Answer:
x=-11/8
Step-by-step explanation:
x-(5/8)=-2
Give the -2 a common denominator to make it easy
x-(5/8)= -16/8
Add the 5/8 to the -16/8
x= -11/8
That equation has no solution. There is no number that can be written in place of 'x' that makes the equation true.
First thing to do is solve the given equation for v
-11v-7 = 4
-11v = 4+7
-11v = 11
v = 11/(-11)
v = -1
Once we know this, we can use it to compute the following
7v-10 = 7*(-1) - 10 = -7 - 10 = -17
--------------------------------
Answer: -17
Answer:
b=2a/h
Step-by-step explanation:
So there are two triangles here: Smaller one (ADE) and bigger one (ABC) and they both are similar.
So you can use proportions here.
AB / AC = AD / AE
AB = AD + DB = 6 + 1 = 7
AC = AE + 3
AD = 6
So plug in these values:
AB / AC = AD / AE becomes
7 / (AE + 3) = 6 / AE
Now do the cross multiply:
7 AE = 6 (AE + 3)
Now solve for AE:
7AE = 6AE + 18
AE = 18
