Answer:

\boxed {\angle PQR = 134\textdegree}

Step-by-step explanation:

Both angles are <u>Supplementary</u> (Two angles that add up to 180°). So, write an expression using the following measurements of both \angle PQR and \angle RQS and 180:

\angle PQR = 3x + 5

\angle RQS = x + 3

3x + 5 + x + 3 = 180

Solve:

3x + 5 + x + 3 = 180

4x + 5 + 3 = 180

4x + 8 = 180

4x + 8 - 8 = 180 - 8

4x = 172

\frac{4x}{4} = \frac{172}{4}

x = 43

-After you have the value of x, use it to the expression of \angle {PQR} to get the actual answer of \angle PQR:

-The value of x:

x = 43

-Solve for the measurement of \angle PQR:

3x + 5

3(43) + 5

129 + 5

134

-The measurement of \angle PQR:

\boxed {\angle PQR = 134\textdegree}

Suppose you want to build a small walkway around your garden so that there is someplace to walk around and work on your vegetabl
wolverine [178]

Answer:

Approximately 3.5 feet - Option B

Step-by-step explanation:

Imagine that you have this walkway around the garden, with dimensions 30 by 20 feet. This walkway has a difference of x feet between it's length, and say the dimension 30 feet. In fact it has a difference of x along both dimensions - on either ends. Therefore, the increases length and width should be 30 + 2x, and 20 + 2x, which is with respect to an increases area of 1,000 square feet.

( 30 + 2x ) * ( 20 + 2x ) = 1000 - Expand "( 30 + 2x ) * ( 20 + 2x )"

600 + 100x + 4x^2 = 1000 - Subtract 1000 on either side, making on side = 0

4x^2 + 100x - 400 = 0 - Take the "quadratic equation formula"  

( Quadratic Equation is as follows ) - x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a},

x=\frac{-100+\sqrt{100^2-4\cdot \:4\left(-400\right)}}{2\cdot \:4}:\quad \frac{5\left(\sqrt{41}-5\right)}{2},

x=\frac{-100-\sqrt{100^2-4\cdot \:4\left(-400\right)}}{2\cdot \:4}:\quad -\frac{5\left(5+\sqrt{41}\right)}{2}

There can't be a negative width of the walkway, hence our solution should be ( in exact terms ) \frac{5\left(\sqrt{41}-5\right)}{2}. The approximated value however is 3.5081...or approximately 3.5 feet.

What is the slope of the line through (1, -1) and (5. – 7)?
Vladimir [108]

Answer:

-3/2

Step-by-step explanation:

Given two points, we can find the slope by

m = (y2-y1)/(x2-x1)

    = (-7 - -1)/ (5-1)

    = (-7+1)/(5-1)

    = -6/4

    = -3/2
