Answer: 19.08 = x + 12.25 is the equation.
$6.83 is the cost.
Step-by-step explanation: Solve for x in the equation to find the total cost of the cat food.
19.08 = x + 12.25 (All you're doing is subtracting 12.25 from 19.08)
6.83 = x
Answer:
In addition, from the response shown, using a graphical calculator brings the following benefits:
1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.
2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.
3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.
Step-by-step explanation:
Answer:
40%
Step-by-step explanation:
% of students drive to school
= no of students who drive/ total students× 100
=250/250+375×100
=250/625×100
=40%
Let the amount that the boys sold be x, the amount that girls sold will be 3x. The total will be given by:
x+3x=180
4x=180
solving for x we get:
x=180/4
x=45
Thus, boys sold $45, the girls provided 45*3=$135
