Solve the equation for y.

8x – 9y = 11

Answers

Answer 1
Answer:
Watch carefully:

                                             8x - 9y = 11

Add  9y  to each side:                    8x = 11 + 9y

Subtract  11  from each side:    8x - 11 = 9y

Divide each side by  9 :        y = 1/9 of (8x - 11)


Answer 2
Answer: 8x-9y=11subtract 8x from both sides-9y= -8x+11divide both sides by -9y= 8/9x-11/9hope this helps

Two equations are shown: Equation 1: (x –12) =12
Equation 2: y – 12 = 12
Solve each equation

Answers

x-12=12, x=24, 24-12=12
y-12=12 y also =24
x-12=12
x=12+12
x=24

y-12=12
y=12+12
y=24

The answer is: a=24 y=24

sonja and jake just got married. they received $4,500 in gift money and deposited it into a savings account that pays 1.85% simple interest.How much will they have in savings after 3 years?

Answers

The total amount in savings after 3 years is $ 4749.75

Solution:

Sonia and Jake received $4,500 in gift money and deposited it into a savings account that pays 1.85% simple interest

To find: Amount after 3 years

The total amount after 3 years is given as:

total amount = principal amount + simple interest

The simple interest is given as:

\text {simple interest }=\frac{\text { principal } * \text { number of years } * \text {rate of interest }}{100}

Here principal amount = $ 4500

Rate of Interest = 1.85%

Number of years = 3 years

Substituting the above values in formula we get,

\text { simple interest }=(4500 * 1.85 * 3)/(100)

\text {simple interest }=45 * 1.85 * 3=249.75

Thus simple interest = $ 249.75

total amount = principal amount + simple interest

total amount = 4500 + 249.75

total amount = $ 4749.75

Thus the total amount after 3 years is $ 4749.75

What is the ratio of 9 daises to 16 roses?

Answers

The ratio of 9 daises to 16 roses is 9:16 or also \boxed{(9)/(16)}

This cannnot be simplified any more because 9 and 16 are both perfect squares. :)
I believe it would be 9 to 16 which can also be 9 over 16 which cannot be simplified any more than it already has been hope this helps and its what you were asking for
