We will have a system of equations, and we are going to solve it by using substitution.
Let's make the equations.
x+y+z=2100
z+y=x
Since y and z are equal, I think it is easier for us to have them as one variable for now. Let the value of z and y be a.
These are the equations now.
x+2a=2100
2a=x
Since the second equation is giving the value of x, let it replace the value of x also in the first equation.
2a+2a=2100
4a=2100
2100÷4= 525
so, x and y equal 525. Let's put this in our original equation.
x+525+525=2100
x+ 1,050= 2,100
x= 1,050
So, x=1,050, y= 525 =z.
The rate is 12! why Well easy if you divide 72 by 6 is 12
Step-by-step explanation: 1. Distibute the + (if there is no number after it, it means 1), so -17+43-5. 2. Then you just solve from left to right
Answer:
k/11 =7
Step-by-step explanation:
k divided by 11 is 7
k/11 =7
Multiply each side by 11
k/11*11 = 7*11
k = 77
8 pages per 1 minute
so 136 pages will be 136/8 = 17 minutes
Will take 17 minutes to print out 136 pages
