Answer: 20%
Step-by-step explanation: The first step in finding how much the quantity decreased. We do a subtraction:
and now we must know how much percentage is 16 of 80, for this we divide:
and finally we convert this decimal value to a percentage multiplying by 100%
0.2(100%) = 20%
the quantity decreased by 20%
Joel opened a checking account. His bank charges him a service fee of $4.95
each month. Assume y = total cost of having the account and x = number of months.
Three more than twice a number x is 15. Determine the value of x.
Answer:
Pretty sure the answer would be x=6
Step-by-step explanation:
The number (x) in: "3 more than twice a number is 15" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.
To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15
Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 3 = 15
2x + 3 - 3 = 15 - 3
2x = 12
2x/2 = 12/2
x = 6

What is the slope, Please help ASAP
Answer:
rise over run
Step-by-step explanation:
answer
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.

-1=3x-2
-3x=9
-10=-5x
Answers are in bold:
-1=3x-2
add 2 to both sides
-1+2=3x-2+2
1=3x
divide both sides by 3
1÷3=3x÷3
1/3=x
-3x=9
divide both sides by -3
-3x÷-3=9÷-3
x=-3
-10=-5x
divide both sides by -5
-10÷-5=-5x÷-5
2=x

First find the perdendicular slope (flip and change sign) : m= -[tex]\frac{1}{4}[/tex]Then set up your equation using the given ordered paired to find your y-intersept: -1 = -[tex]\frac{1}{4}[/tex] (5) + bCaluclate the product: -1 = -[tex]\frac{5}{4}[/tex] + bMove the variable to the left-hand side and change its sign : -b - 1 = -[tex]\frac{5}{4}[/tex]Calculate the sum: -b = - [tex]\frac{1}{4}[/tex]Change the sign : b= [tex]\frac{1}{4}[/tex]Use the slope and y-intersept to creat the equation: y = -[tex]\frac{1}{4}[/tex]x + [tex]\frac{1}{4}[/tex]A house costs $18,000, which is 9/10 the cost of a car.

Average ant weight 4x10^-3 grams. Ant population is 10,000 trillion (10,000,000,000,000,000). What is the total mass of all ants? Show work for mass of ants (grams):
Answer:
The total mass is 4 * 10^12 grams
Step-by-step explanation:
To get the total mass of all ants,
We simply multiply the average mass of an ant by the population
That will be;
4 * 10^-3 * 10^15
= 4 * 10^12 grams

Using the two given points, you can find the slope by finding the difference in the y coordinates and diving it by the difference in the x coordinates.
y coordinates: -3 - 5= -8
x coordinates; 2-(-2) = 4
Slope: -8/ 4 = -2

What is the solution to this system of linear equations?
2x + y = 1
3x – y = –6
(–1, 3)
(1, –1)
(2, 3)
(5, 0)
x = -1
y = 3
2x + y = 1 (eq no 1)
3x - y = -6 (eq no 2)
solve eq no 1
y = 1 - 2x (eq no 3)
enter eq no 3 into eq no 2
3x - ( 1 - 2x ) = -6
3x - 1 + 2x = -6
5x = -5
x = -5/5
x = -1
enter x = -1 into eq no 1
2 (-1) + y = 1
-2 + y = 1
y = 3
