Answer: 20 parks
Step-by-step explanation:
Let the total number of parks be y.
Then 75% of y = 15 , that is
x y = 15
75y = 15 x 100
75y = 1500
divide through by 75
y = 1500/15
y = 20
Therefore Springfield have 20 parks altogether
To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2
to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
Yes;what's your question?
You would subtract 3x from the left side, and get -2 = -2x, so x=1 would be your answer
