STEPS FOR SOLVING LINEAR EQUATION[tex]20-2(x=5)=24[/tex]
Use the distributive property to multiply −2 by x−5.
[tex]20-2x+10=24[/tex]
Add 20 and 10 to get 30.
[tex]30-2x=24[/tex]
Subtract 30 from both sides.
[tex]-2x=24-30[/tex]
Subtract 30 from 24 to get −6.
[tex]-2x=-6[/tex]
Divide both sides by −2.
[tex]x=\frac{-6}{-2}[/tex]
Divide −6 by −2 to get 3.
[tex]x=3[/tex]

Answer:
$45
Step-by-step explanation:
x / 30 = 150 / 100
100x = 4500
x = 45
Answer:
$45
Step-by-step explanation:
To solve this, cross multiply:
[tex]\frac{x}{30} =\frac{150}{100}[/tex]
100x = 4500
Divide 100 from both sides.
x = 45

A regular polygon is shown with one of its angle measures labeled a. If m∠a = (2z + 64)°, find the value of z.
Answer:
the sum of all the angles of the polygon is 180°
Then,
(2z+64)° = 180°
2z = 180° - 64°
2z = 116°
z = 116 / 2
= 58° (ans)
Answer:
58

how can you find the new amount of a quantity that has increased over a period of time
Answer:
Step-by-step explanation:/ Answer
1. First: work out the difference (increase) between the two numbers you are comparing.
2. Increase = New Number - Original Number.
3. Then: divide the increase by the original number and multiply the answer by 100.
4. % increase = Increase ÷ Original Number × 100.
At a restaurant, hot chocolate can be purchased in two different cup sizes. A 12-ounce cup costs $4.80 and a 16-ounce cup costs $6.40.
Is the linear relationship between cup size and cost also proportional? Why or why not?
Yes, there is no constant of proportionality.
Yes, the constant of proportionality is 0.4.
No, the constant of proportionality is 0.4.
No, there is no constant of proportionality.
Answer:
Yes, the constant of proportionality is 0.4.
Step-by-step explanation:
[tex] \frac{4.80}{12} = \frac{48}{120} = \frac{2}{5} = .4[/tex]
[tex] \frac{6.40}{16} = \frac{64}{160} = \frac{2}{5} = .4[/tex]
Yes, the given relation is proportional with a constant of proportionality is 0.4 thus option (B) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
A 12-ounce cup costs $4.80.
The ratio of cost to ounce = 4.80/12 = 0.4
A 16-ounce cup costs $6.40.
The ratio of cost to ounce = 6.40/16 = 0.4
So constant of proportionality is 2.5.
Hence "Yes, the given relation is proportional with a constant of proportionality is 0.4".

An indoor soccer field can be rented for personal use. The total cost for renting the field can be found by using the equation y = 225x + 200. The x-variable is the number of hours the field is being rented, the constant is the flat rate for renting the field, and the y-variable is the total cost, in dollars.
Which statement is true based on the given equation?
The equation shows a linear relationship, but not a proportional relationship.
The equation shows a linear relationship and a proportional relationship.
The equation does not show a linear relationship or a proportional relationship.
The equation shows a proportional relationship, but not a linear relationship.
The statement that is true based on the given equation is (c) The equation does not show a linear relationship or a proportional relationship.
How to determine the true statement?
The equation of the function is given as:
y = 25x^2 + 60
Linear equations can take any of the following forms
Ax + By = C
y = mx + c
y - y1 = m(x - x1)
Any equation that takes a form different from the above forms is not a linear equation
Hence, the statement that is true based on the given equation is (c) The equation does not show a linear relationship or a proportional relationship.

Suppose a hurricane traveled 130 miles from point in the Atlantic Ocean to Florida coastline in 6 1/2 hours. How many miles per hour did the hurricane travel?
Answer:
The hurricane traveled 260 miles per hour.
Step-by-step explanation:
Given,
Distance covered by hurricane = 130 miles
Then time = [tex]\frac{6}{12}[/tex] hours=[tex]0.5[/tex] hour
Distance=Speed*Time
Speed=[tex]\frac{Distance}{Time}[/tex]
Speed=[tex]\frac{130}{0.5}[/tex]
Speed=260 miles per hour
So, the hurricane traveled 260 miles per hour

Write the math sentence as an equation: Negative eight times the sum of a number and 14.6 is 31.2.
−8r + 14.6 = 31.2
−8(r + 14.6) = 31.2
−8(r − 14.6) = 31.2
−8r − 14.6 = 31.2

The equation for the math sentence "Negative eight times the sum of a number and 14.6 is 31.2." will be; -8(r+14.6)=31.2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that math sentence as an equation:
"Negative eight times the sum of a number and 14.6 is 31.2."
Here,
-8 times (a number (sum=addition) and 14.6) = (equal to) 31.2
Therefore, the equation will be as;
-8(r+14.6)=31.2
The equation for the math sentence "Negative eight times the sum of a number and 14.6 is 31.2." will be; -8(r+14.6)=31.2
