Simplify the 2/4
1/2b=-1/2
Divide each side by 1/2
b = -1

An equation is 
Step-by-step explanation:
Let
be the measure of the unknown acute angle.
According to angle sum property of a triangle, sum of all the angles of a triangle is equal to 180°.
One of the acute angles of a right triangle is equal to 52°.
Also, the triangle is a right angled triangle, one of the angle must be equal to 90°.

So, an equation is 
Answer:
648
Step-by-step explanation:
A=Ph
P=perimeter of triangle
P=6+6+6
P=18
h= height of prism
h=38
A=ph
A=18*36
A=648
<span>40 <= x =<100 inequality shows the right answer.
Explanation:-
Since she has to reach the $200 mark by selling cakes at the rate of $5 each.
So, the minimum number of cakes should be 200/5 which is equals to 40.
Hence minimum value of number of cakes (x) = 40
It is given that She has 100 cakes this implies that maximum value of x can be 100.
hence X can be any value between 40 to 100 both inclusive.</span>
