6. First: make "y" a fraction, place "y" over 1...
y/1 + y/7
Sec: find the least common denominator which is 7 > multiply the missing terms to each numerator and denominator to get the least common denominator for each denominator...
7(y/1) + 1(y/7)
7y/7 + y/7
Third: add the numerators...
(7y+y)/7
8y/7
10. First: combine "like" terms...
7 + 4y = 10.2
Sec: subtract 7 from both sides (moving variables to the opposite side means the opposite sign)...
7 - 7 + 4y = 10.2 - 7
4y = 3.2
*Third: solve for "y" by isolating it on one side > divide both sides by 4...
4y/4 = 3.2/4
y = 0.8

for #6, a) find the least common denominator, which is 7 or b) think of y as 7y/7 which reduces to y, the original given.
so 7y/7 + y/7 = (7y +y)/7 or 8y/7
for #7 combine like terms, 7 + 4y = 10.2, then subtract 7 from either side, or 4y = 3.2 ; divide both sides by 4 to get rid of 4 and you get 0.8

the honestly answer is 11.7%. the honestly funding is irrelevant because the income or lack of a company is determined by the income as against the prices If we anticipate an income of one hundred for each 3 hundred and sixty 5 days and the first 3 hundred and sixty 5 days the corporation lost 10% which signifies that the prices for the corporation became better than the income by 10. as a effect 3 hundred and sixty 5 days one we've a complete cost of 100 and ten. 3 hundred and sixty 5 days 2 a income of 20% signifies that the prices were below the income so complete cost for 3 hundred and sixty 5 days 2 is 80 3 hundred and sixty 5 days 3 has a income of 25% giving a complete cost of seventy 5. The blended complete cost for the three years is 265. complete income of the three years is three hundred. the share of cost is 88.33333333333% so call it 88.3% subtract from one hundred% you get 11.7 income. Which interprets to $35.10

6) y + y/7 = 8y/7
10) 7 + y + 3y= 10.2
7 + 4y = 20
4y = 20 - 7
4y = 13
y = 13/4
