Answer:
21 monkeys
Work:
The ratio is 3:7 so 3*3=9 lions 7*3=21 monkeys
9+21=30
8 goes into 72 and 8
72÷8=9
8÷8=1
Answer:
Infinitely many solutions.
Step-by-step explanation:
Given
![y = -\frac{10}{7}x + \frac{2}{9}](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B10%7D%7B7%7Dx%20%2B%20%5Cfrac%7B2%7D%7B9%7D)
![y = -\frac{10}{7}x + \frac{2}{9}](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B10%7D%7B7%7Dx%20%2B%20%5Cfrac%7B2%7D%7B9%7D)
Required
Number of solutions
Substitute
in the second equation
![-\frac{10}{7}x + \frac{2}{9} = -\frac{10}{7}x + \frac{2}{9}](https://tex.z-dn.net/?f=-%5Cfrac%7B10%7D%7B7%7Dx%20%2B%20%5Cfrac%7B2%7D%7B9%7D%20%3D%20-%5Cfrac%7B10%7D%7B7%7Dx%20%2B%20%5Cfrac%7B2%7D%7B9%7D)
Add
to both sides
![\frac{10}{7}x -\frac{10}{7}x + \frac{2}{9} = \frac{10}{7}x -\frac{10}{7}x + \frac{2}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B7%7Dx%20-%5Cfrac%7B10%7D%7B7%7Dx%20%2B%20%5Cfrac%7B2%7D%7B9%7D%20%3D%20%5Cfrac%7B10%7D%7B7%7Dx%20-%5Cfrac%7B10%7D%7B7%7Dx%20%2B%20%5Cfrac%7B2%7D%7B9%7D)
![\frac{2}{9} = \frac{2}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B9%7D%20%3D%20%5Cfrac%7B2%7D%7B9%7D)
<em>The above solution implies that, the equations have infinitely many solutions.</em>
Answer:
24.4 cm
Step-by-step explanation:
2.
s = 6.1 cm
P = 4s = 4(6.1 cm) = 24.4 cm
Answer: 24.4 cm
Answer:
It would be (-2,11)
Step-by-step explanation:
I used desmos for this, since it says graphing.
desmos.com/calculator/glijhd4ksg
look at the link to view the graph and solution.
Normally, you would plot points from one line, connect them, then do the same for the other line.
Hope this helps!
