the 1st one is the right answer.
<span>1. System of equations</span>
Well, the definition of a system of linear equations is: Any equation that can be written in the form Ax + By = C. ... The System of equations is a set of equations with the same variables is a system of equations.1. ... Solve the newer equation, then substitute the value found into any equation involving both variables and solve for the other variable. ... To sum up this paper, There are three types of systems of equations. There is 3 ways to algebraically solve systems of equations
Answer:B
Step-by-step explanation:
Answer:
Part A - 2/5 of a dollar
Part B - It shows that 10 pounds of cabbage cost $4
Step-by-step explanation:
If 5 pounds cost $2 then 1 pound costs 2/5 of a dollar.
(10,4) - 10 is the x-axis which is pounds and 4 is the y-axis which is $. So 10 pounds cost $4.
To round a number, you first have to determine what you are rounding to. in this case, it's the nearest dollar. Then, you determine whether to "round up," to the next higher number, or "round down," which is to stay at the number it's currently at, without the numbers following what you're rounding to. If the number after the place you're rounding to is equal to or higher than 5, you'll round up. If it's lower, you'll round down.
So, for your questions, the answers would look like this:
$8.98 rounds to $9.00, because 9 is bigger than 5.
$6.49 would round down to $6.00, because 4 is less than 5.
$2.51 rounds up to $3.00, because 5 is equal to 5.
$9.78 would round up to $10.00, because 7 is higher than 5.
$39.89 will round up to $40.00, because 8 is bigger than 5.
