The dinner bill comes to $30, and you want to leave a 20% tip. What is the total cost of the bill?
Answer:
$36
Step-by-step explanation:
First, let us make an expression to solve this using the given information.
For that let the total cost be x.
Amount of the bill tip total cost
100 ⇒ 20 ⇒ 120
30 ⇒ 20 ⇒ x
Accordingly,
100 ⇒ 120
30 ⇒ x
Use cross multiplication and solve for x.
100x = 120 × 30
100x = 3600
Divide both sides by 100.
x = $ 36

Dance lessons are offered at two studios. The cost of dance lessons at each studio is shown. • Studio Q charges a $30 registration fee plus $80 per month. . Studio R charges a $105 registration fee plus $65 per month. after how many months will the total cost of the dance lessons be equal at the two studios? What will the cost be?
Answer:
5 months and the cost is $430
Step-by-step explanation:
Let's start by figuring out the equations for both dance studios.
Q : 30 registration fee plus 80 per month.
R : 105 registration fee plus 65 per month.
We can use the variable m for months.
Registration is a flat fee, so that will be it's own term. Plus the costs per month. We will multiply the costs per month times months, m.
Q : 30 + 80m
R : 105 + 65m
Now, if we want to find out how many lessons until the costs are equal, we need to make the two equations equal to each other.
80m + 30 = 65m + 105
Now, we work backwards to find out what m is.
Subtract 30 on both sides.
80m = 65m + 75
Subtract 65m on both sides
15m = 75
Divide by 15 on both sides to isolate m.
m = 5
After 5 months, the total cost of the dance lessons will be equal at the two studios. To find out the cost, we must multiply the months back in. We can substitute 5 in for any of the equations as they are equal. I will use 80m + 30.
80(5) + 30 = ?
400 + 30 = ?
430 = ?
The cost for both studios will be equal at 5 months, with a cost of $430.

The equation of asked line is y = x/3+3
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
The equation of a line passing through two points (x1, y1) and (x2, y2) is
y-y1 = (y2-y1)/(x2-x1)*(x-x1)
The two points are (6, 5) and (3, 1)
Equation =
y-5 = -4/-3*(x-6)
y-5 = 4/3*(x-6)
3y - 15 = x-6
3y = x+9
y = x/3+3
Hence, the required equation is y = x/3+3

50 POINTS!!
Answer:
p = - 123/10 = -123/10 = -12.3
Step-by-step explanation:
-3(0.5 + 3p) = -6(p - 5.9)
Use the distributive property to multiply -3 by 0.5 + 3p
-1.5 - 9p = -6 (p - 5.9)
Use the distributive property to multiply -6 by p - 5.9
-1.5 - 9p = -6p + 35.4
Add 6p to both sides
-1.5 - 3p = 35.4
Add 1.5 to both sides
-3p = 35.4 + 1.5
Add 35.4 and 1.5 to get 36.9
-3p = 36.9
Divide both sides by -3
p = 36.9/-3
Expand 36.9/-3 by multiplying both numerator and the denominator by 10.
p = 369/-30
Reduce the fraction 369/-30 to lowest terms by extracting and canceling out 3.
p = -123/10

Write an equation for the proportional relationship. Let x represent a length measured in meters and y represent the same length measured in centimeters. I don't know what would be the equation.
The equation for the proportional relationship is x=y×(1/100) where x represents length in meters and y represents same length in centimeters.
What is meant by proportionality?The phrase proportionality refers to any relationship that always has the same ratio. The quantity of apples in a crop, for example, is proportionate to the number of trees in the orchard, with the ratio of proportionality being the average number of apples per tree.
In mathematics, two sequences of numbers, generally experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is known as the coefficient of proportionality or proportionality constant.
Given,
Length(cm): Length(m)
100 : 1
250 : 2.5
78.2 : 782
123.9 : 1.239
The value that goes next to y is,
