y=6

Step-by-step explanation:

75 - 3.5y - 4y = 4y + 6

Collect like terms and simplify

- 3.5y + 4y - 4y = 6 - 75 \\  - 11.5y =  - 69

Divide both sides of the equation by-3.5

\frac{ - 11.5y}{ -11.5}  =  \frac{ - 69}{ - 11.5}

Simplify

y = 6

Answer:

y = 6

Step-by-step explanation:

Add like terms: 75 - 7.5y = 4y +6

subtract 6 from both sides: 69 - 7.5y = 4y

add 7.5y to both sides: 69 = 11.5y

divide both sides by 11.5: 6 = y

grin007 [14]
Add whole numbers: 2 + 6 + 8 = 16
Add fractions:

= 1/3 + 3/4 + 1/2

= (8 + 18 + 12) ÷ 24

= 38/24 or 1 14/24 or simplified to 1 7/12

Total surface area = 16 + 1 7/12 or 17 7/12

Merle Fonda opened a new savings account. She deposited $40,000 at 10% compounded semiannually. At the start of the fourth year,
IrinaVladis [17]
Use compound interest formula  F=P(1+i)^n twice, one for each deposit and sum the two results.

For the P=$40,000 deposit,
i=10%/2=5%  (semi-annual)
number of periods (6 months), n = 6*2 = 12
Future value (at end of year 6),
F = P(1+i)^n = 40,000(1+0.05)^12 = $71834.253

For the P=20000, deposited at the START of the fourth year, which is the same as the end of the third year.
i=5% (semi-annual
n=2*(6-3), n = 6 
Future value (at end of year 6)
F=P(1+i)^n = 20000(1+0.05)^6 = 26801.913

Total amount after 6 years
= 71834.253 + 26801.913
=98636.17   (to the nearest cent.)
