The 2 expressions: 10x + 100 and 20x + 20
20x + 20:
20 dollars per visit (20x) ; 20 dollar fee (20)
10x + 100 = 20x + 20 Subtract 10x from both sides
100 = 10x + 20 Subtract 20 from each side
80 = 10x Divide by 10

And empty propane tank weighs 17 pounds. A full propane tank weighs 37 pounds. If propane tank weighs 35 pounds what percentage the propane remains in the tank?
Answer: 5.4054%. Based on the given conditions, formulate: 37 - 35 / 37 Calculate the sum or difference: 2/37
The percentage of the propane that remains in the tank is 94.59%.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that an empty propane tank weighs 17 pounds. A full propane tank weighs 37 pounds. Initially the propane tank weighs 35 pounds.
Let the total capacity of the tank be {x}.
For {x} = 0%, y = 17
For {x} = 100%, y = 37
Now,
100% of the filled tank weighs 37 pounds.
1 pound of the tank will be filled by : (100/37)% of propane
35 pounds of the tank will be filled by : {(100/37) x 35}% of propane
{(100/37) x 35}%
3500/37
94.59%
Therefore, the percentage of the propane that remains in the tank is 94.59%.

convert the following equation into standard form.
y = -3x/5 + 4 halp
Answer:
3x+5y=20
Step-by-step explanation:
Answer:
3x + 5y = 20
Step-by-step explanation:
The given y = -3x/5 + 4 is in slope-intercept form. We are to put it into standard form, which would be Ax + By = C.
Start by eliminating the fraction representing the slope (-3/5); to do this, multiply all three terms by 5:
5y = -3x + 20
Next, rearrange the terms to resemble Ax + By = C:
3x + 5y = 20

Pablo has ten dollars. He wants to buy 7 packs of gum. Rach pack of gum costs $1.50. Does he have enough? How do you know?
Answer:
no. it costs $10.5
Step-by-step explanation: first you multiply 1.5 ( how much it costs) by 7 ( how much hes gonna get) and that equals 10.5. as you can see, thats 5 cents more than 10 dollars
Answer:
No, he does not have enough. Here's why.
Step-by-step explanation:
Pablo has 10 dollars, and each pack of gum costs $1.50. He wants 7 packs, so we do $1.50 times 7(for 7 packs.)
$1.50 times 7 is $10.50, which leaves Pablo 50 cents short.
He does not have enough money.

Which point has coordinates (−2, 1.5) ?
A
B
C
I don't know.
A coordinate grid with the x and y axis from negative 3 to 3, with each line on the graph representing a step of 1 fourth. Point A is 8 steps to the right and 6 steps up. Point B is 8 steps to the left and 6 points up. Point C is 6 steps to the left and 1 step up.
Point B. is 8 steps to the left and 6 points up has coordinate points (-2,1.5).
What is a coordinate grid?A coordinate grid is a plane in which we can graph 2D figures.
If we assume that each square box n the x-y plane is of 1 sq unit then the length of the sides of each box is 1 unit.
Now we can observe that 4 such sides or boxes have a value of 1 unit so we can say that the plane has been shrunk by a factor of 1/4.
If we observe point B which is 8 steps to the left and 6 points up we can conclude B( -8,6) and has a scale factor of (1/4).
∴ B(-2,1.5).

Backtracking: what is the opposite operation used to solve for X?
A multiply by 12
B multiply by 60
C Divide by 12
D Divide by 60
Step-by-step explanation:
since the operation to solve for x is to divide both sides by 12, the opposite is multiplying by 12.
so, A is the correct answer.
Answer:
C) divide by 12
Step-by-step explanation:
'x' and 12 are getting multiplied
so to isolate 'x' you must do the inverse operation of multiplication, which is division
then you have x = 60/12 or x = 5

Which of these is a formula that can be used to determine the nth term of the arithmetic sequence 15, 27 39 51
Answer:
an=3+12n
Step-by-step explanation:
The sequence is
15, 27, 39, 51
The first term: a 1 = 15
The common difference of this sequence : d = 27 − 15 = 12
The nth term of an arithmetic sequence is given by formula
an=a+(n−1)d
So a n for this sequence will be:
an = 15 +(n−1) 12
an =(15)+12n−12
an = 3+12n
