A) -6a = 36
Divide both sides by -6 so that (a) is isolated.
a = -6
Check by plugging in -6 for a.
-6a=36
-6(-6)=36
36=36
So, a=-6
B) -9d=-72
Divide both sides by -9.
d = -72/-9
d = 8
Check work by plugging in 8 for d.
-9d=-72
-9(8)=-72
-72=-72
So, d=8

Step-by-step explanation:
the area of a triangle is
baseline × height / 2
in our case we have a baseline with its associated height right there. and so the area is
17 × 6 / 2 = 17 × 3 = 51 ft²
Answer: If you're looking for the sum of the equation, it's 9.57.
If you're looking for a better way to add it. It's this. (1.7 + 5.3) + 2.57.
Step-by-step explanation: The reason for my answer is quite simple. Since 1.7 and 5.3 add up to 7, all you need to do is add 7 and 2.57. That way, it's much easier to get the answer 9.57

Answer:
It is a solution
Step-by-step explanation:
8d+6= -8d-186
Add 8d to each side
8d+8d+6= -8d+8d-186
16d +6 = -186
Subtract 6 from each side
16d +6-6 = -186 -6
16d = -192
Divide each side by 16
16d/16 = -192/16
d = -12
You need to get x= something.
To do this, you -4 on both sides to leave you with just an x value on the left. This gives -6x=-6
Then you need x on its own, so you divide both sides by -6.
-6/-6= 1, so x=1
