Hey there!
This seems like a
algebraic expression
SO,
Remember: negative and negative =
positive positive and positive =
positive positive and negative =
negative negative and positive =
negative
In
this problem we will be doing
negative and negative so that means our answer will be
a negative
Firstly, lets line up our decimals to solve this problem (once when you do that , you can solve it easier)

Answer: 
Good luck on your assignment and enjoy your day

3+7 = 10
You do 500/10 which is 50 to find out 1
1 = 50
3 = 50 x 3 = 150
7 = 50 x 7 = 350
The ratio is 150 : 350
70a + 55b = 905
a + b = 14
55a + 55b = 770
(70a-55a) + (55b-55b) = 905 - 770
15a = 135
a = 9
a + b = 14
9 + b = 14
b = 5
Answer:
A quadrilateral and parallelogram
Step-by-step explanation:
For this case we have that by definition, the slope point equation of a line is given by:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
By definition, if two lines are perpendicular, the product of their slopes is -1. That is to say:

Substituting:

We substitute the point to find "b":

Finally:

Answer:
