Answer:

Clara's number is 42 less than Anna's number

Step-by-step explanation:

We can start this problem out by setting our variables up:

A= Anna's number

B= Boris's number

C= Clara's number

so we can use them to build our equations. We can sepparate the problem into little more understandable pieces of information, let's start with the first piece of information:

- "Ana's number increased by 20"

A+20

- "boris's number decreased by 22"

B-22

- "21 greater than boris's number decreased by 22."

(B-22)+21

- "Ana's number increased by 20 is 21 greater than boris's number decreased by 22."

A+20=(B-22)+21

This is our first important equation here. Let's go with the second part of the problem:

- "Boris's number decreased by 20"

B-20

- "claras number increased by 22"

C+22

- "21 greater than claras number increased by 22"

(C+22)+21

Now the whole thing:

"Boris's number decreased by 20 is 21 greater than claras number increased by 22."

B-20=(C+22)+21

This is our second important equation.

So now we have the following system of equations:

A+20=(B-22)+21

B-20=(C+22)+21

We can now simplify the equations by combining like terms so we get:

Equation 1:

A+20=(B-22)+21

we can get rid of the parenthesis so we get:

A+20=B-22+21

We can subtract a 20 from both sides of the equation so we get:

A=B-22+21-20

We perform the subtractions so we get:

A=B-21

Equation 2:

B-20=(C+22)+21

We get rid of the parenthesis:

B-20=C+22+21

We add a 20 to both sides so we get:

B=C+22+21+20

We can now perform the additions so we get:

B=C+63

And now we can combine the equations. In this case we can substitute equation 2 into equation 1 to get:

A=C+63-21

We combine like terms to get:

A=C+42

We can subtract 42 from both sides to get:

C=A-42

which reads:

Clara's number is 42 less than Anna's number.

Results are below.

Step-by-step explanation:

Giving the following information:

Today, average yearly tuition and fees for one year at the university are about $10,350.

I will assume a yearly interest rate of 8%.

First, we need to calculate the total amount needed:

Future value (FV)= 10,350*4= $41,400

Now, using the following formula, the annual deposit required:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (41,400*0.08) / [(1.08^15) - 1]

A= $7,194.22

Answer:

[tex]n=-24[/tex]

Step-by-step explanation:

[tex]15+n=-9[/tex]

Simplify both sides:

[tex]n+15=-9[/tex]

Subtract 15 from both sides:

[tex]n+15-15=-9-15\\n=-24[/tex]

n = -24 is your final answer!

Step-by-step explanation:

15+n=-9

n=-9-15

n=-24

=-24

Answer:

x=1

y=7

Explaination:

y=7x---------(1)* *First equation

x-7y=(-48)----(2)* *Second equation

Put (1)* into y on (2)*

x-7(7x)=(-48)

x-49x=(-48)

-48x=(-48)

48=48x

48÷48=x

1=x or x=1--------(3)* *Third equation

Put (3)* into (1)*

y=7(1)

y=7

Answer:

x = 3

Step-by-step explanation:

I will assume you meant 5 - (2/3)x = 3.  This simplifies to -(2/3)x = -2, or

(1/3)x = 1, so that x = 3.

                                                         2

"2/3x" could be interpreted as   ---------  which would give us a very different

                                                         3x                 result.  Use parentheses to

                                                                               lessen the chances of

                                                                                misinterpretation.
