if Noah needed 20 pictures in all ,but only had 11 he would subtract 11 from 20 leaving Noah with 9 pictures.
Answer:
length = 15
breadth = 25
Step-by-step explanation:
length = breadth + 10
let length be x
length = x
breadth = x + 10
perimeter = 2(length) + 2(breadth)
80 = 2(x) + 2(x + 10)
80 = 2x + 2x + 20
80 = 4x + 20
80 - 20 = 4x
60 = 4x
15 = x
length = x = 15
breadth = x + 10 = 25
<h3>
Answer:</h3>
infinite solutions
<h3>
Step-by-step explanation:</h3>
Add the two equations.
... (-4x) + (y) = (y +3) +(-4x -3)
Add 4x -y to both sides.
... -4x +y +4x -y = -4x +y +4x -y
... 0 = 0 . . . . . true for all values of x (or y)
Both equations describe the same line.
_____
The graph shows the first equation as a red line. The second equation is shown using a "blue dot" texture, so you can see it overlays the red line.
