Answer: (-1,2)
Steps:
Solve by elimination
Multiply the first equation by 2 to make the coefficients of x in both equations the same
2(x+2y=3)
2x+4y=6
Then line them up and subtract
2x+y=0
-2x+4y=6
= -3y=-6
Divide both sides by -3 to isolate y
y=2
Then substitute 2 for y into one of the equations to find x.
x+2(2)=3
x+4=3
x=-1
It is 16 because you multiply 4 and 4 you get 16 from that square feet

Answer for ed2020
C.) The perimeter of the rectangle is (10x + 18) units.
Step-by-step explanation:
To figure this out, we need to use fractional proportions.
Currently, we have $120, the amount earned, and 2 days, the current rate.
Our fraction for this is: 120 / 2 = x / 6, x being the amount earned in 6 days.
Let's use a little technique to help us answer faster.
With our current money earned, 120, and our current days, 2, we can divide 120 by 2 to find out how many we earned in 1 day.
120 / 2 = 60.
We earned $60 per day.
With this formula, 60d, d being the amount of days, we can solve quicker.
We are solving for 6 days, so multiply $60 by 6 days.
60 x 6 = 360
Your proportion is :
120/2 : 360/6
I hope this helps!
