Answer:
They were charged 300 minutes of phone calls.
Step-by-step explanation:
$30.35 was the monthly charge for this service provider. Subtract that from the $45.35 which would leave $15. $15 divided by $.05 = 300. 300 minutes is your answer.

Answer:
(2 n)/3-2/3 = n/6+4/3
(2 n)/3-2/3 = (2 n-2)/3:
(2 n-2)/3 = n/6+4/3
Put each term in n/6+4/3 over the common denominator 6: n/6+4/3 = n/6+8/6:
(2 n-2)/3 = n/6+8/6
n/6+8/6 = (n+8)/6:
(2 n-2)/3 = (n+8)/6
Multiply both sides by 6:
(6 (2 n-2))/3 = (6 (n+8))/6
6/3 = (3×2)/3 = 2:
2 (2 n-2) = (6 (n+8))/6
(6 (n+8))/6 = 6/6×(n+8) = n+8:
2 (2 n-2) = n+8
Expand out terms of the left hand side:
4 n-4 = n+8
Subtract n from both sides:
(4 n-n)-4 = (n-n)+8
4 n-n = 3 n:
3 n-4 = (n-n)+8
n-n = 0:
3 n-4 = 8
Add 4 to both sides:
3 n+(4-4) = 8+4
4-4 = 0:
3 n = 8+4
8+4 = 12:
3 n = 12
Divide both sides of 3 n = 12 by 3:
(3 n)/3 = 12/3
3/3 = 1:
n = 12/3
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

It is estimated that there are 1.2×1057 atoms in the Sun. The number of atoms in the rest of the Solar System is approximately 1.2×1056. About how many more atoms exist in the Sun than in the rest of the Solar System? Drag numbers to complete the answer in scientific notation.
Answer:
1.08 * 10^57
Step-by-step explanation:
Given that:
Number of atoms in the sun = 1.2 * 10^57
Number of atoms in the rest of the solar system = 1.2 * 10^56
About how many more atoms exist in the Sun than in the rest of the Solar System?
Subtract the number of atoms in solar system from number of atoms in sun
(Number of atoms in sun - number of atoms in rest of the solar system)
(1.2 * 10^57) - (1.2 * 10^56)
= 1.08 * 10^57 (using calculator)
5. Find the slope of the line
PLZZ Help me
Answer:
y = -2x
Step-by-step explanation
slope intercept form: y = mx + b
m is slope and b is y-intercept
1. lets find y-intercept cuz thats easiest
the line crosses (0,0) at the y-axis so there is no y-intercept
2. to find slope rise/run
we'll start at (0,0) since that's the y-intercept
3. slope is rise/run = -2/1 = -2
it's negative becuase it's going left
_____________________________________________________
another way you can find slope is by the equation y2 - y1/ x2 - x1
take 2 random points from the line, i will use (0,0) and (-2,4)
4 - 0/ -2 - 0 = 4/-2 = -2
slope is -2

How do you graph Y=1.2x-4 ?
Step-by-step explanation:
Use the y=mx+b reference
the b refers to the y intercept which in your case is -4
so on the graph you would put -4 on the y line so at (0,-4)
Then the m or the slope which is 1.2 means from the point (0,-4) you move 1.2 units up and 1 unit to the right forever to create your line so you continuously move 1.2/1 and -1.2/-1
The required, graph of the linear equation y = 1.2x-4 is shown in the image attached below.
To graph the equation y = 1.2x - 4:
Set up the coordinate plane with the x and y axes.Label the axes as "x" and "y" with numerical markers.Plot the y-intercept: When x = 0, y = 1.2 * 0 - 4 = -4. Plot the point (0, -4).Identify the slope: The coefficient of x is 1.2, which represents the slope.Use the slope to find another point: Starting from (0, -4), move 1 unit to the right (increase x by 1) and 1.2 units upward (increase y by 1.2). Plot the point (1, -2.8).Draw a straight line through the two points you plotted.The graph of Y = 1.2x - 4 will be a straight line that passes through the points (0, -4) and (1, -2.8), and it will continue infinitely in both directions. The line will slope upwards from left to right with a slope of 1.2.

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase. Expand the expression and round to the nearest hundredth. Drag numbers complete the expression. Numbers may be used once, more than once, or not at all. 0.090.50.971.251.451.6567.5 + s
Answer:
1.65 + 0.09s
Step-by-step explanation:
Given that :
Cost of speaker = $22
Cost per song = $1.25
Sales tax rate = 7.5%
Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)
Expanding the expression :
0.075(22 + 1.25s)
(0.075 * 22) + (0.075 * 1.25s)
1.65 + 0.09375s
Rounding to the nearest hundredth :
Sales tax on entire purchase :
1.65 + 0.09s

Answer:
m = 2
Step-by-step explanation:
The given equation is :
8x – 4y - 9 = 0
The general equation of a line is given by :
y = mx+b ...(1)
here m is slope and b is y-intercept
Equation (1) can be written as :
8x – 4y = 9
Dividing both sides by (-4)
[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)
Comparing equation (1) and (2), we get :
m = 2
Hence, the slope of the line is 2.

Write the equation of the line PERPENDICULAR to x = -12 passing through (4,5)
Answer:
hope ithelps :)
Step-by-step explanation:
1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.
And horizontal lines go through the y-axis and have equations of y= a #
2)the point on the vertical line is (4,-5), it has a y-value of -5
****Every y value on a horizontal line will be the same
so the equation for a perpendicular line would be y= -5

An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).
The table of (d) is proportional, with a constant of proportionality of 6.5.

Comment on (c)
In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.
