]7.75=1+0.25x-0.25[/tex]
[tex]7.75=0.25x+0.75[/tex]
[tex]7.75-0.75=0.25x[/tex]
[tex]7=0.25x[/tex]
Divide both sides by 0.25.
[tex]\dfrac{7}{0.25}=x[/tex]
[tex]28=x[/tex]
Therefore, the required equation is [tex]7.75=1+0.25(x-1)[/tex] and call duration is 28 minutes.

A bicycle store costs $2250 per month to operate. The store pays an average of $40 per bike. The average selling price of each bicycle is $70. How many bicycles must the store sell each month to break even?
Answer:
75
Step-by-step explanation:
Given That :
Operation cost = $2250 per month
Purchase price per bike = $40
Average selling price per bike = $70
How many bicycles must the store sell each month to break even ;
Break even point = point at which there is net profit / loss = 0
Let number of bicycles store must sell = x
Operation cost + (purchase price * Number of bicycles) = selling price * Number of bicycles
2250 + 40x = 70x
2250 = 70x - 40x
2250 = 30x
x = 2250 / 30
x = 75
To break even 75 bicycles must be sold

Answer: 30 degrees
Step-by-step explanation:
Since the are supplementary have them equal to 180 (degrees).
(8r + 206) + (7t + 79)= 18
Combine like terms
15r + 295= 180
Subtract 295 from both sides.
15r + 295-295= 180-295
15r = -105
Divide both sides by 15
15r/15= -105/15

What is the solution to -(4x-3) = -7(9+x) ???
Answer:
The solution is -22
Step-by-step explanation:
The solution of an equation is the value of the variable of the equation
∵ -(4x - 3) = -7(9 + x)
→ Simplify each side
∵ -(4x) - -(3) = -7(9) + -7(x)
∴ (-4x) - (-3) = -63 + (-7x)
→ Remember (-)(-) = (+) and (-)(+) = (-)
∴ -4x + 3 = -63 - 7x
→ Add 7x to both sides
∴ -4x + 7x + 3 = -63 - 7x + 7x
∴ 3x + 3 = -63
→ Subtract 3 from both sides
∵ 3x + 3 - 3 = -63 - 3
∴ 3x = -66
→ Divide both sides by 3
∴ x = -22
∴ The solution is -22

3x - 24 = 81 (add 24 on both sides)
3x = 105 (divide by 3 on both sides)
x = 35 or 105/3
6.) a
-5x - 25 = 78 (1st add 25 on both sides)
-5x = 103 (2nd divide both sides by -5)
x = -20.6

Answer:
H
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 2y = 19 ( subtract 3x from both sides )
2y = - 3x + 19 ( divide all terms by 2 )
y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{19}{2}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex] → H

After an earthquake, $$ 3 7 of all claims were paid within a month. Of the remaining claims that had not yet been paid, $$ 2 5 of them were paid within the second month. What fraction of all claims were paid in the second month?
Answer:
6/35
Step-by-step explanation:
After an earthquake, $$ 3 /7 of all claims were paid within a month.
Let the total number of claims be represented by 1
Therefore, the amount of claims that were not paid within the month is calculated as:
1 - 3/7 = 4/7
Hence, 4/7 claims were not yet paid.
Of the remaining claims that had not yet been paid, $$ 2/5 of them were paid within the second month. What fraction of all claims were paid in the second month?
This is calculated as:
2/5 of the claims that were not yet paid
= 2/5 of 4/7
= 2/5 × 4/7
= 6/35

Jeremy and his aunt decided to split the 54 flowers evenly between two areas in the front of the house and one in the back. How many flowers did they have for each planting location?
Answer:
18 flowers for each area
Step-by-step explanation:
Do the amount of flowers divided by the amount of areas there are.
ie: 54/3
The third fraction or one-third of 54 will be 18 thus, 18 flowers have for each planting location.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variables called division.
For example 4/8
As per the given,
Total number of flowers = 54
54 flowers need to divide into three parts,
54/3 = 18 flowers.
Hence "The third fraction or one-third of 54 will be 18 thus, 18 flowers have for each planting location".

Modeling club A has 42 male models and 88 female model. Modeling club B has 20 male models fewer than Modeling club A. If the total number of models in both clubs is is 222, how many female models does Modeling club B have?
Given :
Modeling club A has 42 male models and 88 female model.
Modeling club B has 20 male models fewer than Modeling club A.
To Find :
If the total number of models in both clubs is 222, how many female models does Modeling club B have.
Solution :
Male model in club B is 20 less than male model in club A.
[tex]M_B = M_A-20\\\\M_B = 42-20\\\\M_B = 22[/tex]
It is given that total number of models are 222.
[tex]M_A + M_B + F_A + F_B = 222\\\\42 + 22 + 88 + F_B = 222\\\\F_B = 222-152\\\\F_B = 70[/tex]
Therefore, female models on club B are 70.
