Answer:
B
Step-by-step explanation:
The formula for the area of a triangle is given as:
A = ½*base*height
A = ½*b*h
A = (bh)2
If we know the area (A) and the base, to find the height, the following would be done:
Divide both sides by b
A/b = h/2
Multiply both sides by 2

As we can see here, to find the base, we would divide the area by the vase, then multiply what we get by 2.
ANSWER:
- [ 12 / ( x - y ) ]
STEP-BY-STEP EXPLANATION:
= 12 / ( y - x )
= 12 / - ( x - y )
= - [ 12 / ( x - y ) ]

You can use a porportion to solve.
(cross multiply and solve)
Answer:
.5
Step-by-step explanation:
1 Divided by 2 is .5 or 1/2
Well, I don't really understand if it is 30 or 305 because of the spacing but I'll answer both. If it is 5y+305, just divide the whole equation by 5 and it will look like this (<u>5y+305)</u> then the factor would be 5(y+61)<u>
</u> 5
If it is 5y+30 it would be just in the same process, Divide the equation by 5 and the result will be 5(y+6).
