Answer: b) multiply row 1 by -3 and add the result to row 2
Step-by-step explanation:
Answer:
GCF: 2
Step-by-step explanation:
GCF: 2
(2*16) + (2*27)
Assume the sum is 100. The ratio of the two numbers is 15:10. This means that we can divide this indow 15+10, or 25 parts. Let us do that. Divide 100 into 25 parts and see how much is in each part. 100/25 is 4, meaning that there is 4 in each part. 15 parts will have 15*4, or 60. 10 parts will have 10*4, or 40. To confirm, add 40 and 60. It matches with what we started out with, 100.
The two numbers, assuming the sum is 100, are 40 and 60. 60 is the greater value.
The answer t your question is option c because you have to expand the brackets
12=2x-1
Move negative one to the other side as a positive number
13=2x
Divide both sides by two
13/2 is option c
The slope can be found using rise over run
the line goes up 5 and over 10
so the slope would be 5/10 or 1/2
therefore the equation of the line is:
y=1/2x
