Answer:

x=1

Step-by-step explanation:

To solve, we need to get x by itself. To do this, preform the opposite of what is being done to the equation, and everything that is done to one side, must be done to the other.

5(2x-8)+15= -15

First, subtract 15 from both sides, since 15 is being added

5(2x-8)+15-15=-15-15

5(2x-8)=-30

Next, divide both sides by 5 since 5 is being multiplied

5(2x-8)/5= -30/5

2x-8= -6

Add 8 to both sides, since 8 is being subtracted

2x-8+8= -6+8

2x= 2

Divide both sides by 2, since 2 is being multiplied

2x/2= 2/2

x=1

Answer:

x=1

Step-by-step explanation:

5(2x-8)+15=-15

first do what is in parentheses, multiply the 5 with 2x and -8.

10x-40+15=-15

add 15 to -40

10x-25=-15

add 25 to both sides

10x=10

divide 10 on both sides

x=1

In the 1980s an average mortgage rate was around 18.5 how much less per month would a 150000 30 year mortgage by today if the cu
lianna [129]

Answer:

  $1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

  A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

  A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.

Which expression has the same value as 5(4x+4)
aev [14]

Answer: 20x + 20

Step-by-step explanation: In this problem, the 5 "distributes" through the parentheses, multiplying by each of the terms inside.

So we have 5(4x) + 5(4) which simplifies to 20x + 20.

Yuliya22 [10]

Answer:

False

Step-by-step explanation:

Correlation measures the strength of the relation between two variables.

Further, Correlation is said to be positive if increasing/decreasing the one variable, also increases/decreases the values of another variable.

Correlation is said to be negative if increasing/decreasing the one variable, also decreases/increases the values of another variable.

Since we don't know here exists a positive correlation or negative correlation.

So here are two possible conditions:

The person who has Gum disease also has heart disease.

And, the person has Gum disease can never have heart disease.

Thus, the given statement is false.
