Answer:
(8) and
(9) and
(10) and
Step-by-step explanation:
Given [Missing from the question]
Required
Write a system of linear equations
The solutions to this question is open and have different solutions
Solving (8) (-6,-2)
Let the equations be: x + y and 2x - y
--- (1)
-- (2)
So, the equations are:
and
Solving (9) (-12, 18)
Let the equations be: 3x - y and 4x + y
So, the equations are:
and
Solving (9): (2,0)
Let the equations be: x + y and x - y
So, the equations are:
and
15 tickets are yours.
250 * .06 = 15
You move the decimal point 2 places to the left because .6 is 60% instead of 6%
You just multiply the x value by 5
-2(5)=-10
-1(5)=-5
0(5)=0
3(5)=15
6(5)=30
9(5)=45

Right answer:24
</h2>
In an algebraic expression, the coefficient is <u>the number that multiplies the variable</u>. Note that if this coefficient is one (1) it is omitted.
In the case of this algebraic expression with two terms:
24x+(25)(4.5)=24x+112.5
-The first term is 24x
-and the second term is 112.5.
The variable is x (which is the value that has to be found) and 24 is the number that multiplies the variable, hence it is the coefficient.
