Answer: x = 2/7y + 3/7 and
x= -5/4y + 0.8125
Step-by-step explanation: Let's solve for x.
7x−2y=3
Step 1: Add 2y to both sides.
7x − 2y + 2y= 3 + 2y
7x = 2y + 3
Step 2: Divide both sides by 7.
7x/7 = 2y+3/7 this is for the second answer Step 1: Add -5y to both sides.
4x+5y+−5y=3.25+−5y
4x=−5y+3.25
Step 2: Divide both sides by
4/4 x 4 = −5y + 3.25/4
Answer:
17.74
Step-by-step explanation:
The fraction is easily converted to one with a denominator of 100 (a power of 10):
Then the number of interest is ...
17 37/50 = 17 74/100 = 17.74
Answer:
The time is independent of the months we multiply these minutes as grouping with subject impression or importance. This way within the frequency you can see 263340 represents what score you are looking for importance ie) 20/20 for your book choice. This is 8 days which fits better for a monthly review 8,8,8 and 6. Which would easily be readable in the minute totals.
240= 8 nights 180 minutes = 6 nights. Having a frequency helps determine patterns for book interest and study.
Step-by-step explanation:
Subjects (imp) Minutes (M P/D) F(Frequency)
score 1-3 30 60
4-6 60 300
7-9 60 420
10-12 90 990
Total 26 + 240 ...266 x990 = 263340
The slope is -4/3 because it's the coefficient of x
