Answer:730
Step-by-step explanation:
Answer:
One solution is, (3,2)
One solution is, (-1,1)
There are infinitly many solutions
The equation of the line is 
Step-by-step explanation:
Anything on the line is a solution.
The line is infinite therefore the solutions are also infinite.
The dot (3,2) and (-1,1) are both on the line therefore they are both solutions.
The slope of the line is 0.25 or 1/4 so we know the first part of the equation.
y = 1/4x
The y-intercept is on the point 1.25 or 5/4
We now know the whole equation
y = 1/4x + 5/4
To double check you can plug in points into the x and y spots on the equation or as I did graph it.

Answer:
Step-by-step explanation:
a) The fraction is ...
2(5 1/4)/(15 2/3) = (21/2)/(47/3) = 63/94
Two streamers will require 63/94 of the original material.

b) $4800 is 70% of Sara's salary, so that salary is ...
4800 = 0.70s
4800/0.70 = s = 6857.14
Sara's salary is about $6857.14.
Triangle=1
Diamond=3
Hex=7
Proofs:
1+3+3=7
1+1+1=3
1+3+7=11
7-3=4*1
