Answer:
a=-2
We move all terms to the left:
2(2a+3)-6-(5a+2)=0
We multiply parentheses
4a-(5a+2)+6-6=0
We get rid of parentheses
4a-5a-2+6-6=0
We add all the numbers together, and all the variables
-1a-2=0
We move all terms containing a to the left, all other terms to the right
-a=2
a=2/-1
a=-2

Put each variable's value in parentheses:
P = 2(2.5) + 2(3 2/5)
Solve and get P = 5 + 6 4/5 which as 11 4/5.
The mixed number answer is 11 4/5
3/5 = ?/300
We multiply 5 by 60 to get 300
So you do the same to 3
3x60= 180
180
Answer:
-7, 5
Step-by-step explanation:
Leg CB = x and leg DE = y - 1. Becuase of the markings on the triangles, we know that CB = DE; therefore, x = y - 1. So let's use that x value when we set the 2 hypotenuses equal to each other. Before any substition, 3x - 2 = 2y + 1. Subbing in for x we have 3(y - 1) - 2 = 2y + 1. And 3y - 3 - 2 = 2y + 1. Combining like terms we have y = 6. If y = 6, we will sub it into the leg equation to find x. x = y - 1; therefore, x = 6 - 1 and x = 5. There you go! x = 5 and y = 6
