Answer: Y=-6

Step-by-step explanation: First, you want to multiply the 9 into the parentheses.

-9y-27=2y+39

Add 9y to each side.

-27=11y+39

Subtract 39 from each side.

-66=11y

Divide by 11 on each side.

Y=-6

IceJOKER [234]

Answer:

$201.99

Step-by-step explanation:

Given that:

Amount held on Monday = $61.72

Amount withdrawn on Tuesday = $57.00

Amount deposited on Thursday = $197.27

Final balance :

Amount held on Monday - Amount withdrawn on Tuesday + Amount deposited on Thursday

$61.72 - $57.00 + $197.27 = $201.99

Hence, final balance = $201.99

Answer:

Multiply the first equation by 3 and multiply the second equation by -2.

This is justified by the multiplication property of equality

Step-by-step explanation:

we have

2x+5y=7 ----> first equation

3x+4y=6 ----> second equation

step 1

Multiple the first equation by 3 both sides

3(2x+5y)=3(7) -----> by multiplication property of equality

6x+15y=21 ----> new first equation

step 2

Multiple the second equation by -2 both sides

-2(3x+4y)=-2(6)  -----> by multiplication property of equality

-6x-8y=-12 ----> new second equation

step 3

Solve the system of equations by elimination

Adds new first equation and new second equation

6x+15y=21\\-6x-8y=-12\\-------\\15y-8y=21-12\\7y=9\\y=\frac{9}{7}

Find the value of x

substitute the value of y in any equation and solve for x

6x+15y=21

6x+15(\frac{9}{7})=21

6x=21-\frac{135}{7}

6x=\frac{12}{7}

x=\frac{2}{7}

The solution is the point (\frac{2}{7},\frac{9}{7})

therefore

Multiply the first equation by 3 and multiply the second equation by -2.

This is justified by the multiplication property of equality

Here is a number machine.
Vlad [161]

Answer:

The output is 3n + 6

Step-by-step explanation:

You have to apply all of the steps in order:

Since we cannot simplify n+2, we have to write it as (n+2). Next, since we do the next step, multiply by 3. This would be 3(n+2), and if you apply the distributive property (multiply), you would get 3 * n + 2 * 3, or 3n + 6.

Answer: 3n + 6

It is false. Since you don't know what is the variable equal to. But multiplication can't be in associative property.
