Answer:
Midpoint={5.5,1}
Step-by-step explanation:
M={x1+x2/2,y1+y2/2}
M={6+5/2,-2+4/2}
M={11/2,2/2}
M={5.5,1}
They rented out 5 self-propelled mowers and 20 riding mowers.
Data;
- Total number of tool rented out = 25
- Cost of tools rented = $900
<h3>System of Equations</h3>
To solve this problem, we have to write a system of equations to represent the problem.
since we have
- x = self - propelled mower
- y = riding mowers
Let's write equations with these variables.

From equation (i)

Put equation (iii) into equation (ii)

Let's substitute the value of y into equation(i)

From the calculations above, they rented 5 self-propelled mowers and 20 riding mowers.

Answer:A
Step-by-step explanation:
0=-2x^2+x+3
-2x^2+x+3=0
a=-2 b=1 c=3
here we have 3X to 5 seventh power in radical form

we need write this in radical form we knwo that 
so ![3x^{5/7} =\sqrt[7]{3x^{5}}](https://tex.z-dn.net/?f=%203x%5E%7B5%2F7%7D%20%3D%5Csqrt%5B7%5D%7B3x%5E%7B5%7D%7D%20%20%20)
this will be the radical form .
A/2-b/3=1 solve for a, add b/3 to both sides
a/2=1+b/3 which is equal to
a/2=(3+b)/3 multiply both sides by 2
a=(6+2b)/3 now you can substitute this into 2a+3b giving you:
2(6+2b)/3 + 3b which is equal to
(12+4b+9b)/3
(13b+12)/3
