Answer:

C. x = 72 degrees.

Step-by-step explanation:

The 2 marked angles are alternate angles between 2 parallel lines so they are congruent. Thus:

x - 20 = 52

x = 52 + 20

x = 72 degrees.

➷ 2) The integral of a constant follows this rule:

adx = ax

In this case, it is 1dx = 1x

This can be simplified to just x

Add a constant to this, to get the final answer of:

x + C

3) The integrals power rule is:

$x^adx = \frac{x^a^+^1}{a +1}$

Substitute the values in:

$\frac{x^5^+^1}{5 +1}$

This can be simplified to:

$\frac{x^{6} }{6}$

Add a constant to this to get the final answer of:

$\frac{x^{6} }{6} +C$

a plane flying with the wind travels 630 mi in 1.5hrs. Flying against the wind , the plane travels 1120 mi in 4hrs. Find the rat

Flauer [41]

$\bf \begin{cases}
r=\textit{rate of the plane}\\
w=\textit{rate of the wind}\\
\end{cases}
\\\\

\begin{array}{ccccllll}
&distance&rate&time(hrs)\\
&\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\
\textit{with wind}&630&r+w&1\frac{1}{2}\\
\textit{against wind}&1120&r-w&4
\end{array}
$

$\bf thus \begin{cases}
630=(r+w)1\frac{1}{2}\to 630=(r+w)\frac{3}{2}
\\\\
1120=(r-w)4\\
--------------\\
630=(r+w)\frac{3}{2}\implies 630\cdot \frac{2}{3}=r+w\\
420=r+w\implies \boxed{420-w}=r\\
--------------\\
thus\\
--------------\\
1120=(r-w)4\implies 1120=4r-4w
\\\\
1120=4(\boxed{420-w})-4w
\end{cases}
$

solve for "w", to find the wind's speed rate,

so hmmm what's the plane's rate? well 420 - w = r :)

10(7k+9p+3) I don’t understand

Llana [10]

Answer:

4=0

Step-by-step explanation:

Simplifying

(-9p + 7) + -1(-9p + 3) = 0

Reorder the terms:

(7 + -9p) + -1(-9p + 3) = 0

Remove parenthesis around (7 + -9p)

7 + -9p + -1(-9p + 3) = 0

Reorder the terms:

7 + -9p + -1(3 + -9p) = 0

7 + -9p + (3 * -1 + -9p * -1) = 0

7 + -9p + (-3 + 9p) = 0

Reorder the terms:

7 + -3 + -9p + 9p = 0

Combine like terms: 7 + -3 = 4

4 + -9p + 9p = 0

Combine like terms: -9p + 9p = 0

4 + 0 = 0

4 = 0

Solving

4 = 0

2.5(6v-4)=10+4(1.5+0.5)

asambeis [7]

$2.5(6v-4)=10+4(1.5+0.5)\\\\(2.5)(6v) - 2.5(4)=10 + 4(1.5) + 4(0.5)\\\\15v - 10 = 10 + 6+2 \\\\15v - 10 = 18\\\\15v - 10 + 10 = 18 + 10\\\\15v = 18\\\\\frac{15v}{15} =\frac{18}{15} \\\\v = \frac{18}{15}\\\\v = \frac{6\times 3}{5\times 3}\\\\v=\frac{6}{5}\\\\\boxed{\bf{ v = \frac{6}{5} = 1\frac{1}{5}}}$

A total of 231 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student t

Bumek [7]

Well if there are 231 tickets, then divide 231 by three, that will equal 77, so if you see what i am doing,i am diving all tickets by 3 so that the students get 2/3 and the adults get the pther 1/3. so the answer is 77.
