Simplify by combining like terms to
-n+4=8n-5
subtract 8n from both sides
-n+4-8n=8n-5-8n
-9n+4=-5
subtract 4 from both sides
-9n+4-4=-5-4
-9n=-9
Divide both sides by -9
-9n/-9=-9/-9
n=1
hope this helps!
Answer: No real solution
Step-by-step explanation:
<h3>
Answer: 64 cm^2</h3>
Reason:
The parallelogram has area of A = base*height = 10*7 = 70 cm^2
The white rectangle has area of B = base*height = 3*2 = 6 cm^2
The shaded region has area of A - B = 70 - 6 = 64 cm^2
If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
Because both equations are equal to y, you can set the equations equal to each other.
2x+5= x+3
-x -x
x+5=3
-5 -5
x= -2
Then, you can substitute -2 to any equation to find x.
y= (-2)+3 y= 2(-2)+5
y= 1 y= -4+5
y=1
:
x=-2
y=1
