Opposite interior angles are equal, so

4x - 10 = 2x + 20

2x - 10 = 20

2x = 30

x = 15

Answer:

4x-10=2x+20(being alternate angle)

or,4x-2x=20+10

or,2x=30

or,x=30/2

or,x=15

again,

4x-10 (putting the value of x)

=4×15-10

=60+10

=70

2x+20 (putting the value of x)

=2×15+20

=30+20

=50

solved !!!

What fraction of the students in the class named baseball their favorite sport
mojhsa [17]

now, let's take a peek at the denominators, we have 3 and 8 and 12, we can get an LCD of 24 from that.

Let's multiply both sides by the LCD of 24, to do away with the denominators.

so, let's recall that a whole is "1", namely 500/500 = 1 = whole, or 5/5 = 1 = whole or 24/24 = 1 = whole.  So the whole class will yield a fraction of 1/1 or just 1.

\bf ~\hspace{7em}\stackrel{\textit{basketball}}{\cfrac{1}{3}}+\stackrel{\textit{soccer}}{\cfrac{1}{8}}+\stackrel{\textit{football}}{\cfrac{5}{12}}+\stackrel{\textit{baseball}}{x}~=~\stackrel{\textit{whole}}{1} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{24}}{24\left(\cfrac{1}{3}+\cfrac{1}{8}+\cfrac{5}{12}+x \right)=24(1)}\implies (8)1+(3)1+(2)5+(24)x=24 \\\\\\ 8+3+10+24x=24\implies 21+24x=24\implies 24x=3 \\\\\\ x=\cfrac{3}{24}\implies x=\cfrac{1}{8}

Mr. Winking is purchasing a car and needs to finance $24,000 from the bank with an annual percentage rate (APR)
babymother [125]

Answer:

<em>The monthly payment is $450.71</em>

Step-by-step explanation:

<u>Financial Computing </u>

Given the loan amount A, the loan term t, and the APR (annual percentage rate), the montly payment is computed as

\displaystyle P=\frac{A}{f}

where f is

\displaystyle f=\frac{1-(1+i)^{-n}}{i}

The provided data is

\displaystyle A=24,000

\displaystyle r=4.8\%

\displaystyle t=5\ years

Since the payments will be made monthly, the values of n and i are:

\displaystyle i=\frac{4.8}{100\times12}=0.004

\displaystyle n=5\times12=60\ months

Calculating f:

\displaystyle f=\frac{1-(1+i)^{-n}}{i}

\displaystyle f=\frac{1-(1+0.004)^{-60}}{0.004}

\displaystyle f=53.25

Now for the payments:

\displaystyle P=\frac{24.000}{53.25}=450.71

\boxed{\displaystyle P=\$450.71}
