Answer:

30 and 6

Step-by-step explanation:

Given that R is the midpoint of QS , then

RS = QR , that is

5x = 3x + 6 ( subtract 3x from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

QS = QR + RS

     = 3x + 6 + 5x

     = 8x + 6

     = 8(3) + 6

     = 24 + 6

     = 30

------------------------------------------------------------------

Similarly

QR = RS , that is

6x - 9 = 2x - 1 ( subtract 2x from both sides )

4x - 9 = - 1 ( add 9 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Then

QS = QR + RS

      = 6x - 9 + 2x - 1

      = 8x - 10

      = 8(2) - 10

      = 16 - 10

      = 6

June has a savings account with an annual simple interest rate of 2.6%. She hopes to gain $6,500 in interest over a period of el
leonid [27]
\bf \qquad \textit{Simple Interest Earned}\\\\&#10;I = Prt\qquad &#10;\begin{cases}&#10;I=\textit{interest earned}\to &\$6500\\&#10;P=\textit{original amount deposited}\\&#10;r=rate\to 2.6\%\to \frac{2.6}{100}\to &0.026\\&#10;t=years\to &3&#10;\end{cases}

she should have invested P, in order to get I = 6500

but she instead invested 17,801, how much more did she need? well, P - 17801

solve for P

Solve the following Systems of Equations by Substitution or Elimination
Likurg_2 [28]

Answer:

(-1,2)

Step-by-step explanation:

y = -2x ______(1)

7x - 8y = -23 ________(2)

Substituting the value of y in eqn.(1) into eqn (2);

7x - 8(-2x) = -23

7x + 16x = -23

23x = -23

x = -1

y = -2(-1) = 2.
