Answer:
y = 
Step-by-step explanation:
27y + 5 = -9 -> subtract -9 and 5
(-9) - 5 = -14
27y = -14 divide 27 and -14
(-14)/27
You are then left with
y = 
Answer:
x=0, y=8. (0, 8).
Step-by-step explanation:
-6x+y=8
5x+y=8
-----------
-6x+y=8
-(5x+y)=-8
--------------
-6x+y=8
-5x-y=-8
-------------
-11x=0
x=0/-11
x=0
5(0)+y=8
0+y=8
y=8-0
y=8
Using proportions, it is found that $55.7 billion was donated to educational organizations.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:
A = 0.15 x 371 = $55.7 billion.
Hence $55.7 billion was donated to educational organizations.
