Answer:

x = 16

Step-by-step explanation:

From the first statement, we can say that:

Angle A is equal to angle D,

Angle B is equal to and E.

Since measure of Angle B and E are given and they are equal, we equate them and solve for x.

B=E\\x+15=6x-65\\15+65=6x-x\\80=5x\\x=\frac{80}{5}\\x=16

Hence x = 16

After you add both sides by 9. How can you solve for 5z in this equation?
antiseptic1488 [7]

Answer:

<u>The correct answer is A. Divide both sides by positive 5</u>

Step-by-step explanation:

Let's solve the equation for finding z and the necessary steps to do it:

5z - 3 = 12

5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)

5z = 15 (Adding 12 plus 3 at the right side)

5z/5 = 15/5 (Dividing by positive 5 at both sides)

<u>z = 3</u>

<u>The correct answer is A. Divide both sides by positive 5</u>

Amy opened a savings account with $1750 she received for graduation. The account pays 4.3% simple interest. What is the balance
Cerrena [4.2K]

Given:

  • The principal amount that Amy opened her savings account with is $1750.
  • The rate of simple interest compounded annually is 4.3%.
  • The time period for which we calculate the new balance is 6 months.

To Find:

The balance after 6 months.

Answer:

The balance after 6 months will be $1787.625

Step-by-step explanation:

The principal amount that Amy opened her savings account with is $1750. We can denote this by P.

The rate of simple interest compounded annually is 4.3% which we may denote by R.

The time period for which we calculate the new balance is 6 months which can be written as 0.5 years (since the rate of interest is compounded annually, we must consider the time period in terms of years).

The amount of money accrued from the interest can be calculated by the formula

\frac{PRT}{100}

Putting in the values given in the question, we have

\frac{(1750)(4.3)(0.5)}{100} = 37.625

The amount in the bank account will be the principal amount plus the amount of interest accrued that we have calculated above.

Thus, the balance after 6 months will be 1750 + 37.625 = $1787.625.

Can you show me the full formula i will reward you with 10 points​
Papessa [141]

Answer:

The formula is 4x+3x+2x=180.

x= 20

a= 40

b= 80

c= 60

Step-by-step explanation:

The expression is the angle measurments equaled to 180 degrees because they all make up a straight line (180 degrees).

You then find the other angle measurments by identifying the verticle angles.

For example, 3x= 60 degrees. Therefore angle C= 60 because it is verticle to 3x
