Let x be the number of square feet to be mowed
215 square feet take 22 minutes
x square feet take 12 minutes
Answer:
9
Step-by-step explanation:
If you add 9 to both sides, you will isolate the 'x' term.
hope this helps :)
Answer:
B is correct
Step-by-step explanation: an infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
The standard form: Ax + By = C.
We have:
<h3>Answer: x - 4y = 8</h3>
Answer:
x=18
Step-by-step explanation:
set up the equation:
DBC+DBC=ABC
79+79=(9x-4)
Simplify both sides of the equation.
79+79=9x−4
79+79=9x+−4
(79+79)=9x−4(Combine Like Terms)
158=9x−4
158=9x−4
Flip the equation.
9x−4=158
Add 4 to both sides.
9x−4+4=158+4
9x=162
Divide both sides by 9.
9x
/9 = 162
/9
x=18
