Select from the choices below, dragging and dropping to build an inequality that could be used to determine when Martin's comic book
collection exceeds Beth's
Answer:
The answer to your question is 250 - 20 < 80 + 15x
Step-by-step explanation:
Data
Beth has 250 books and sells 20 each week
Martin has 80 books and sells 15 each week
week = x
Process
1.- Write an equation for each situation
Beth 250 - 20x
Martin 80 + 15 x
2.- Write the inequality
250 - 20 < 80 + 15x
7x + 6y = 31
The solution is, (1,4) is the solution of the system of equations and choose the correct ordered pair.
4x + 3y = 16
7x + 6y = 31
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
given that,
equation: 1
4x+3y=16
y=(16-4x)/3
equation: 2
7x+6y=31
y=(31-7x)/6
now, we have,
(16-4x)/3 = (31-7x)/6
6(16-4x) = 3(31-7x)
96-24x=93-21x
3=3x
x=1
we get,
4x+3y=16, x=1
4(1)+3y=16
4+3y=16
3y=12
y=4
so, we have,
x=1, y=4
therefore the answer is B (1,4)

if there is a way to give medals can someone tell me I will medal you for answering this.
Solve for the following equation step by step and justify your steps when using an exponential property.
(7^x)^4= 7^2*7^3/7^x3
Answer:
(7^x)^4 = (7^2 * 7^3)/7^3x
7^4x = 7^5/7^3x
7^4x = 7^5-3x
4x = 5 - 3x
7x = 5
x = 5/7
