At the beginning of summer, Mark has $200 in savings and Ryan has $350. The brothers have mowing jobs set up for the summer. Bec

zepelin [54]

Answer:

$m = 200 + 20j$

$r = 350 + 15j$

Number of jobs is 30

<em></em>

Step-by-step explanation:

<u>Variable representation</u>

Let Mark's total earnings for moving be m

Let Ryan's total earnings for moving be r

Represent the number of jobs with j

<u>Setup equation</u>

Mark:

$Initial\ Savings = 200$

$Rate = 20$

So, the total savings is:

$m = 200 + 20j$

Ryan

$Initial\ Savings = 350$

$Rate = 15$

So, the total savings is:

$r = 350 + 15j$

<u>To get the number of jobs they save the same amount.</u>

We have:

$m = r$

Substitute values for m and r

$200+20j = 350+15j$

Collect Like Terms

$20j - 15j = 350 - 200$

$5j = 150$

Divide both sides by 5

$j = \frac{150}{5}$

$j = 30$

<em>Hence, the number of jobs is 30</em>

The simplified ratio of 32 ft over 12ft is

denis23 [38]

Start by the basic ratio:
32/12
Divide each side by four, as they both have a factor of 4
32/4=8
12/4=3
New ratio=8/3
The simplified ratio of 32 ft over 12 ft is 8/3

Since it's a regular pentagon, all it's sides are equal so let's solve for x

$\hookrightarrow \: 3(x - 1) = 5x - 6$

$\hookrightarrow \: 3x - 3 = 5x - 6$

$\hookrightarrow \: 3x - 5x = - 6 + 3$

$\hookrightarrow \: - 2x = - 3$

$\hookrightarrow \: x = \dfrac{ - 3}{ - 2}$

$\boxed{\boxed{x = \dfrac{3}{2} }}$

now let's find the measure of each side, i.e

$\hookrightarrow \: 5x - 6$

$\hookrightarrow \: (5 \times \dfrac{3}{2}) - 6$

$\hookrightarrow \: \dfrac{15}{2} - 6$

$\hookrightarrow \: 7.5 - 6$

$\mathrm{\hookrightarrow \: 1.5 \: units}$

perimeter = 5 × side length ( for a regular pentagon )

$\hookrightarrow \: 1.5 \times 5$

$\boxed{ \boxed{ \: \: \: \: \: \: \: \: 7.5 \: \: units \: \: \: \: \: \: \: }}$
