Answer:

21 adults and 139 children

Step-by-step explanation:

x=adult (8$)

y=child (5$)

8x + 5y =863

x+y=160

-x -x (subtract x on both sides)

y= -x + 160

plug that in for y on the other equation

8x + 5(-x + 160) =863

distribute 5 to both

8x + -5x + 800 = 863

combine both x values

3x + 800 = 863

-800 -800 (subtract on both sides)

3x = 63

divide by 3 on both sides

x = 21 adults

now plug x in one of the equations

21 + y = 160

-21 -21

y=139 children

Which equation has the least steep graph?

MAVERICK [17]

Answer:

$y=\frac{1}{4}x+6$

Step-by-step explanation:

$y=\frac{1}{4}x+6$ is the least steeped graph

The greater the slope, the steeper the line.
Also you use the absolute values of the slopes when determining the steepness.

So here it would be: $\frac{3}{4},7,\frac{1}{4},2$
Now, arrange them from least to greatest: $\frac{1}{4},\frac{3}{4},2,7$

As you can see, $\frac{1}{4}$ is the smallest number/slope.

Hope this helps!
