Answer:

n = 5

Step-by-step explanation:

By the property of intersecting chords within a circle.

$18(n + 1) = 9(n + 7) \\ \\ \therefore \: 18n + 18 = 9n + 63 \\ \\ \therefore \: 18n - 9n = 63 - 18 \\ \therefore \: 9n = 45 \\ \therefore \: n = \frac{45}{9} \\ \huge \red{ \boxed{\therefore \: n = 5}}\\$

Answer:

85 parking spaces

Step-by-step explanation:

Given that :

Parking spaces on floors :

Let first floor = x

Second floor = 2x

Third floor = 2x + 3

Total parking spaces = 428

THEREFORE ;

x + 2x + 2x + 3 = 428

5x + 3 = 428

5x = 428 - 3

5x = 425

x = 425 / 5

x = 85

Hence, there are 85 parking spaces on the first floor

Help on these 2 please!!

Hope this helps
$7 \frac{1}{5} - 2 \frac{3}{5} = \frac{36}{5} - \frac{13}{5} = \frac{23}{5} = 4 \frac{3}{5}$

$8 \frac{2}{5} - 4 \frac{3}{5} = \frac{42}{5} - \frac{23}{5} = \frac{19}{5} = 3 \frac{4}{5}$
good luck

Juan ordered 20 pizzas for a party. 45% of the pizzas have 8 slices each. The remaining 55% of the pizzas have 12 slices each. C

Mama L [17]

Total number of pizzas Juan ordered $20$

Since, $45\%$ of pizzas have $8$ slices.

Therefore, number of pizzas with $8$ slices are: $45\%\times(20)$

$=\frac{45}{100} \times(20)$

$=\frac{45}{10} \times(2)$

$=\frac{90}{10}$

$=9$ pizzas

Also, since, $55\%$ of pizzas have $12$ slices.

Therefore, number of pizzas with $12$ slices are: $55\%\times(20)$

$=\frac{55}{100} \times(20)$

$=\frac{55}{10} \times(2)$

$=\frac{110}{10}$

$=11$ pizzas

Now, there are $9$ pizzas with $8$ slices and $11$ pizzas with $12$ slices.

Therefore, total number of slices of pizza are: $=(9)(8)+(11)(12)$

$=72+132$

$=204$ slices
