Answer: check explanation
Step-by-step explanation:
Multiply both sides of equation by x(x+a)
This will get rid of those nasty fractions...cuz who likes them?
Anyways,
Now you should I think get
x(x+a)+a(ax)=a
I am pretty positive that you just distribute and solve.
You may have to factor and have to put everything as an equation set to equal=0
you try it and experiment. Sometimes you just have to try to think algebraically and creatively. Don’t get frustrated just work with it. Good luck!
Answer:
x = - 4
Step-by-step explanation:
-79 = 7x + 3(4x - 1)
-79 = 7x + 12x - 3 Distribute 3 to the paranthesis
-79 = 19x - 3 Add like terms
-76 = 19x Add 3 to both sides
- 4 = x Divide 19 to both sides
<span>If three sides are proportional their angles must be identical therefore they are always similar.</span>
Answer:
Select all the lines with slope 
.
Step-by-step explanation:
Use the slopes to help you answer this kind of questions.
The slope of the line going through: (1, - 2) and (3,4) is given by:
We plug in the coordinates to get:
All lines that are perpendicular to this line has slope .
Answer:
15
Step-by-step explanation:
To get 10 percent, you divide by 10.
150 divided by 10 equals 15.
