Answer:
There are 12 golden retrievers in the park
Step-by-step explanation:
100% is 60 dogs so if 100% is equal to 60 then 20% should be the answer.
100 ÷ 5= 20
60 ÷ 5= 12
amount of dogs in the park : golden retrievers
60 : 12
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.
Answer:
2
Step-by-step explanation:
2L + 6 = 6L - 10 Add 10 to both sides
2L + 6 + 10 = 6L Combine the left.
2L + 16 = 6L Subtract 2L from both sides
16 = 6L + 2L Combine the right
16 = 8L Divide by 8
8L = 16
8L/8 = 16/8
L = 2
